AN EXPERIMENTAL FEASIBILITY STUDY OF A CRYOGENIC FLUID PISTON PUMP OPERATED BY A LINEAR OSCILLATORY ACTUATOR INSTALLED IN A CRYOGENIC LIQUID TANK

摘要

A cryogenic fluid piston pump operated by the LOA was design, build and experimentally studied for the feasibility of the application for a LH_2 pump. It is found that it is very difficult to realize the pump for LH_2 unless the efficiency of the linear oscillation is improved to a great extent in addition to a good design of the cooling system.
