Pistonless pump



INTRODUCTION:

NASA have developed a Low cost rocket fuel pump which has
Comparable performance to turbopump at 80-90% lower cost. Perhaps
the most difficult barrier to entry in the liquid rocket business is the
turbo pump. A turbo pump design requires a large engineering effort
and is expensive to mfg. and test. Starting a turbo pump fed rocket
engine is a complex process, requiring a careful of many valves and
subsystems.In fact ,Beal ....etc

PISTONLESS PUMPS IN ROCKETS

Presented By:

WHAT IS PUMP
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.

ABSTRACT:
Pistonless pump for rocket has been proved to be the most economical than piston pump or turbopump.
In pistonless pumps, piston is absent. It has very much less rotating parts than that of piston pumps or turbo pumps. So, it has less friction losses and there by it helps to improve the efficiency of the engine considerably.They can be easily installed in the rocket than turbopumps.Also,it reduces the weight of rocket.
This article discusses the working , advantages of p ....etc

A pump without a piston is a type of pump designed to move fluids without moving parts other than three-chamber valves.

The pump contains a chamber having a valve inlet from the fluid to be pumped, a valve outlet - both at the bottom of the pump, and a pressure port at the top of the pump. A pressurant is used, such as pressurised steam or helium, to conduct the liquid through the pump. NASA has developed a low cost rocket fuel pump that has comparable performance to the turbo-pump at the lowest 80-90% cost. Perhaps the most difficult barrie ....etc
