Abstract:

The usefulness of Boundary-Layer Control B.L.C. at the knee of a trailing-edge flap, over the wing nose close to the leading edge or at the knee of a leading-edge flap is first noted. Various methods of providing B.L.C. are outlined, comprising slot blowing, slot suction, area suction, inclined air-jets, and speciallydesigned aerofoil shapes. The aerodynamic aspects of slot blowing over trailine-edge flaps and the wing nose are then examined in detail, and both slot suction and area suction are also considered. The associated pratical design features required for good performance are discussed and some flight-handling implications are mentioned. Autor
