Abstract : In the last two decades, Air Force has made significant contributions to the development of the ejector technology for thrust augmentation purposes. Initially, Aerospace Research Laboratories at WPAFB undertook a major task of demonstrating that compact, thrust augmenting ejectors could be designed. After ARL successfully demonstrated that by utilizing hypermixing nozzles, thrust augmentation ratio of the order of two could be achieved, Flight Dynamics Laboratory launched a program of conducting preliminary design of an ejector thrust augmented demonstrator aircraft. ARL's work laid the foundation for a systematic study of the ejector application for V/STOL aircraft.
