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.

Method and system for flow control with fluidic oscillators

TL;DR: In this paper, an array of fluidic oscillators (4, 6, 8) is used to carry an oscillating flow of the fluid and includes a throat (12), an input port (14) connected to the throat, two control ports (16, 18), and two output ports (22, 24) extending from the throat.

Jet nozzle having centerbody for enhanced exit area mixing

TL;DR: In this paper, the longitudinal axis of the center body is coaxially aligned with the nozzle and the centerbody has a free end portion shaped to create vortices in exhaust exiting the exit area to enhance mixing action in the exhaust and reduce exhaust noise while augmenting thrust.

Vorticity cancellation at trailing edge for induced drag elimination

John L. Loth
TL;DR: In this paper, different methods are disclosed for upper and lower surface boundary layers to cancel their opposing vorticity upon shedding from the trailing edge, thereby eliminating wake vorticty, induced drag and associated noise.
