This article is in continuation with our previous article Stirling Engine Project Idea. In this article we will discuss various types of Stirling engines and their working in detail. Sterling engines work on simple principle of  temperature difference where compression and expansion of gases produces useful work. Even after the advancement of Internal Combustion engines, Stirling engines are still used in different industrial applications for they are more efficient. Working model of Stirling engines can easily be made hence it can be very good Mechanical Engineering Project Idea for you.

Types Of Stirling Engine:

Alfa type Stirling engine:-

Alfa stirling engine consists of two cylinders .

One cylinder (expansion cylinder) is kept at high temperature while another (compression cylinder) at low and the passage between the two cylinder contains the regenerative fluid (gas) working of the Alfa type Stirling engine as discussed above that it contains two cylinders one is hot and other cold.

The hot cylinder is fitted inside the high temperature heat exchanger and colder one inside the low temperature heat exchanger. This type of heat engines has a high power to volume ratio though has technical problems because of high temperature of hot piston and durability of its seals. Though there is some additional dead space inside the cylinder to reduce this problem.

  1. Shown in the diagram, nearly all the working gas is in contact with the hot cylinder walls. The gas has been heated and therefore expansion takes place which has pushed the hot piston to the bottom. The expansion continues in the other cylinder (cold cylinder), which is 90 degree behind the hot piston in its cycle thus extracting more work from the hot gas.
  2. Now in the second diagram, the gas is now at its maximum volume. The hot cylinder begins to push most of the gas into the cold cylinder, where it cools and the pressure drops considerably.
  3. As you can see in the third diagram, almost all the gas is in the cold cylinder and cooling continues. The cold piston which is powered by the flywheel momentum compresses the remaining part of the gas.
  4. Here in the fourth diagram, you can see the gas reaches its minimum volume and now it will expand in the hot cylinder where it is heated once more thus driving the hot piston in its power stroke.

This completes the whole working of the Alfa type Stirling engine. Now we come to beta type stirling engines.


Beta type stirling engine:

Beta type stirling engine consists of only one cylinder with hot and cold ends, a loosely fitted displacer which shunts the air (working gas) between hot and cold end and a power piston at the end of the cylinder which drives the flywheel. The flywheel is connected to the piston with help of connecting links.

A cross section of a beta stirling engine design is shown in the diagram. Different parts includes-

  1. hot cylinder wall
  2. Cold cylinder wall
  3. Coolant inlet and outlet pipe
  4. Thermal insulation which separates the two cylinder ends
  5. Displacer piston
  6. A power piston
  7. Flywheel
  8. Linkages it removes the technical problems of hot moving seals unlike the Alfa type. Displacer and the power piston arranged in the same shaft. The displacer in this case does not extract power from the expanding gas but serves to shuttle the working gas between hot and cold ends.
  1. The power piston has compressed the working fluid, the displacer piston has moved so that most of the gas gets closer to the hot heat exchanger.
  2. The heated gas increases the pressure inside the cylinder and pushes the power piston to the farthest limit of the power stroke.
  3. The displacer now moves and pushes the gas to the cold end of the cylinder.
  4. Finally the cooled gas is compressed by the flywheel momentum and it takes less energy as its pressure drops when it is cooled.

As we have discussed earlier that it is a closed cycle process which means the heat driving it must be transmitted from a heat source to the working fluid and eventually to the sink. The heat source for it can come from burning of fuel, waste combustible products, landfill gases etc as it does not comes in contact with internal parts. Other sources can include concentrated solar energy, geothermal energy nuclear energy, waste heat and bio-energy which are in abundance in nature.

Gamma Stirling Engines:

Gamma Stirling engines are similar to beta engines i.e these are also displacement type but in this, the power piston is mounted in separate cylinder along side displacer piston cylinder but still connected to same flywheel.

This ends our discussion on sterling engines. Check out various Mechanical engineering projects ideas based on Stirling engines. If you want further information on any project, let us know.

In this article we will provide you a thesis report on Whittmore-Petrenko Proving ring or simply proving ring. In this project on proving ring we will provide you background history on proving ring, types of rings, materials required, design, construction and working of  Proving ring. The project covers Strength of materi

als among various other subjects of mechanical engineering.


