摘　　要：流量系数在小型航空发动机高空模拟试验的空气流量计算中十分关键。建立了流量管模型,通过数值计算获取流量管各截面的流场分布,对比另外试验与数值模拟的总、静压分布和流量系数,结果与高空模拟试验进气空气流量测量结果一致。Flow coefficient of air flow calculation is crucial for the small aero-engine in ATF（ altitude test facility）. The model of air flow tube is constructed by numerical simulation method in ATF, as well the flow field distribution of every circle section of the air flow tube can be obtained. The distributions of total and static pressure obtained by numerical simulation are compared with the test data, the comparing results illustrate that they are consistent.
