Problems solved by technology

[0004] However, due to the structural characteristics of the rotor-fixed-wing composite aircraft, it requires more auxiliary mechanical structures. These redundant operating surfaces and their associated actuators increase the weight of the aircraft itself, thereby reducing the flight time and range of the aircraft. In addition, Rotor-fixed-wing composite aircraft carries its heave power system and structure all the way during cruising flight in fixed-wing mode. This kind of weight is an invalid load during cruising flight, and the resistance it brings cannot be ignored, resulting in weak load carrying capacity of this type of aircraft. , low flight efficiency

Embodiment Construction

[0025] Aiming at the deficiencies in the prior art, the solution idea of ​​the present invention is to use the rotorcraft to assist the fixed-wing aircraft to perform vertical take-off and / or vertical landing; the rotorcraft carries the fixed-wing aircraft and separates the two planes after vertical take-off, and the fixed-wing aircraft can perform cruise efficiently mission, the rotorcraft can land on standby or perform other tasks; when the fixed-wing aircraft needs to land, use the rotorcraft to accurately dock and capture the fixed-wing aircraft, and form a combination after being restrained and fixed for vertical landing.

[0026] The fixed-wing aircraft assisted vertical take-off and landing method proposed by the present invention is specifically as follows: in the take-off stage, the rotor aircraft is used to carry the fixed-wing aircraft to take off vertically, and the rotor aircraft is separated from the fixed-wing aircraft after the take-off reaches a predetermined he...

Abstract

The invention discloses an auxiliary vertical take-off and landing method for a fixed-wing aircraft, and the method comprises the steps: carrying the fixed-wing aircraft to vertically take off at a take-off stage through a rotor aircraft, and enabling the rotor aircraft to be separated from the fixed-wing aircraft after the rotor aircraft takes off to a preset height; and / or in the landing stage, firstly, the rotor craft is used for being in butt joint with the fixed wing craft in the air, and then the rotor craft is used for carrying the fixed wing craft to vertically land. The invention further discloses an auxiliary vertical take-off and landing device for the fixed-wing aircraft. Compared with the prior art, on the premise that the load and flight performance of the fixed-wing aircraft are not reduced and the aerodynamic layout of the fixed-wing aircraft is not changed, the fixed-wing aircraft can take off and land under the condition of no taxiing runway through proper tiny modification.

Description

technical field [0001] The invention relates to a method and a device for assisting vertical take-off and landing of a fixed-wing aircraft. Background technique [0002] With the continuous development of aircraft technology, the performance requirements of aircraft are getting higher and higher in both military and civilian fields. An important capability required by today's military is the ability to rapidly transfer combat troops and military equipment. Conventional fixed-wing aircraft have fast flying speed and long cruising distance, and can realize rapid transfer of troops. However, conventional fixed-wing aircraft have higher requirements for take-off and landing conditions. Schemes for helicopters or ground vehicles. [0003] In order to take into account the advantages of the above-mentioned aircraft, the concept of a rotor-fixed-wing composite aircraft was proposed, which includes tilt-rotor aircraft, vertical take-off and landing fixed-wing aircraft, etc. It ha...
