Measurement of Turbine Engine Transient Airflow in Ground Test Facilities

Abstract

Transient airflow is a primary parameter required to evaluate propulsion system component matching, stability and control, and transient engine performance. Development and verification of techniques to calculate turbine engine transient airflow performance have been a difficult, long-term problem. In this study a turbine engine transient airflow simulator was developed and used to evaluate candidate transient airflow measurement systems. Design criteria and analysis procedures are presented for an engine inlet bellmouth and engine subsonic venturi transient airflow measurement system. The recommended systems have nominal transient airflow measurement uncertainties of 1 percent.
