Inlet Duct—Engine Airflow Match and Compatibility for Supersonic Aircraft 620300

A record of excellent compatibility with induction systems of all installations has been established by the J79 engine in six air weapons operating at Mach 2 and above. The paper discusses the aspects of steady state matching, dynamic matching, inflow distortion, and compressor design. Studies show that the engine must be evaluated as a component of the propulsion system, and that dynamic matching is at least as important as steady state matching for air breathing engines at Mach 3 and above.
