Model Induction Test Facility Capability for Testing Turbofan Engines

Abstract

The objective of this model study was to determine the potential for testing very large thrust, high-bypass-ratio, turbofan engines at conditions simulating flight Mach numbers of 0.4 to 0.6, sea level, by use of a jet pumped air supply system. The simulation of low altitude, subsonic operation of a large, high-bypass-ratio, turbofan engine in ground test facilities requires extremely large airflows. This airflow, even at relatively low pressure, cannot be provided by existing test facilities for engines having thrust levels of 60, 000 to 100,000 lbf. The jet pumped air supply is therefore a very attractive potential facility.
