Pengujian dan Analisis Kekuatan Sambungan Propelan Konfigurasi Silinder Pada Roket RX 150-1200 - LPN

TThe rocket motor RX 150-1200-LPN which used a propellant joint with hollowconfiguration was failure on static test. The joint strength and a standard rocket motorwith many propellant joints had been tested using JANAF method to investigate the contribution of propellant joint in the rocket motor failure. The static test data of both rockets motor RX 150-1200-LPN and a standard rocket motor were analyzed. It was obtained that the propellant joint strength was higher than the propellant tensile strength,i.e 5.31 kg/cm2 and the rocket motor RX 150-1200-LPN failure was not caused by the propellant joint.
