 note = {In order to obtain the dynamic characteristics of the gimbal system under thrust load, firing tests with 300 kg thrust liquid propellant rocket engine were performed. Major objectives of the test program were as follows, (1) to determine the frequency response of the swivel angle of the engine.  (2) to find out the effect of the fuel and oxygen pipes connected to the engine for the swivel angle of the engine, and the effect of bearing friction of the gimbal system. By a series of tests, the following experimental results were obtained :  (1) Some quantitative measure of the differences between the frequency response of the swivel angle during firing and without firing due to the increase of pressure of the fuel and oxygen pipes, and also due to bearing friction under thrust load, was determined.  (2) The amplitude of vibration of frequency 50 cps. induced on the engine, depend on the back lash of the gimbal system, as well as the servosystem., 資料番号: NALTM0187000, レポート番号: NAL TM-187},
