J52-P-8 Engine Compressor Stall Margin Acceptance Tests

摘要

Two J52-P-8 engines were tested in a sea level cell to develop a method for determining acceptable compressor stall margin. One engine had good stall margin; the other was a 'stall-reject' based on ground static 'Bodie' tests in an A-4 aircraft. Tests were limited to steady-state calibrations, inlet distortion, and power extraction; accelerations, decelerations, and 'Bodies' with standard and enriched fuel schedules. Both engines had acceptable uninstalled steady-state and transient stall margin and steady state distorted inlet stall margin. (Author)
