Configuration for vertical take-off and landing system for aerial vehicles
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.read more

On the possibility of using Coanda Effect for Unmanned Aerial Vehicles – a numerical investigation
Boško Rašuo,Nikola Mirkov +1 more
TL;DR: In this paper, numerical results of conceptual design study of an UAV which uses Coanda Effect for lift production are presented, which indicate the ability of manuveuring by creating asymmetric flow patterns which lead to uneven lift production and resulting force with horizontal component necessary for establishing forward flight conditions.
