Configuration E-7 Supersonic STOVL Fighter/Attack Technology Program

The program convering the design and early technology development of Configuration E-7, a supersonic STOVL Fighter/Attack aircraft is described. This aircraft uses the ejector principle to augment engine fan air for vertical lift. The initial design objectives selected in 1980 are listed and discussed. Some design considerations applicable to the propulsion concept and the chosen configuration are mentioned. The test program accomplished thus far, including wind tunnel models plus other test articles and activities is outlined. The program has proceeded without major technological obstacles and a full-scale engine-powered model will soon be ready for test.
