Abstract

Hydroxyl terminated polyether(HTPE) propellants have been developed recently as possible replacements for HTPB/AP propellants currently used in a number of tactical rocker motor. As analyzing friability of HTPE and HTPB propellants in this study, the following results could be derived. The friability of the tested propellants depended on its binder contents, mechanical property, and burning rate. It was decreased as burning rate was lowered and toughness was increased.

Hydroxyl terminated polyether(HTPE) 추진제는 전술용 모터에 현재까지도 적용되고 있는 HTPB/AP 추진제를 대체할 수 있는 추진제로서 최근에 개발되고 있다. 본 연구에서는 HTPE와 HTPB 추진제에 대한 파쇄성 시험을 수행하고 그 결과를 분석하였다. 추진제의 파쇄성은 바인더함량, 기계적 특성 및 연소속도에 의해 영향을 받았으며 연소속도가 증가할수록 기계적 인성이 낮아질수록 파쇄성은 증가하는 경향을 보였다.
