Configuration for vertical take-off and landing system for aerial vehicles

Andrei Evulet
TLDR
In this article, a vehicle is coupled to a main body and a fluid generator, and at least one fore and one tail conduit are fluidly coupled to the generator and the primary airfoil element.
Abstract
A vehicle, includes a main body. A fluid generator is coupled to the main body and produces a fluid stream. At least one fore conduit and at least one tail conduit are fluidly coupled to the generator. First and second fore ejectors are fluidly coupled to the fore conduit, coupled to the main body and respectively coupled to a starboard side and port side of the vehicle. The fore ejectors respectively comprise an outlet structure out of which fluid flows. At least one tail ejector is fluidly coupled to the tail conduit. The tail ejector comprises an outlet structure out of which fluid flows. A primary airfoil element is coupled to the tail portion. A surface of the primary airfoil element is located directly downstream of the first and second fore ejectors such that the fluid from the first and second fore ejectors flows over the such surface.

Rocket vehicle thrust augmentation within divergent section of nozzle

TL;DR: In this article, a supersonic nozzle of continuous curvature is used to augment the thrust of a single engine by causing secondary combustion to occur in an annular region of the combustion that complements the primary combustion gas passing through the nozzle and maintaining a wall pressure that is greater or equal to the ambient pressure at low altitudes.

Control of an aircraft as a thrust-vectored pendulum in vertical, horizontal and all flight transitional modes thereof

Thomas Sash
TL;DR: In this article, an improved aircraft includes a thrust source, a wing, and a boom functioning as a free lever and having a distal end upon which the thrust is acting and a proximal end about which the boom is freely rotatable to balance forces acting on the proximal and distal ends of the boom.