Proving ring is a force transducer concept designed, analyzed and developed to be used in laboratory experiments to measure forces. The elastic behavior of the proving ring was analyzed using Castigliano’s second theorem and the results were found to be about 1% accurate.

The proving ring is a metal ring equipped with means of measuring deflection when under load. The concept of proving ring was created originally by Whittmore and Petrenko at the US National Bureau of standards.


Force transducers are commonly used in engineering applications like weighing scales, verification of material testing machine, thrust measurement etc. Ring shaped transducers provide an ease in manufacturing and are widely used for the measurement of force.

The proving ring is a elastic metal ring with a means of measuring deflection when it is under load. It is used to measure force. The ring is currently used in laboratory exercises and in research projects in fluid mechanics.

Dolphin Like Sea Glider

We all have been heard many times in debates and discussions that global warming is responsible for the melting of polar ice. However this is not the only reason for the melting, the swirly eddy currents add to that. The findings are based on the information gathered by the Robotic ocean gliders.

The Findings

Ice sheets of west Antarctica are melting at a faster rate and it is predicted that if it continues with the present rate might raise the sea level by 3 meters. Scientists have been a close eye for many years on the warm water near the coast of west Antarctica and got into conclusion as one of the main reason for the melting of the ice. It remained a mystery for some time on how it is happening. Finally scientists have gathered some crucial information regarding ice melt.

How they got the information?under water dolphin glider

The obvious question that comes to mind is how the hell all the times scientists find the reasons and solids information for the concerned problems? Well, they do research simple.  This time they took help of three robotic gliders which look like the dolphins under the sea.

The gliders are 2 meters in length –around the size of a bottle –nosed dolphin. They were deployed deep down the ocean near Antarctica to measure the salinity and temperature. After two months of research they found that eddy currents, swirls of warm water are the reason, reaching the surface. This leads to the melting of the coastal ice.

Eddies current are actually the instabilities in a medium caused by certain factors. You can imagine eddies as circular motion of the liquid medium forming the whirlpool, a perfect example would swirl formed while mixing the sugar in a cup of tea by the use of spoon, Eddies facilitates mixing. Hence when we talk here about eddies current in ocean that means mixing of heat into ocean water efficiently.

Researchers used ships to gather ocean data in the past, the method being expensive having lots of constraints. However the gliders like this enhances the capabilities of taking ocean samples for much longer time. These battery powered bots are extremely energy efficient.

How Dolphin Gliders do it?

These gliders dive into the ocean like a dolphin. The batteries power a pump that pushes water into a specially designed compartment within the glider. It makes it heavier than the sea saline water making it to sink. When they it needs to come upon the surface, water is pumped into a bladder which is incorporated into the dolphin surface, making it more buoyant and causing to rise.

Each time when glider comes to the surface, it calls the researchers via mobile phone inbuilt device. This allows the researcher to find the dolphin and collect the information it has gathered from deep down the sea.

Further the team wants to adopt a more advanced sophisticated glider to study the Drake Passage. This is a patch of ocean between the southern tip of South America and Antarctica. This narrow stretch of ocean is known for its deep waters coming at the surface. And making it ideal to study the CO2 exchange between the ocean and the atmosphere.

The Project Idea which you can take out of it:-

Well there are lots of researches has to be done inside the ocean and day after day new things come up. You being the engineers can help these researchers by making some new kind of Drones with new sensors. You can make bots that can directly transmit the information in the real time even if the glider fails. As far as college Engineering project is considered, you can make a prototype of it by incorporating batteries and propeller into it.

In case you have money constraints, you can make static model showing areas in it for more advancements. We never know when we become a crucial inventor.

Finally it’s always important to share information with the mates. I would be pleased if you share it in various networking sites. Do comment if you feels like having a potential project idea and loved it.

bionic bird project for engineers

Bionic Bird Project for Engineering Students

Hello friends, your Engineer buddy, have brought you a new project idea for your engineering projects. Today’s idea is world’s first furtive civilian drone. It’s a bionic bird.

