Method and device for assisted vertical take-off and landing of fixed-wing aircraft

Abstract

The invention discloses an auxiliary vertical take-off and landing method for a fixed-wing aircraft. 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 height; and / or, In the landing stage, the rotorcraft is first used to dock with the fixed-wing aircraft in the air, and then the rotorcraft is used to carry the fixed-wing aircraft to land vertically. The invention also discloses an auxiliary vertical take-off and landing device for a fixed-wing aircraft. Compared with the prior art, the present invention can realize the take-off of the fixed-wing aircraft under the condition of no-slip runway through appropriate minor modification without reducing the load and flight performance of the fixed-wing aircraft and without changing the aerodynamic layout of the fixed-wing aircraft. drop problem.

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...

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
