摘要
由于腹部进气布局导弹进气道和弹体内外流相互干扰,使得此类导弹的气动性能难以计算。为解决初步设计阶段此类导弹的气动计算问题,文中以DATCOM程序为基础,以CFD数值模拟为依据,采用部件组拆方法,发展了一种腹部进气布局导弹的气动力快速估算方法。结果显示,该方法计算速度快、适应性好、精度高,在吸气式导弹初步设计中具有较高的应用价值。
The aerodynamic performance of the ventral inlet configuration missile is hard to predict due to the complex interferences between inlet and the outer flow field. To solve the problem in the conceptual design of the missile, based on DATCOM program and CFD numerical simulation, a method combining component built-up method and CFD-corrected results was developed. The results showed that the method was efficient, adaptive, and highly accurate;it has high application value in conceptual design of air-breathing missile.
