| 摘 要： | 初步设计了粉末火箭发动机,并以Mg粉作为燃料、CO2作为氧化剂进行了点火试验.研究结果表明,在一定的压强和温度下,利用空气与Mg粉的燃烧放热可成功引燃Mg粉/CO2,且在关闭空气后达到自持燃烧;燃烧室壁面沉积较多,主要以MgO为主,还有一部分未燃烧的Mg;通过该试验验证了Mg粉/CO2粉末火箭发动机方案的可行性.

| Abstract: | A powdered rocket was preliminary designed,with Mg powder as fuel and CO2 oxidant for firing test.The results show that powder fuel can be rapidly ignited with air under certain pressure and temperature.And after air supplying was stopped,combustion of Mg/CO2 sustained.Most of deposition on chamber wall was white MgO,and some is unburned Mg.This test may verify the feasibility of Mg/CO2 powdered rocket motor. |
