Abstract:

The propellant and oxidizer tanks of the Gemini B Reentry Control System incorporate thermostatically controlled heaters to maintain their temperature within prescribed limits. Tests were performed to develop a method to verify operation of the thermostats while the tanks are installed in the spacecraft. The tests showed that the thermostats can be cooled to actuation temperature in four minutes or less using cold nitrogen gas or a mixture of Freon 12 and nitrogen. Author
