Vertical take-off and landing tailstock type coaxial propeller-reversing tailless layout aircraft

Abstract

The invention discloses a vertical take-off and landing tailstock type coaxial propeller-reversing tailless layout aircraft consisting of a fuselage, wings, vertical empennages and a power device; the head of the fuselage is provided with the power device, and a rotating shaft of the power device and the axis of the fuselage are located in a same straight line; both sides of the fuselage are provided with the wings, the upper side and the lower side of the tail part of the fuselage are respectively provided with the vertical empennages, and the central lines of the upper vertical empennage and the lower vertical empennage and the axis of the fuselage are located in a same vertical plane; the trailing edges of the wings are provided with elevons, and the trailing edges of the vertical empennages are provided with rudders. The power device is periodically variable pitch coaxial inversion dual rotor wings, and the rotating directions of the front rotor wing and the rear rotor wing in the coaxial direction are opposite. Five supporting points are formed together by wing tips of the wings, wing tips of the vertical empennages and the tail end of the fuselage; in a stopping state, the five supporting points make the aircraft vertically upwards docked on the ground; the vertical take-off and landing response speed of the aircraft is fast, and the aircraft has good handling stability and wind resistance.

Description

technical field [0001] The invention relates to a vertical take-off and landing aircraft, in particular to a vertical take-off and landing tail seat type coaxial reverse propeller tailless layout aircraft. Background technique [0002] Air vehicle design experts and researchers have been trying to design a vehicle that can take off and land short distances or vertically. To solve the problems that fixed-wing aircraft are limited by the take-off and landing site and the tilt-rotor aircraft has the defects of slow flight speed and short endurance time, as well as the problems of low control efficiency and poor wind resistance of the existing tail-sitting vertical take-off and landing fixed-wing unmanned aircraft . [0003] At present, in practical applications, unmanned aerial vehicles are generally divided into two types: fixed-wing aircraft and rotary-wing aircraft. Although conventional fixed-wing unmanned aerial vehicles have the characteristics of fast speed, long range ...

AI Technical Summary

Problems solved by technology

Its shortcoming is that during the vertical take-off and landing and hovering stages, under the action of the propeller slipstream, the control moment is generated by the deflection of the aerodynamic rudder surface, the control efficiency is low, and the wind resistance is poor.
