Abstract

In U.K. patent 2229408 Boeing of Canada Ltd describes a thrust deflector system for VSTOL aircraft. The system consists of a number of spaced‐apart, downwardly facing openings arranged along the bottom of the fuselage. The openings are fluidly connected with an outlet of the aircraft engine so that the pressurised gas from the aircraft engine is discharged through the openings and away from the fuselage in discrete spaced‐apart jets. Each opening has thrust vectoring flaps and end plates. Vents allow air to be drawn from the engine bay into the spaces between the jets when the latter are operative, to reduce “suck‐down” of the aircraft.
