一引言从六十年代以来,国外就对双推力发动机进行了充分的究研,并开始在空—空导弹上应用。根据不同射程、作战目标、发射条件等战术要求,有单(燃烧)室和多(燃烧)室的,固体的和混合(固体与冲压)式的双推力发动机。例如,法国的空—空导弹“马特拉”R·530使用单室双推力发动机,七十年代的具有较先进性能的美国空—空导弹“麻雀”AIM—7F I. INTRODUCTION Since the 1960s, foreign countries have conducted thorough research on double-thrust engines and begun to apply them on air-to-air missiles. According to the tactical requirements such as different range, operational targets and launching conditions, there are single (combustion) chamber and multi-combustion chamber, solid and mixed (solid and punching) double thrust engine. For example, the French air-to-air missile “Matera” R · 530 uses a single-chamber double-thrust engine, the more advanced American airship-air missile “Sparrow” AIM-7F