The unique characteristic of this bionic bird is that it flies not with the rotating wings like in helicopter drones but uses its wings like a bird in up and down motion to fly. The most interesting is it can fly in a group of the real bird without even making them realize that it’s unreal. This bionic bird like drone is shown attracting other bird and predators.

Following is the demonstration:-

 Construction and working

The bird’s body is constructed with high quality wear resistance foam. The wings are made of the carbon fibres for weight reduction and increased durability. It is incorporated with a Bluetooth 4.0 for communication via smartphone. Soon it would be controlled with an android application too.

There is an on board battery which allows it fly for around 8 to 10 minutes and took 12 min to charge with the egg shaped charger. Presently it does not have too much practical applications but later version would have improvements such as inbuilt HD camera with live streaming, control with a wrist band, and hovering ability like a humming bird. This drone can be operated within a range of 100 meters.

Following is the video showing its internal gear system. The video represented  rotatory motion conversion to reciprocatory motion in  bionic bird.

It is sort of a good toy to play around for some time.

Hope you liked this article and you really loved the concept than don’t forget to share with your friends and amaze them with the bot.


drone ambulance project

Hello folks, today I have brought a new application of flying copter over the conventional ways. When an ‘Engineering Student’ does something innovative in his/her field that fascinates me and motivates too to inspire others in doing so. The latest innovation is a ‘drone ambulance’ created by Alec Momont, an engineering student from Delft University of Technology in the Netherlands.

The time taken to receive a person with severe cardiac arrest is often a deciding factor between the life and death. If the person is untrained then it became tricky to operate public defibrillators. He decipher the situation and came out with an idea of removing this difficulty by constructing a drone specifically for the scenario.

He proposed the solution by making an ambulance drone, carrying a defibrillator to the patient deployed within fraction of time before the emergency services to arrive.

How does it work?

In case, a patient has a cardiac arrest and makes an emergency call, the ambulance drone tracks the call location using an inbuilt GPS for navigation and fly with a speed of 100km per hour. An operator operates it and helps like a paramedic, gives instruction to someone nearby on how to use the defibrillator to treat the patient. An inbuilt camera is incorporated that allows the operator ensuring the defibrillator is being used correctly.

The ambulance drone is six winged copter that can travel to a location within 12 square km in a minute. According to the maker, it increases patient’s probability of survival ten times when met with cardiac arrest.

The design prototype is developed with the frame made of carbon composites. The structure is light weight capable of carrying itself with the requiring tools. It would replace the conventional medical toolbox that weights around 3 to 5 kg. Also the inbuilt loudspeaker helps reducing the caused due to the situation while helping the person in need.

In a press release, currently 20 percent untrained people are able to successfully apply the defibrillator. This rate though can be increased upto 90 percent if people are provided with the instructions at the incidence.

The ambulance drone is in progress for increasing efficient and ability to avoid obstacles mid-flight. We all hope that it would take the sky and save many lives in future.

­­ Ambulance Drone over car ambulance is better because

  • An average ambulance takes around 30 min to reach the patient
  • There are possibilities of trapping into traffic situations too.
  • Sometimes to navigate person is not an easy task.
  • The key to win the death and life combat is to be quick; ambulance drone increases the winning possibilities for that.
  • Effectiveness diminishes by 10 percent for every minute that passes by before the implication of the defibrillation.

I hope that this article would be helpful you in engineering project ideas. We are the engineers and that’s the prestige. We help people in innovating what they need, making their life easier. I insist you to invent something like this.

In case you have any query or technical help related to the article, do ask. I would be grateful hearing from you. If you like the article do comment, share via Facebook, Twitter, Google +, etc.

Happy Mothers Day Poems 2015

 We are always fascinated with the objects that fly in sky. We have the intrinsic desire to fly like a bird, hovhendo hoveboard, magnetic levitationer like a bug and love adventure related to sky. The researchers have created a hover board which is a combination of a skate board and hover craft. It levitates above ground. A Japanese technology team also demonstrated ultrasonic levitation working in three dimensions.

