摘要
提供的结果来自飞机进气道的设计和性能研究,分析所用的数据来源于进气道模型风洞实验和CFD数值模拟。通过对进气道在机身两侧、翼下、机身下等布局的进气道性能对比,评估了机体对进气道的干扰影响。借助于数值模拟技术,得出进气道进口前流场特性。通过对进气道出口总压的测量和进气道进口波系及喉道处流动的数值模拟计算,归纳出进气道出口平均总压恢复系数和图谱的趋势。
This paaer presents selected results from several investigations of ari inlet design and performance. Diagnodtic data are from airfame-inlet model wind tunnel tests and CFD simulations. Several possible air-frame-inlet configurations are presented and inlet performance levels associated with various forebody shapes and integration techniques such as side-mounted, wing-shielded and fuselage-shielded are compared to assess air-frame interference effects. Examinations of upstream airfame flow fieds and inlet throat local flow with aid of CFD and total pressure surveys at the compressor face are used to explain trends of total pressure recovery and flow fied contour maps.
