Abstract:

Engine and airframe manufacturers as well as United Kingdom research groups investigated the engine/airframe compatibility issues both theoretically and experimentally. Aulehla compiled the main results of these investigations and was able to draw conclusions from those results. Aulehla found that the inlets on most conventional supersonic fighter aircraft generate some sort of swirl. Through the investigations, it was found that bulk swirl could be attenuated using simple solutions such as intake fences. It was found that the attenuation of paired swirl was much less than that of bulk swirl using the intake fences because of the stable nature of paired swirl. Flight testing revealed that engines without IGVs are sensitive to even small changes in the magnitude of counter-swirl.