This is the technology which you normally would see in the science-fiction movies. With this technology, hovering car and trains could revolutionize the world and add a new way to transportation. They called the hoverboard a hendo, a special skateboard. The nonferrous material let Hendo to hover and is conductive in nature. We all know magnetism from childhood that like poles attracts and unlike repels. It is the old known concept behind the technology.

The board has disc shaped motors acting as four engines that create a magnetic field which react with the non-ferrous conductive material producing the secondary magnetic fields. Each field repels the other, allowing the board to hover above the ground. The hovercraft uses magnetic field architecture and only reacts to certain materials such as copper and aluminum. The blue light adds to the aesthetics. The working of the Hendo is quieter. Tough part while making the project was with the balancing, described by Earns haw’s theorem. The theorem state: that it’s utterly tough to balance magnets when they are repelling.

The magnetic hovercraft was restricted in a track for equilibrium. The device is capable of weighing upto 136 kg hovering few cm. above the ground. The Hendo only float above the ground or park made for hovercraft. It cannot float above the water. They are working to get some more advancement with the major goal to levitate the house. Presently 50,000 kilogram train is already running on track like the hover train, Levi train. The cost of such board is $10,000.

In the pioneer’s festival in Vienna, the most advanced flying car was unveiled by the Slovakia based company, aeromobil. The aeromobil 3.0 is the name of their prototype. It has accommodations for two passenger and has length of the limousine. The car make you feel like the luxury sedan. The amazing feature of the car, which makes it advanced, is that it can transform from car to airplane within few minutes and reminds us like a transformer from the film- Transformers. The speed of the vehicle in car form is upto 160km per hour and 200km per hour as a flying aircraft.

Front view makes it look like a car whereas back view makes feel like a private jet.  The aeromobil 3.0 requires 250metres of open field, pavement or grassland to take off and 50metre space to land. When one feel it to fly, just a touch of a button ,it opens its wings like from the side automatically an a large  becomes a small flying plane. It can be kept at home garage just like a car when we are done with the flying.

The company says if one need to buy the car, they must possess the pilot’s license, which is fair enough. We certainly don’t want someone to crash it onto or roofs. Presently only trained pilots are permitted to test the aeromobil 3.0.

volocopter engineer project

Introducing -Volocopter:  final year Major project

Greetings to all the engineering aspirants. One of the strong instinct of human being was always was to fly like a bird in the sky. In early time it was considered impossible but with the evolution of human being and advancement in the technology, we ‘humans’ made that possible and opened the doors of our mind. With that, we believed in us and can achieve whatever we think of. Many of the Engineering students still intrigued with the flying objects and aspire to make them by their own. For them, we have brought one of the idea which you can take and go and for it.The researchers and makers named 18 rotor helicopters as volocopter.

Volocopter Simulation

The experiment of flying the real volocopter is done by the simulation process.  In the simulation, 5 minutes of flight instruction is given to the person, which includes steps for taking off, moving it to front, left, right, etc. The simulation is of the UK city of Liverpool. It mimics perfectly the real world.  The person is allowed to fly it even if he has no flying experience. Developers said that it uses an early version of the easy to use control panel and would form a basis of a much malign concept i.e. the flying car.

Cars that transformed into a flying helicopter are usual approaches and such kind of prototype is already launched by AeroMobil of Bratislava, Slovakia in a technical conference. The major drawback of ‘road able car’ is that it still need an airport for the takeoff and has failed since 1950s. Those are user friendly and still require technical abilities to fly one. Not to forget this point that it would not replace the cars from the roads and help ease road congestion.  What is required a system, which can take a vertical takeoff and system that can fly one point to another strictly.


final engineering project idea

However by the end of the year that would be possible with the volocopter. Other researches are in progress like the ‘My copter’ by European developers with the simple yet efficient flight control interface. One is of which is based on a car steering wheel plus the camera with added sensors. That will let the flying cars automatically avoid each other hitting, without the involvement of the user. Apart from this, they are working on flocking software that automatically plots GPs routes and paths to locate a landing spot in bad weather conditions. This project is seen as the key part of a low – congestion transport system in future. Unlike helicopter pilots who take hundreds of hours to master, users will get trained for such fly copters in 5 hours who never have an experience before, developers claimed.

