【摘要】 研制了一种新型的含EM503的PU复合麦撒推进剂,它在4.90～9.66MPa压强范围内产生麦撒燃烧。其麦撒区压强指数为-0.29。从目前报道看来,这是我国第二种复合麦撒推进剂,也是首次在中燃速(约7.2～7.9mm/s)下获得的复合麦撒推进剂。更多还原

【Abstract】 A new type of polyurethane composite mesa propellants with the abbitive of EM503 has been developed. The propellant burns with plateau and mesa effect in the pressure range of, 4.90-9.66MPa. Its pressure exponent is-0.29. According to the literature available, this is the second kind of composite mesa propellants with middle burning rate (about 7.2-7.9mm/s) for the first time in China.更多还原
