Examined by:Luu; Teri Pham

Separate upper and lower plenums within an aircraft airfoil or a sea hydrofoil conduct fluid under different pressures to nozzle slots from which jets emerge to augment lift in accordance with different travel conditions. Lift is induced by nozzle slot emergence of a primary jet from one of the plenums along a reverse flow path relative to secondary jet outflow from the other plenum. This capability involves angularly adjusted deflection of the primary jet outflow along forward, reverse or vertical directional flow paths from the trailing end of the airfoil or hydrofoil under zero and other different speed conditions by emergence of the secondary wall jet.
