Abstract

Wind tunnel testing of air intakes of high-speed models is a challenging technical problem. The airflow through the model is required to be accurately simulated during the wind tunnel tests to assess the intake performance parameters such as total pressure recovery, engine face total pressure distortion and the intake instability/buzz phenomenon. Accurate metering and control of duct flows can be achieved by maintaining choked flow through a regulating valve located at the duct exit. This paper describes the choking valve and its use in wind tunnel inlet-airframe models and discusses the instrumentation and control requirements. Emphasis is placed on experimental results obtained from a electrically actuated plug which controls the critical flow area at the downstream end of the intake model. Results of calibration carried on three mass flow control devices are presented.
