Research on Distortion Characteristics of Aircraft Engine Inlet Distortion Generator
The numerical simulation was conducted on an aircraft engine inlet distortion generator,obtained distortion index under different flow condition,and a detailed comparison with the test results.It is showed that there are some differences in numerical simulation and experimental of distortion index,but the distortion index trends coincide.The flow field after distortion generator showed that there are strongly blend in the upstream region of 0.65D,the blend substantially weakened downstream of 0.65D.In the region of 0.65D to 1.55D,the distortion generator can generate stable distortion airflow.
