Abstract:

Two types of turbine engine air inlets are described. Models of these inlets were instrumented with high frequency pressure sensors and turbulence levels were measured in the wind tunnel for various mass flow ratios, angles of attack and sideslip angles. The instrumentation and methods of data reduction and analysis are described. Some results are shown to support the merit of high frequency, non stationary instrumentation. Non stationary data are compared with stationary measurements taken at the same time.
