冲压发动机在未来远程空空导弹的分析和仿真研究

Analysis and Simulation of Ramjet in Future Long-range Air-to-air Missile

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.
