针对当前空空导弹的发展趋势,对基于冲压发动机的第五代空空导弹战术特征进行了分析,给出了空空导弹飞行任务(对空作战和对地打击)。参考“流星”空空导弹,考虑未来内埋远程空空导弹小尺寸、远射程、高速度的基本特点,给定二元三波系进气道、旁侧进气凹腔燃烧室和轴对称拉瓦尔喷管,建立起冲压发动机整机计算模型,完成了冲压发动机(小尺寸,直径167 mm)在高马赫数(3.0~5.0)下的三维数值计算和分析,初步验证了冲压发动机作为未来内埋远程高速空空导弹的可行性。

According to the current development trend of air-to-air missile, the tactical characteristics of the fifth generation air-to-air missile based on ramjet are analyzed, and the air-to-air missile mission (air-to-air combat and ground attack) is given. With reference to “meteor” air-to-air missile, considering the basic characteristics of small size, long-range and high-speed of future embedded long-range air-to-air missile, the calculation model of ramjet is established with two-dimensional three wave system inlet, side intake cavity combustor and axisymmetric Laval nozzle. The three-dimensional three wave ramjet (small size, diameter 167 mm) at high Mach number (3.0~5.0) is completed. The feasibility of the ramjet as an embedded long-range high-speed air-to-air missile in the future is preliminarily verified by dimensional numerical calculation and analysis.
