Abstract

The invention discloses a novel large-lift-force vertical take-off and landing aircraft. The aircraft comprises an aircraft body and main wings arranged on the two sides of an aircraft tail of the aircraft body. Each main wing is jointly formed by an inside main wing body and an outside main wing body. Each inside main wing body is a sweep-forward wing, and a sweep-forward angle ranges from 10 degrees to 75 degrees. Two vertical tails are arranged above the aircraft tail of the aircraft body. Canards are arranged on the two sides of an aircraft head of the aircraft body. A rotor wing is arranged above the aircraft body. A power device is arranged between each inside main wing body and the corresponding outside main wing body. An undercarriage is arranged at the lower portion of the aircraft body. By the adoption of the novel large-lift-force vertical take-off and landing aircraft, the flight properties of vertical take-off and landing, the high speed, the long navigation time and the large voyage are considered, the characteristic of a large task load is achieved, and the lift-drag characteristic in the high-speed flight process and the propelling efficiency of a power system are higher than those of a helicopter and those of a tilt rotor, a flight envelope is wider; and meanwhile decoupling is controlled through lift force and horizontal thrust, so that the aircraft is in transition from a low-speed flight state to a high-speed cruising state stably.

Description

technical field [0001] The invention belongs to the field of aircraft design, and in particular relates to a novel high-lift vertical take-off and landing aircraft. Background technique [0002] Vertical take-off and landing aircraft mainly originated from vertical take-off and landing aviation technology, and vertical take-off and landing aviation technology, as the name implies, refers to the aviation technology that aircraft can complete take-off and landing without taxiing. Vertical take-off and landing aviation technology originated in the 1950s. In the world, the United Kingdom, the United States, and Russia have successively adopted this technology on their aircraft carriers. [0003] Aircraft with vertical take-off and landing capabilities do not require special airports and runways, and only need a small flat ground to ensure the safe take-off and landing of the aircraft, which reduces the dependence of the aircraft on airport runways and other facilities, and great...