Volocopter Project Specifications

Sources say, within two years, an 18-rotor powered by battery helicopter would be on sale to rich commuters who have dreamed of open skies instead of gridlocked highways.

The Volocopter is incorporated with 18 rotors, each of which is 1.8 meters long, working in counter-rotating pairs around a circular made frame. Though it looks odd, this arrangement means the torque effects of each pair cancel outs and the vehicle just goes up and down, or side to side, by changing the speed of different rotor pairs. The prototype has nine lithium-ion battery packs, each driving two motors that currently allow it to fly for 20 minutes duration. The joystick works in the same manner as a quad-copter remote control panel. If you let go of the joystick, the Volocopter keeps hovering where you left it, developers says.

We hope this article would be helpful to you. In case you have any query regarding the article or want to know some technicalities, please don’t hesitate to ask. We would love to reply you to the most possible way we can. Stay tuned with us for other Project Ideas and Engineering Projects.

Termite-Inspired Robots Can Build Unsupervised

Greetings to all the science buddies. We are always fascinated by the robots and the science behind robotics. Our Hollywood films are too intrigued by the robotic engineering and that is one of the reason they incorporated all they incorporates sci-fi robots and their amazing abilities. The films we can see most of the robots or arterial intelligence are- iRobot, Terminator series, Transformer series, Wall-E etc. and the list goes on. One of the latest works on artificial intelligence and robotics is today’s project. You can take lots of ideal or references to make similar stuffing and become part of the noble cause.

A team of engineers and computer scientists at ‘School of Engineering and Applied Sciences (SEAS)’ and the Wyss Institute for Biologically Inspired Engineering at Harvard University have produced an autonomous robotic construction crew. The most appealing character of the crew is that it requires no supervision. It does not require an eye in the sky, no communication to guide, just simple robots. They cooperated to each other and act intelligently themselves modifying the environment. The team got its inspiration from Termites so they call it the Termite Crew. The Harvard Termite System corroborates that collective system of their robots can build complex, 3-D structures without the want of any central command or prescribed roles. The result their four year hard work was presented at AAAS 2014 Annual Meeting.

Now one obvious query you all must have what can they build so they can make towers, castles, pyramids out of foam bricks and autonomously builds the staircase to reach the higher levels for adding bricks and materials for construction when they need. In the near future such robots could lay sandbags in advance of the flood, etc. and perform construction tasks on Mars and moon etc.

On an Interview with the core faculty member  while discussing the amazing  robotic crew She says “The key inspiration we took from termites is the idea that you can do something really complicated as a group, without a supervisor, and secondly that you can do it without everybody discussing explicitly what’s going on, but just by modifying the environment”  The lead author also  said that most human construction projects today are performed by the trained workers  in hierarchical organization . We all are pretty much aware that when a construction project is started we do have a blue print and plan. the foreman then directs his crew members and supervise them .while in the termites world the queen does not instruct  each individual  member but everyone is aware of  what other the termite is doing and the current overall state of the job they are accomplishing.

termites botes

The curious geeks want to know by now, what is that concept on which this system depends? The answer is ‘Stigmergy’ which is a kind of implicit communication. The bots observe each other’s changes to the environment and acts accordingly. Each individual robot executes its building process in parallel with the others without being aware who else is working in the same real time. This means that the same set of instruction can be executed by ten robots or ten thousand. This system is a perfect epitome of concept for scalable, distributed artificial intelligence. The bots are employed with simple sensors and three actuators.

This system is a plus in contrast to the previous concept where a central controller is needed or an eye in the sky. It guides the whole crew and keeps an eye on them all the time. The system works efficiently if the crew of the robots is small but with the increase in no say- 500, becomes complex and difficult to manage. On the other hand if there occur some problem with the central control, leads to failure of the whole crew system.

Following are some points to decipher about the termite Crew:-

What can a TERMITES robot do?

  • Move forward, backward, and turn in its own place.
  • Climb up or down a step the height of one brick.
  • Pick up a brick, carry it, and deposit it directly in front of itself.
  •  Detect other bricks and robots in immediate vicinity.
  •  Keep track of its own location with respect to a “seed” or brick.

