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.

V/STOL aircraft and method

TL;DR: Aircraft apparatus and method capable of V/STOL (vertical, short takeoff and landing) in addition to conventional flight is described in this paper, where induced lift is provided by blowing air over the upper surface of each wing through a duct installed near the leading edge, thus providing suction as well as blowing two fans in series.
