Double vector propeller rotor/fixed wing compound vertical take-off and landing aircraft

Abstract

The invention discloses a double-vector-propeller rotor / fixed wing combined type vertical take-off and landing aircraft and belongs to the technical field of aviation aircraft design. The aircraft is composed of a special-shaped rotor, wings, vector propellers, an aircraft body and tail wings. In the vertical take-off and landing process, main lift force is provided through the special-shaped rotor, the thrust directions of the two vector propellers on the tail wings are left and right in the horizontal direction, and transverse thrust is provided so as to balance the reverse torsion of the special-shaped rotor. In the process of conversion transition from a vertical take-off and landing mode to a flat flying mode, the two vector propellers horizontally deflect by 90 degrees backwards to generate forward thrust, and the lift force is gradually provided through the wings. The aircraft has the vertical take-off and landing capacity and the high-speed flat flying capacity at the same time, and the two modes can be switched in the air. The flat flying speed, the voyage and the endurance are improved by about 50% compared with those of a conventional helicopter. The larger operation range and the higher operation capacity are achieved, and the helicopter can be replaced with the aircraft in future.

Description

technical field [0001] The invention relates to a dual-vector propeller rotor / fixed-wing composite vertical take-off and landing aircraft, which not only has the same vertical take-off and landing and air hovering capabilities as a helicopter, but also can fly at a high speed like a fixed-wing aircraft, and belongs to aviation aircraft Design technology field. Background technique [0002] At present, the outstanding feature of helicopters is that they can perform low-altitude (a few meters from the ground), low-speed (starting from hovering) and maneuvering flight with the same nose direction, especially vertical take-off and landing in small areas. However, there are speed obstacles in helicopters, and high-speed flight cannot be achieved. [0003] The composite vertical take-off and landing aircraft layout enables the aircraft to not only obtain the excellent performance of flexible maneuvering flight at low altitude and low speed and the excellent performance of vertica...

AI Technical Summary

Problems solved by technology

[0005] 1. The conversion control of vertical take-off and landing aircraft based on tilt rotor technology is complex

[0006] 2. The rotor of vertical take-off and landing aircraft based on stalled rotor technology is the main load-bearing component in the level flight mode, and the rotor generally has a relatively large span, and the overall structural stiffness is lower than that of a general fixed wing surface, which is easy to fly when the flying speed is fast. Flutter and other aeroelastic problems occur, which is not conducive to high-speed flight
