Pistonless pump that makes them different from that of turbopump ,is the absence of piston.
This is a unique technique. In this ,no. of rotating parts is very less as compared to that of turbo pump.
As the world is hard pressed with the energy and fuel crises, compounded by pollution of all kinds, any technologies that bring out the solutions to this problem is considered as a bounty. In one of such new technologies, is the development of a new car called as compressed air car which does not require any of the known fuels like diesel, petrol, CNG, LPG, hydrogen etc. this works using only compressed air. This replaces all types of to-date known fuels and also permanently solves the problems of pollution as its exhaust is clean and cool measured practically as low as 5ºC. A proto type, a horizontal, single cylinder low speed engine was modified to run on compressed air. Since this engine runs only on high pressure compressed air, the exhaust of which is undoubtedly only air, making it a zero pollution engine. No heat is generated because there is no combustion of fuel, hence this car needs no cooling system and it result in reduced cost, weight, volume and vibration. Early cost analysis shows that it's very cost effective and the operational cost is ten times less than that of petrol or diesel. Experimental analysis were carried out on this modified car to find out its performance characteristics like brake power, mechanical efficiency, overall efficiency, air to Air ratio, volumetric efficiency, cost analysis etc. Though the efficiencies were low as the frictional forces were high for the proto designed engine, however the concept can be applied on a professionally designed engine to improve the car performance.
This engine is constructed in such a way that it can produce higher efficiency by emitting zero emission of harmful gases,because of complete burning of fuel.It is light,small and of low cost.It is benificial for the environment.It can solve the problems of over consumption of fuel.It creates a revolution in the field of engine mechanism.It has two strokes more than the four stroke engine.In future it may be used in every technical field due to higher output and low pollution factor.
The wheel is probably the most important mechanical invention of all time. The wheel has been continuously driving our civilisation like a catalyst in a chemical reaction. Nearly every machine built since the beginning of the Industrial Revolution involves a single basic principle embodied in one of the mankind’s truly significant inventions.
Tyre is a hoop that covers a wheel, around the wheel rim to protect it and enabling better vehicle performance by providing a flexible cushion that absorbs shock while keeping the wheel in close contact with the ground.
Creating a new non-pneumatic design for tyres has more positive implications than one might think. For one thing, there are huge safety benefits. Having an airless tyre means there is no possibility of a blowout, which, in turn, means the number of highway accidents will but cut significantly. Even for situations such as Humvees in the military, utilising non-pneumatic tyres has a great positive impact on safety. Tyres are the weak point in military vehicles and are often targeted with explosives. If these vehicles used airless tyres, this would no longer be a concern.
There is also an environmental benefit to using this type of tyre. Since they never go flat and can be retreaded, airless tyres will not have to be thrown away and replaced nearly as often as pneumatic tyres. This will cut down landfill mass significantly.
Because of the benefits, I believe that it is extremely important that research and production of airless tyres are continued and increased. This type of innovation works well in conjunction with several engineering codes of ethics, and thus should be embraced by engineers everywhere. Cars are things that people use every day, so any improvements over existing designs would affect the lives of the majority of people. Learning about such a topic, therefore, I believe holds extreme value- especially for us freshmen engineering students. In doing research for these kinds of topics that hold significant meaning, we can see that what we will do can make a difference.

Design and Optimization of Valveless Pulsejet EngineIJERA Editor
Simple design and efficiency make pulsejet engines attractive for aeronautical short-term operation applications.
An active control system extends the operating range and reduces the fuel consumption considerably so that this
old technology might gain a new interest. During the operations of these pulsejet engines the surfaces of engine
will get more heated. In order to cool the engine surface and to get more thrust we have attached an additional
component called secondary inlet in that valve less pulsejet engine. The pulsejet is the only jet engine combustor
that shows a net pressure gain between the intake and the exhaust. The pulsejet is the only jet engine combustor
that shows a net pressure gain between the intake and the exhaust. We choose the LOCKWOOD’s design of
pulsejet engine. By using the CFD analysis we have analysed the modified design of valveless pulsejet engine.
This project provides an overview of this unique process and the results of these design modifications are
reported.

2. INTRODUCTION
• Pump is a device which converts mechanical energy into hydraulic
energy.
• Principle: A partial vacuum created when internal parts of pump
receives mechanical energy .
• Oil is forced into pump due to atmospheric pressure on oil and
suction created by pumping element.
• Oil is squeezed b/w pump elements which increases pressure of fluid
and then is forced out of pump and the cycle continues.

