摘要
比较了不同降速剂在丁羟(HTPB)推进剂、双基推进剂、改性双基推进剂、硝酸酯增塑聚醚(NEPE)推进剂4种类型固体推进剂中的降速效果,并归纳总结了不同推进剂中降速剂的降速机理。HTPB推进剂降速剂研究较多的是(NH_(4))_(2)C_(2)O_(4)和金属盐;普通降速剂和功能降速剂均能降低双基推进剂的燃速;改性双基推进剂以蔗糖八醋酸酯(SOA)研究居多,在2~15MPa范围内,使得推进剂燃速降低2.3~8.12mm/s;在相同的条件下,NEPE推进剂中的复合或双功能降速剂具有较好的降速效果。建议今后降速剂的重点研究方向应集中在以下几方面:开发新型高效降速剂、深入研究复合降速剂、探索含能降速剂以及开展微纳米降速剂的研究。附参考文献53篇。
The burning rate reduction effects of different burning rate inhibitors in HTPB propellant,double base propellant,modified double base propellant and NEPE solid propellants are compared,and the burning rate reduction mechanism in different propellants is also summarized.Modified ammonium oxalate and metal salts are the most studied burning rate inhibitors for HTPB propellant;both ordinary and functional burning rate inhibitors can reduce the burning rate of double base propellant;most of the modified double base propellants are sucrose octaacetate(SOA),the burning rate of the propellant is reduced by 2.3—8.12mm/s over the pressure range of 2—15MPa;under the same conditions,the composite or bifunctional burning rate inhibitor in NEPE propellant has better burning rate reduction effect.It is suggested that the key research directions of the burning rate inhibitor in the future should be focused on the following aspects:the development of high-efficient burning rate inhibitors,the in-depth study of composite burning rate inhibitors,the exploration of energetic burning rate inhibitors and the development of micro-or nano-burning rate inhibitors.With 53 references.
