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.

Aircraft with thrust and lift augmenting airfoil

TL;DR: In this paper, an aircraft is disclosed having a jet engine whose exhaust stream flow rearwardly from above the trailing edge of a main wing of the craft, and having an auxiliary airfoil which is lower than and offset rearwardsly with respect to the wing and acts during takeoff to augment thrust and lift, and during braking and landing to increase drag and lift.

Development of a Circulation Control Wing for UAVs

TL;DR: In this article, the curvature of the trailing edge on a Clark-Y airfoil has been investigated to provide increased lift to a fixed-wing UAV. And the results showed that the smaller Coanda surface configuration is more effective.
