Pistonless Pump For Rocket Epub

A positive displacement pistonless rocket fuel pump uses two pumping chambers 23 Nov Abstract · Full-Text PDF · Full-Text HTML · Full-Text ePUB. NASA have developed a Low cost rocket fuel pump which has Comparable performance to turbopump at % lower cost. Perhaps the most difficult barrier to. The pistonless pump is similar to a pressure fed system, but instead of One chamber is pressurized, and fluid is carried to the rocket engine.

One main pistonless pump for rocket and one auxiliary chamber, less weight than two chambers of equal size Pump fits in tank, simplified plumbing Concentric design maintains balance. Model has been built and tested patent pending Animate diagram 7 Advantages Much lighter than pressure fed system at similar cost. At one to two orders of magnitude lower engineering and manufacturing cost than turbopump.

Low weight, comparable to turbopump. No fuel used during spool up. Pistonless pump - Wikipedia Can be run dry.


No minimum fuel requirement. Less than 10 moving parts. Inexpensive materials and processes. The outlet and pressurant valves are closed.

The inlet valve closes, the outlet and pressurant valves open. This performance is similar to state of the art gas-generator turbopump technology. This system would require a supply of gaseous or liquid Helium which would be heated by a heat exchanger mounted on the combustion chamber before it was used to pressurize the fuel, as in the Ariane rocket..

The volume of gas required would be equivalent to a standard pressure fed design, with a small additional amount to account for ullage in the pump chambers.

The rocket engine itself could be a primarily ablative design, as in the NASA Fastrac, scorpious rocket or in recent rocket engine tests. This pump has the potential to reduce the cost and increase the reliability of rocket fuel pumps by a factor of 20 to As shown in the above diagram , two cylinders are there , filled with the fuel from the main tank.

This main tank is emptied in these two cylinders, these cylinders are pressurized by the high pressure tank,as shown. The high pressure tank pressurizes one cylinder of high pressure,as shown,as soon as the cylinder is emptied , it is vented, again it gets filled up from the main tank. The same cycle reapeats for the second cylinder.

As one cylinder supplies the fuel other has enough time to refill. Next More Seminar Topics: Are you interested in this topic.
