Twin-duct composite tail vane vertical take-off and landing aircraft

The invention relates to a twin-duct composite tail vane vertical take-off and landing aircraft which comprises an airframe, force bearing wings, ducts, a composite tail vane and landing gears. The ducts are connected with the airframe by the force bearing wings and are bilaterally and symmetrically configured; the force bearing wings are raised wings with thin-wall structures; one end of the composite tail vane is connected with the lower part of the airframe, and the other end of the composite tail vane is of a plane fin-shaped structure; a shock pad is arranged at the middle part of the composite tail vane; a proper angle is formed between the plane fin-shaped structure of the composite tail vane and the cross-sectional plane of the airframe; the small ducts with propellers are arranged at the middle part of the composite tail vane; and the landing gears are symmetrically configured at both sides of the airframe. On the basis of the scheme, the aircraft can vertically take off or land without being limited by the place, can hover and circle, is flexible to operate, not only can fly at a low altitude and at a low speed, but also can fly at a high altitude and at a high speed, has high flying efficiency, low flying noise and good concealment, can be used for executing tasks of carrying, reconnoitring, monitoring, attacking and the like, and has a high application value.
