本文介绍了L8飞机进气道几何参数的选择并对进气道的地面吸气试验和M=0.5～0.8的风洞试验结果作了初步分析。 L8进气道地面吸气试验结果和M=0.5～0.8风洞试验结果表明,L8飞机的进气道性能及其与CJ610—8B、CJ610—8A发动机相容情况,均属良好。
This paper introduces the selection of the geometric parameters of the L8 air intake and makes a preliminary analysis of the air intake test and the wind tunnel test of M = 0.5 ~ 0.8. The results of air intake test on L8 inlet and M = 0.5-0.8 wind tunnel test results show that the inlet performance of L8 aircraft and its compatibility with CJ610-8B and CJ610-8A engines are good.
