Servo-Stabilization of Low-Frequency Oscillations in a Liquid Bipropellant Rocket Motor [PDF]

, 1953
The recent work of H. S. Tsien concerning the servostabilization of rocket motors is extended to the liquid bipropellant rocket motor. It is shown that by use of a feedback system containing a device to sense the combustion chamber pressure, a suitably ...
