Propellant shutoff valves required for the operation of the pulse modulated gaseous hydrogen/gaseous oxygen rocket engines for the Space Shuttle Auxiliary Propulsion System are specified to operate for one million cycles over a ten-year period with zero maintenance, very fast response, very low leakage, and over a wide temperature range. Based on an analytical leakage and wear model, sealing configurations were conceived, sized, and developed. Two prototype valves featuring different components… CONTINUE READING
