利用N,N’-二硝基哌嗪改善双基推进剂燃烧性能

Improvement of Combustion Property of Double Base Propellant by N,N'-dinitropiperazine

叙述了含N，N’-二硝基哌嗪（DNP）的双基系推进剂的有关配方及制备，研究了DNP对双基系推进剂能量及燃烧性能的影响，表明DNP使双基系推进剂的燃温下降，比容上升，比冲几乎不变或略有下降，DNP能大幅度降低双基系推进剂的燃速及压强指数。

This paper presents the formulation and preparation method of the double base propellant containing N,N'-dinitropiperazine (DNP) and investigates the effects of DNP on the energy and combustion properties of the double base propellant. Results show that DNP can make burning temperature of double base propellant degreasing and specific volume increasing, but its specific impulse is almost constant or has a little degrease. DNP can sisnificantly degrease the burning rate and pressure exponent of the double base propellant.
