Analisis kinerja teoritik dan uji statik motor Rx-250/2000 propelan HTPB konfigurasi bintang-7

Uji statik motor roket RX-250/2000 dilaksanakan pada 16 Oktober 1995. Kinerja motor tersebut ditunjukkan dengan parameter-parameter tekanan ruang bakar dan gaya dorong vs waltu dari hasil wji statik. Kemampuan ditunjukkan oleh kurva gaya dorong ys waktu dihitung dari uji statik (21600 kg-sec) lebih rendah dari basil teoritis (22065 kg-sec). Dengan cara yang sama ditunjukkan bahwa secara teoritik tekanan ruang bakar 57 kg/cm° dan gaya dorong 3765 kg sedangkan hasil uji statik tekanan ruang bakar 60 kg/cm? dan gaya dorong 3600 kg. Hasil keseluruhan dapat disimpulkan bahwa kinerja motor dari uji static menunjukkan pensimpangan dari harga teoritil kurang dari 6 %.

Static test of motor RX-250/2000 had been conducted on October 16,1995. Its performance parameters, including chamber pressure and thrust-time curve were recorded. The result showed that the performance, indicated by the area under thrust-time curve, calculated from static test (i.e21600 kg-sec) is a bit lower than the theoritical value (i.e 22065 kg-sec). The same phenomenon is indicated by its chamber pressure 60 kg/cm°, while its theoritical value is 57 kg/cm°. In the other hand the static test thrust 3600 kg is some what lower than its theoritical value 3765 kg. The overall results concludes that the performance parameters measured though static test deviate from the theoritical value by less than 6 %.
