    Abstract:

    In this paper, based on the mature technical system of hydroxyl terminated polybutadiene(HTPB) composite solid propellants, the new energetic material have been introduced for these formulations to obtain plume with less emission and higher combustion efficiency. According to the literature, in order to achieve the low emission of the combustion plume, high-energy compounds such as hexanitrohexaazaisowurtzitane (CL-20) and polynitrogen compounds can be used to partially replace some ammonium perchlorate (AP), whereas the dinitramide Ammonium (ADN) and nitrous oxide (HNF) are expected to completely replace AP in HTPB propellants. More importantly, in order to improve the combustion efficiency of aluminum (Al) powder, aluminum hydride (AlH3), nano-Al or various composite Al powder could be used. In general, the development of new energetic ingredients for HTPB propellants should follow the problem-oriented principle. As a result, it′s better to investigate the characteristics of such novel energetic ingredients, and thereby the practical applications of HTPB propellants could be extended, which may promote solid-power technology in both military and civilian applications.
