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

Dirigible of no rudder face structure
Liu Yang,Teng Yanmei,Wang Lei +2 more
Abstract: The utility model belongs to the technical field of the aircraft, concretely relates to dirigible of no rudder face structure, including the hull, the hull bilateral symmetry is equipped with vector advancing device, and a drive arrangement on every vector advancing device all includes y axle bull stick, z axle bull stick and is fixed in the hull, a drive arrangement are used for driving y axle bull stick and rotate along self the central axis, and the the central axis of y axle bull stick is perpendicular with central line on the hull length direction, fixed mounting has the 2nd drive arrangement on the y axle bull stick, and the the central axis of the 2nd drive arrangement's output shaft is perpendicular with the the central axis of y axle bull stick, Z axle bull stick vertical fixation is on the 2nd drive arrangement's output shaft, and z axle bull stick is kept away from and is installed the power propeller on the 2nd drive arrangement's the tip. The beneficial effects of the utility model are that: increased the vectored thrust, thrust control is nimble, the simple structure of no rudder face, can realize when hovering or speed fly before when very little, move back fly, action such as liter, original place decline, pivot turn on the original place.
