Vertical take-off and landing aircraft with front wings and rear wings on basis of novel high-lift devices

Abstract

The invention discloses a vertical take-off and landing aircraft with front wings and rear wings on the basis of a novel high-lift devices. The vertical take-off and landing aircraft comprises an aircraft body, wherein a front part high-lift device and a rear part high-lift device are configured correspondingly at the front part and the rear part of the aircraft body; the front part high-lift device as well as the rear part high-lift device comprises a spray pipe and a lift wing; each spray pipe is flat, a flat accelerating section is arranged at the outlet of each spray pipe in a matched manner, and the outlet of each spray pipe directly faces to the suction surfaces of the lift wings. The spray pipe adopted by the vertical take-off and landing aircraft is the flat spray pipe, and the flat accelerating section is arranged at the outlet of each spray pipe in matched manner so as to enable the air flow of the outlets of the spray pipes 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 sections 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, under the combined action of the suction surfaces and the pressure surface, and the larger lift component is obtained.

Description

technical field

[0001] The invention relates to a vertical take-off and landing aircraft with a front and rear wing layout 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 aircra...
