Static and Dynamic Seals Used on Rocketdyne Engines 670563
This review paper describes typical sealing concepts and materials used throughout the propellant feed systems and pneumatic and hydraulic controls systems of liquid-propellant rocket engines. Seal performance data and detailed descriptions are not presented because of security and proprietary regulations. Emphasis is placed on the sealing concepts utilized to compensate for the extremes of temperatures, pressures, flowrates, and active chemical environments found in liquid-propellant rocket engines.
