This report documents a series of aerodynamic studies carried out jointly by AFAPL and ICFAR personnel in support of the design and development of the AF Aero Propulsion Laboratory Compressor Research Facility CRF. The CRF is a non-return compressor test facility with air extracted from the atmosphere, compressed and then discharged to the atmosphere. In order to reduce compressor power requirements and simulate flight conditions at elevated altitudes, the compressor is mounted in a large tank or text chamber. The tank pressure is regulated with control valves with the compressor itself supplying the exhauster capability. The mass flow rate is measured downstream of the compressor using a series of venturis. The CRF utilizes automated data handling procedures and is capable of simulating some compressor transients. A pilot program utilizing an existing J-85 engine test facility at AFAPL was initiated to explore and develop the measurement technology required in transient compressor testing.
