An Experimental Investigation of Combining Stealth Device in Air Duct with Turbofan Engine

Wenfeng Li

Abstract

The paper introduces the experimental facilities for combining stealth device in air duct with turbofan engine.How the flow deflector affects the flow field of air duct was ascertained.The fan-shaped flow deflector was made of wave absorption material,its stealth principle is analyzed.The distributing of complicated inlet flow field and the analyses of distortion index are investigated.
