Active Control of Secondary Flow in Engine Inlets

Abstract

As the next generation of unmanned aerial vehicles (UAV) and unmanned combat aerial vehicles (UCAV) are being developed, the need for highly compact inlet diffusers is increasing quickly. In order to design and evaluate such inlets, additional flow property measurement techniques need to be brought to bear on the situation. The use of pressure-sensitive paint (PSP) and seven-hole pressure probes on these designs will expand the knowledge and understanding of flow properties and behavior involved in highly compact inlet diffusers. The purpose of this thesis is to evaluate the use of PSP and seven-hole pressure probe in evaluating inlet diffusers.
