Abstract
Bipropellant reaction control systems require unique propellant control valves. The response time of attitude control rockets for space vehicles is a function of the valve response. The minimum obtainable impulse bit is significantly influenced by the propellant valve characteristics.
This paper presents design considerations for pulse operated bipropellant control valves and gives design solution to these problems. Four essential design parameters are considered; these are: reliability, performance, material compatibility, and weight. Reliability is obtained by simplicity of design. The primary performance requirements are fast response, zero propellant leakage, simultaneous operation of fuel and oxidizer metering, and contamination tolerance. Valve weight is minimized through use of a torque motor. Suitable materials are carefully evaluated for compatibility with the propellants, while maintaining a structurally sound unit.
