Why Ejectors for Aircraft Propulsion-Lift Systems and Where We Stand.

Abstract

The thrust augmentation, lift augmentation and noise reduction characteristics of compact ejectors make them potentially attractive for propulsion lift systems; however in the past, poor thrust augmentation results have negated the other benefits. This report covers the general characteristics of ejectors pointing out what makes them attractive and why only certain types of ejectors are of interest. It reviews the key requirements for high performance thrust augmentation. It also presents a summary of the performance results achieved thus far and proposes some possible applications for various types of V/STOL aircraft. (Author)