3. Cont..
• A Piston less pump is a type of pump designed to move fluids without
any moving parts other than three chamber valves.
• This pump provides increased design flexibility & increase
damage and fault tolerance.
• Absence of piston leads to less friction losses& hence improves
efficiency of engine considerably.
8/24/2016 Piston less Pump 3
4. WHY PISTONLESS PUMP?????
• Turbo pumps have a reputation
for being extremely hard to
design to get optimum
performance
• Low efficiency – ONLY 55%
• Weight of pump is high hence
Undesirable to use.
TYPICAL TURBO PUMP SETUP8/24/2016 Piston less Pump 4
5. NECESSITY
• The turbo pumps used in rocket are very heavy, containing many rotating
parts by which there are more frictional losses which more consumption of
fuel there by decreasing the efficiency of the engine .
• since the rocket has to remain stable in the space, is difficult and require
complex methods for it. If this pump gets any fault then its reappearance
requires long time. So, there must be such a device which overcomes all the
drawbacks of the turbo pump.
• The Piston less pump is the solution for the problems faced by using turbo
pumps.

7. DUAL PISTONLESS PUMP
NASA has designed, built and tested
a simple, light weight pump (dual
piston less pump) for use in liquid
propelled rocket where a reliable
pump with minimal moving parts is
needed.
This pump has the potential to
reduce the cost and increase the
reliability of rocket fuel pumps by a
factor of 20 to 100.

8. WORKING MODEL OF
ROCKET FUEL PUMP
• The pump shown is equipped with
electronic level sensors and air
cylinder actuated ball valves. The
pump works as predicted and it will
be easy to reconfigure it to pump LOX
and jet fuel.
• This type of pump will make rocket
propulsion systems much more
reliable and less expensive than that
of the turbo jet pump.

9. WORKING OF PISTONLESS
PUMP (Rocket engine)
It consists of main tank and Two pumping
chambers . The pump starts with both
chambers filled.
Each one being alternately refilled and
pressurized .
One chamber is pressurized, and fluid is
delivered to the rocket engine from that
chamber(Step 1).
8/24/2016 Piston less Pump 9
10. Once the level gets low in one
chamber, the other chamber is
pressurized;
8/24/2016 Piston less Pump 10
11. Flow is thereby established from
both sides during a short
period until full flow is
established from the other
chamber. Then the nearly
empty chamber is vented and
refilled.
8/24/2016 Piston less Pump 11
12. Finally the cycle
repeats. This results in
steady flow and
pressure. The pump is
powered by
pressurized gas which
acts directly on the
fluid

15. APPLICATIONS
• DEEP SPACE PROPULSION - NASA has a need for high Power
propulsion to land and spacecraft on the moons of Jupiter and
beyond. This pump would allow these missions to go forward due to
lower weight of the fuel tanks.
• X PRIZE VEHICLE FUEL PUMP APPLICATION- For X-prize competitors, a
the fuel pump will reduce the cost.
8/24/2016 Piston less Pump 15
16. ADVANTAGES
• All the hardware in the pump consists of pressure vessel so the weight is
low.
• The pump can be scaled up or down with similar performance and
minimal redesign issues.
• Low risk development; pump technology has been demonstrated and
prototypes have been built and tested.
• The manufacturing tolerances need not be tight.
• Less moving parts , hence lubrication required is quite low.
• Design is simple compared to turbo pumps.
8/24/2016 Piston less Pump 16
17. DISADVANTAGES
• They cannot pump to higher pressure than drive gas (area ratio is 1:1)
• They cannot use either a staged combustion or expander cycle.
• A gas generator cycle is also difficult to integrate with the piston
less pump.
• The generated gas must be chemically compatible with both the
propellants.
• This gas generator lowers the Ignition start period of the engine.

18. FUTURE APPLICATION
• Static test and fly pump
in student rocket with
Flometric’s rocket
technology.
• Along with latest low
cost engine designs,
pump will make lunch
systems more safe,
reliable and affordable

19. CONCLUSION
• The most significance of property of Piston less pump that makes
them different from that of turbo pump ,is the absence of piston.
• This is the most unique technique. In this ,no. of rotating parts is very
less as compared to that of turbo pump. Also, it’s installation is very
easy. and moreover, it is light weight than turbo pump. So, it has less
