摘要
针对飞机飞行高度增加时风斗进气冷却效果的变化规律这一问题。采用数值模拟和试验相结合的方法进行研究。结果发现,在发动机状态相同时,短舱内各测点温度随飞行高度的增加而增加,表明了飞行高度增加,风斗进气的冷却效果会变差。
The cooling effect of air flow inlet the vent scoop changes when the altitude increased,numerical and experimentation means are used in this article.As the result,temperature of each point in the cabin increased with altitude when the engine in the same state.Which means that the cooling effect of air flow inlet the vet scoop worse when the altitude increased.
