고체추진 로켓모터의 지상연소시험시 발생되는 진동현상에 관한 연구
A Study on Vibration Phenomena occurred in Ground Firing Test of Solid Rocket Motors
초록
Many items, as internal pressure, thrust, temperature, strain, etc. are measured in Ground Firing Test (GFT) of rocket motors. But these items are influenced by various phenomena occurred during propellant combustion. In this study, natural frequencies of motor itself and system(motor+loadcell) on Stand were measured. Also motor responses were measured during burning and analyzed so that the vibration characteristics occurred during GFT and the causes and characteristics of vibration signal appearing on thrust curve were identified.
