This paper presents some views of a practitioner from the perspective of powered lift in which a substantial proportion of engine thrust is devoted to augmentation of wing lift. As such, control of the boundary layer takes place in rather a macroscopic way due largely to entrainment of secondary flow into a powerful jet or jet sheet. The Augmentor-Wing powered life concept has been the subject of investigation jointly by Canada and the United States since the late sixties. Following extensive tests of a half scale mode inthe NASA, Ames 40' x 80' wind tunnel, a decision was made to design and build a minimum cost flight demonstrator based on the de Havilland Buffalo airframe. This technology demonstrator aircraft first flew in 1972 and subsequently underwent trials at NASA, Ames, accumulating a total of 650 flying hours. Following completion of the NASA trails in 1980, work has continued in Canada covering four main areas of interest: additional flight trials on the technology demonstrator aircraft, propulsion system development, experimental investigation of a new compound supercritical airfoil, and project definition studies.
