The slot openings are normally closed by spanwise extending flaps which fair into the airfoil contour and when the slots are open cooperate therewith to form individual thrust augmenting ducts. A large number of primary nozzles are provided for injecting high pressure air, derived for example from the bypass air of a conventional turbofan engine, into the ducts.
