Double-duct composite wing aircraft

Abstract

The invention provides an aircraft, and belongs to the technical field of aircrafts. The foldable wings are designed on the two sides of a fuselage, a head and a tail of the fuselage are each provided with a ducted device, the ducted devices can rotate on the vertical plane, four sets of control planes in the ducted devices are cascade type control planes, and two sets of control planes are parallel to the Y axis, perpendicular to the axis of the fuselage, on the horizontal plane and can deflect around the Y axis; the other two groups of control surfaces are parallel to the Z axis perpendicular to the axis of the fuselage on the vertical plane and can deflect around the Z axis, and the four groups of control surfaces can rotate clockwise and anticlockwise along the X axis of the axis of the fuselage. The wings are located in the fuselage when folded. The upper surface and the lower surface of the fuselage middle part are respectively provided with a curved flow guide surface to reduce the resistance to the fuselage middle part. By adjusting the deflection of the four groups of control surfaces, the aircraft is lifted and the rudder direction is changed. The vertical take-off and landing aircraft is simple in structure, can realize vertical take-off and landing, and can hover and horizontally fly at a high speed.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a dual-duct compound wing aircraft. Background technique [0002] As we all know, there are two major branches of aircraft, namely fixed-wing aircraft and rotary-wing aircraft. Aircraft belong to the first branch, which can fly horizontally at high speed, but need a runway to take off and land. This means the plane cannot hover in the air, nor can it take off or land vertically. Meanwhile, helicopters belong to the second branch. Although it can take off or land vertically and be able to hover in the air, the limitation of horizontal flight speed compared with airplanes has become a real drawback for it to be difficult for long-range missions. [0003] In the Chinese patent application document CN109263885A, a kind of ducted propeller aircraft is disclosed, comprising: frame, ducted coaxial twin propellers, ducted propeller, ducted body, power system, control system; the fram...

AI Technical Summary

Problems solved by technology

[0005] 1. It is not suitable for both vertical take-off and landing, hovering, and high-speed horizontal flight

[0006] 2. Although the above-mentioned technical solution can realize both vertical take-off and landing and hovering, there is no fixed wing, the maximum flight speed is also low, and the number of propellers is large, and the effective load of the aircraft is low
