DEVELOPMENT OF VTOL AIRCRAFT DRIVE FORCES AND AIRCRAFT TO THIS END Russian patent published in 2014 - IPC B64C29/00 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, namely, to VTOL aircraft. proposed method consists in directing of gas jet tangentially to airfoil top convex surface. Outflowing flat pulsating gas jet is formed in transient super sound ejector composed by the system of two inlet channels communicated with constant-area air intake slits atop the airfoil surface, mixing chamber and jet nozzle as discharge slit atop said airfoil. Aircraft comprises airfoil section with top bulged surface. Said transient super sound ejector arranged inside the wing is composed by the set of channels communicating the constant-are air intake slit that makes the cruise inlet and constant-area air intake slit that makes the launch inlet arranged at top point of airfoil section. Airflows are connected in fuel manifold zone while combustion products outflow via slitted nozzle arranged at wing top surface between starting inlet and section trailing edge.

EFFECT: higher efficiency, better aerodynamics.
