Dump Diffuser Inlet Test Program.

Abstract

In an investigation of variable geometry inlets and nozzles for application to integral rocket ramjet engines, one of the inlet concepts included a variable ramp which produced a discontinuity in the diffuser region unless a trailing flap was used. The purpose of the program described herein was to evaluate the effect of this discontinuity and provide information for determining whether or not the added complexity and weight of a trailing flap would be required to obtain acceptable inlet performance. The approach undertaken was an experimental program in the Mach 3 wind tunnel with an inlet model incorporating a variable dump diffuser. The model was designed with interchangeable components to provide numerous configurations.
