Dish-shaped vertical take-off and landing aircraft based on a new type of high-lift device

Abstract

The invention discloses a vertical take-off and landing aircraft in saucer-shaped arrangement and based on a novel high-lift device. The vertical take-off and landing aircraft comprises lift wings, a spray pipe, an engine, suction surfaces and a pressure surface, wherein the outlet of the spray pipe directly face to the suction surfaces of the lift wings. The spray pipe adopted by the vertical take-off and landing aircraft is a flat spray pipe, and a flat accelerating section is arranged at the outlet of the spray pipe in matched manner so as to enable the air flow of the outlet of the spray pipe to further expand and accelerate, and eject out from a flat outlet section at high speed, meanwhile, the exhaust jet stream discharged by the flat accelerating section directly faces to the suction surfaces of the lift wings to enable the area of the suction surfaces of the lift wings to be larger, and under the combined action of the suction surfaces and the pressure surface, the larger lift component is obtained.

Description

technical field [0001] The invention relates to a dish-shaped layout vertical take-off and landing aircraft based on a novel high-lift device. Background technique [0002] Conventional fixed-wing aircraft have high requirements on the runway during take-off and landing, and it is difficult to achieve vertical take-off and landing; helicopters can achieve vertical take-off and landing, but the helicopter has a high-speed rotating rotor, and the speed of the blade at the tip of the wing is faster, which will cause the wing The sharp vortex, the asymmetric shedding of the turbulent vortex of the propeller blade wake, produces periodic impact on the aircraft body, the propulsion efficiency is low, the safety is poor, the structure is complex, the maintenance is difficult, and the comfort of passengers is also poor. During the entire flight, strong aerodynamic noise will be generated, which will seriously interfere with the environment inside and around the aircraft. Contents ...
