EM Actuated Cryogenic Valve for Engine Control

*† ‡ § This paper summarizes the activities performed at EADS Space Transportation and Moog Inc., Space and Defense Group, for the development of an electromechanically actuated cryogenic valve with application to upper stage rocket engines. In this joint activity, EADS-ST is providing the cryogenic sleeve valve and Moog is providi ng the cryogenic electromechanical actuator (EMA). This EMA actuated cryogenic valve is identified as an enabling technology for future propulsion systems.
