Abstract

Kegiatan penelitian yang telah dilakukan sebelumnya telah diperoleh material insuliner berbasis epoksi dan metode aplikasinya pada motor roket case bonded. Hasil penelitian ini juga telah diperoleh bahwa insuliner tersebut dapat direkomendasikan untuk digunakan pada motor roket case bonded yang menggunakan propelan radial burning sehingga perlu dibuktikan. Guna menguji kinerja insuliner tersebut telah dibuat dua unit motor roket case bonded mengggunakan insuliner berbasis epoksi dan satu unit motor roket free standing yang menggunakan insulasi termal berbasis epoksi dan lapisan fiber glass cloth untuk diuji statik. Tiga unit motor roket telah diuji statik. Berdasarkan pengujian diperoleh bahwa insuliner berbasis epoksi yang dibuat dapat berfungsi dengan baik. Kegagalan motor roket case bonded yang kedua tidak disebabkan oleh gagalnya insuliner tetapi oleh proses perakitan motor roket yang kurang sempurna.Kata kunci: Insuliner,Motor roket, Case bonded, Free standing, Radial burning

Abstract

The propellant joints quality of RX 550 rocket motor using segmented HTPB propellant was become a debatable. In static test this rocket motor exploded and the nozzle was broken out at seven second after ignition. To evaluate these propellant joints the propellant installation in rocket motor was discused. The propellant joint strength was tested using Tensilon UTM III-100 test equipment. The rocket motor tube at the propellant joint position were marked and investigated before and after static test. The datas such as thrust and chamber pressure versus time were analyzed for finding the posibility of joints defect. Based on analysis it is found that the propellant joint can work well. The RX 550 rocket motor failure in static test didn’t caused by propellant joints. Key words: Propellant, Propellant joint, Static test
