TLDR
In this article, the main wing has an auxiliary wing arranged either above or below in spaced biplane relation with the space between the wings, in combination with suitable end plates, forming a rectangular propulsion duct extending spanwise on each side of a central fuselage.Abstract:
The invention relates to a propulsion system particularly adapted to VTOL and STOL type of aircraft and in which a main wing has an auxiliary wing arranged either above or below in spaced biplane relation with the space between the wings, in combination with suitable end plates, forming a rectangular propulsion duct extending spanwise on each side of a central fuselage. A gas turbine driving an air compressor has the compressed air therefrom delivered through a conduit formed in one of the wings from whence it passes to a series of injection nozzles which inject air into the duct inlet to entrain and mix with atmospheric air drawn into the inlet and which expands in a diffuser portion of the duct to generate an augmented propulsive thrust. The nozzles are housed in streamlined struts or housings extending vertically between the wings and transverse to the duct. One of the wings is provided with an adjustable trailing edge flap for varying the discharge area of the propulsive duct diffuser and the other wing is provided with a flap provided with nozzles at its leading edge and adapted to discharge over the suction surface of the flap and when the flap is depressed downward to cause additional downward deflection of the propulsive duct discharge by "Coanda" effect.read more

High performance forward swept wing aircraft
TL;DR: In this article, a high performance aircraft capable of subsonic, transonic and supersonic speeds employs a forward swept wing planform and at least one first-and second-solution ejector located on the inboard section of the wing.

Boundary layer control system for aircraft
TL;DR: In this article, an improved boundary layer control system is proposed for aircraft wing, where a number of manifolds are located in spanwise arrangement along the wing and serve to conduct the air from the source to a plurality of nozzle penums, each of which includes a pluralityof spanwise-spaced apertures for injecting air into a portion of the boundary layer region.

Aircraft internal wing and design
TL;DR: In this paper, the Coanda effect is used to increase the airflow across the top surface of the bottom wing of an aircraft, and the aircraft can be designed so that it is large enough to carry people and/or cargo, or small enough to be flown as a toy aircraft.
Patent
Internal wing aircraft
TL;DR: In this article, an aircraft having a fuselage provided with an internal duct extending longitudinally therethrough to provide an internal wing for the craft, the internal duct having the forward end open for receiving an air stream therethrough and the aft end thereof open for discharge of the air stream from the aircraft's internal contour being alterable in accordance with required operational conditions for the flight of the craft.

Control flap with fluid jets for aircraft
TL;DR: The possibility of sucking boundary air by slots or orifices in the wings and other parts of an aircraft has been investigated in this article, where it is known that the air in the "boundary layers" of the aircraft exerts a retarding effect by increasing the general drag.
