Internal Performance of a Variable Ramp Mixed Compression Intake at Mach 3.05

摘要

Results are presented of an experimental investigation into the performance of a two-dimensional mixed compression intake which featured focussed cowl compression matched to a discrete slot boundary layer bleed system. The tests were conducted at the intake design Mach number of 3.05. The design worked well in a two-dimensional sense, but the losses were exacerbated by three-dimensional viscous effects involving the sidewall boundary layers.
