进气道的设计好坏,通常按照进气道性能的特性参数的比较、阻力的大小以及重量、成本的比较结果来衡量。在进行气动设计考核时,需要考核在进气道设计的各个工况下,流场畸变是否足够小、气流是否发生了分离、喉道马赫数是否超过了限制马赫数、总压恢复系数是否足够高等参数。
Inlet design is good or bad, usually according to the characteristics of the inlet port performance parameters, the size of the resistance and weight, cost comparison to measure. In the aerodynamic design assessment, the need to assess the inlet design of the various conditions, the flow field is small enough distortion, air separation has occurred, the throat Mach number exceeds the limit Mach number, the total pressure recovery coefficient is sufficient Higher parameters.
