Connecting structure for lift supporting beam of vertical take-off and landing aircraft

Abstract

The invention discloses a connecting structure for a lift supporting beam of a vertical take-off and landing aircraft, the vertical take-off and landing aircraft comprises wings arranged above a fuselage, a propulsion propeller positioned at the tail end of the tail of the fuselage, horizontal tails arranged on two sides of the tail of the fuselage, and an undercarriage positioned below the fuselage, the lower portions of the wings located on the two sides of the fuselage are each connected with a lifting force supporting beam extending in the direction parallel to the axis of the fuselage, the front end and the rear end of each lifting force supporting beam are each provided with a motor cabin, each motor cabin is provided with a pair of coaxial reverse propeller lifting force propellers, and the lifting force supporting beams are detachably connected to the lower portions of the wings. According to the aircraft, a conventional layout is adopted, the lift force supporting beams can be conveniently and integrally detached from the wings, so that the aircraft can be converted into a common aircraft, the lift force structure can be conveniently and integrally detached to be conveniently returned to a factory to be overhauled, and the lift force supporting beams can be conveniently clamped and mounted below the wings.

Description

technical field [0001] The invention relates to a vertical take-off and landing aircraft, in particular to a connecting structure for a lift support beam of the vertical take-off and landing aircraft. Background technique [0002] US 5839691 A discloses a vertical take-off and landing aircraft, the aircraft has no wings in the traditional sense, the nose is provided with canards, the tail is a T-shaped tail, and an engine is installed at each end of a tiltable support arm in the middle As well as the propeller, the vertical take-off, landing and flight of the aircraft are realized by the mechanical mechanism driving the deflection of the support arm. The aircraft of the prior art requires a cumbersome mechanical mechanism to drive and deflect, which not only occupies a large amount of airframe space, but also has complex structure and control and low reliability. [0003] US 4789115 A discloses a conventional layout aircraft that can take off and land vertically, which incl...

AI Technical Summary

Problems solved by technology

The electric drive aircraft of this prior art requires a total of eight independent vertical take-off and landing motors and two horizontal propulsion motors, the weight of the motors is very large, and the driving efficiency is not high. maintain very little flight time

In addition, the aircraft does not adopt a conventional layout, the aerodynamic structure is complex, and the reliability is also poor.
