Abstract

The invention provides one, and belongs to the technical field of aircraft. In the present invention, foldable wings are designed on both sides of the fuselage, and a set of duct devices are respectively arranged at the head and tail of the fuselage. The duct devices can rotate on the vertical plane. The four groups of rudder surfaces in the duct devices are Cascade-type rudder surfaces, two of which are parallel to the Y axis perpendicular to the fuselage axis in the horizontal plane, and can deflect around the Y axis, and the other two groups are parallel to the Z axis perpendicular to the fuselage axis in the vertical plane, and can rotate around the Z axis Axis deflection, the four sets of rudder surfaces can rotate clockwise and counterclockwise on the X-axis of the fuselage axis. When the wings are folded, they are inside the fuselage. The upper surface and the lower surface of the middle part of the fuselage are respectively provided with curved guide surfaces to reduce the resistance to the middle part of the fuselage. By adjusting the deflection of the four sets of rudder surfaces, the aircraft can be lifted and rudder changed. The invention has a simple structure and can realize the vertical take-off and landing of the aircraft, the ability to hover, and the ability to fly horizontally at 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...