What instructions do the TERMITES robots follow?

  • Obey predetermined traffic protocols.
  •  Circle the growing structure to find the first, “seed” brick (for the orientation).
  •  Climb onto the structure.
  • Obtain a brick.
  •  Attach the brick at any vacant point that satisfies local geometric requirements.
  • Climb off the structure.
  • Repeat.

We, Mech- Ant – Group is also inspired by the working of ants all together to accomplish the task too. We hope this article would be helpful to you. In case you have any query regarding the article or want to know some technicalities, please don’t hesitate to ask. We would love to reply you to the most possible way we can. Stay tuned with us for other Project Ideas and Engineering Projects.

Below is an official video showing the construction by these Termites Robots:-

Stirling engines have been in use since 18th century, way before internal combustion engines were introduced. These engines are simple to make with materials easily available in our homes and hence you can always find mechanical engineers looking to work on a project idea based on Stirling engine. Keeping that in mind we are going to provide all detail about working principal of Stirling engines.

What is Stirling Engine?

Stirling engine is a heat engine which operates on cyclic compression and expansion of working fluid (air or any other gas like hydrogen etc) kept at different temperature levels. There is direct conversion of heat energy into mechanical work. The engine contains a permanent gaseous working fluid inside and hence is an example of closed system (only heat transfers through the boundary of the cylinder). The cylinder also acts as heat exchanger.

Now let’s discuss the brief history of this amazing engine.

A Scottish inventor MR. Robert Stirling  in 1816 invented the first practical closed cycle air engine The then inventors were motivated with this engine to create safer and efficient steam engines of the time because of the following reasons—

-The explosion in the boilers was frequent thus causing injuries and deaths of the workers

– Its working was quiet unlike steam engine.

– Its efficiency was high and could have operated by any source of heat thereby saving fuel.

However later it was not able to compete with steam engines as they become safer and efficient. It was limited to domestic motor and in the early of 20TH   century Stirling engine was then replaced by electric motors and internal combustion engines. Stirling engines then was completely forgotten and merely used for the ventilating fans and toys etc. later in 1950 Philips was expanding its sale of radios but electricity and batteries were not available everywhere hence they came up with the idea to a portable electric generator which can be used easily hence Stirling engine solved this problem which had the ability to run on a variety of heat sources.­­­­­

Working of Stirling engines

The design of the engine is such that the working fluid is compressed in the colder portion of the engine and expanded in the hotter portion which results in the net conversion of heat into external mechanical work. The efficiency of the Stirling heat engine is increased by an internal heat exchanger.

Watch this amazing animation to get the basic idea of its working.


The Stirling engine is classified as external combustion heat engine as all the heat transfers to and from the working fluid (air) takes place through the boundary of the cylinder hence isolating the combustion process and any contaminants it may produce from the working part of the engine. Unlike the internal combustion engine where burning of the fuel takes place inside the engine. It may also fall into the category of reciprocating piston engine.

Types of Sterling Engines:

Now lets take a look at different types of Stirling Engines. For more details on working of  various types of Stirling engines click on respective links.

There are two types of Stirling engines:

  1. Alfa Type Stirling Engine:

    These engines have two pistons in independent cylinders as shown in figure.
    One cylinder (expansion cylinder) is kept at high temperature while another (compression cylinder) at low and the passage between the two cylinder contains the regenerative fluid (gas).

  2. Beta Type Stirling Engine:

    These are displacement type Stirling engines and are further divided into beta and gamma type.
    Beta type sterling engine consists of only one cylinder with hot and cold ends, a loosely fitted displacer which shunts the air (working gas) between hot and cold end and a power piston at the end of the cylinder which drives the flywheel. The flywheel is connected to the piston with help of connecting link.
    A gamma Stirling is similar to beta Stirling having the power piston mounted in separate cylinder alongside the displacer piston cylinder. It is still connected to the same flywheel.


With this we come to end of this article. To know more about different types of Stirling engines, click on respective links provided.  Check out various project ideas based on Stirling engine which you can build at home as minor project or major project.
