PISTONLESS PUMP FOR ROCKET

PISTONLESS  PUMP FOR ROCKET

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 pistonless pump over turbopump. Pistonless pumps are 80-90%  economical  than  that  of  piston pump or  turbo pumps.Nasa has manufactured such kind of pump and tested it actually,and they found it works conveneiently.
