A vertical take-off and landing aircraft

Abstract

The invention discloses a vertical take-off and landing aircraft which comprises an aircraft body, wherein wings are arranged on two sides of the aircraft body; tail rod containing bins are embedded into the wings; the upper ends of the tail rod containing bins are connected with power devices; output shafts of the power devices are connected with propellers; telescopic tail rods are arranged in the tail rod containing bins; the lower ends of the tail rods extend out of the tail rod containing bins and are provided with take-off and landing racks; a horizontal tail is arranged between the take-off and landing racks on two sides of the aircraft body; an elevator is arranged on the rear edge of the horizontal tail; tail rod locking mechanisms are arranged at the lower ends of the tail rod containing bins; when the tail rods completely extend out of the tail rod containing bins or retract into the tail rod containing bins, the tail rod locking mechanisms lock the tail rods. The aircraft provided by the invention is simple in structure; the operability, the stability and the economical property of horizontal cruising of the vertical take-off and landing aircraft and the stability of parking of the vertical take-off and landing aircraft are improved.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a vertical take-off and landing aircraft. Background technique [0002] With the development of aviation technology, people put forward more and higher requirements on the speed, energy consumption, convenience and safety of aircraft. For example, the Xplane test plan proposed by DARPA (Administration of Advanced Technology Research) in 2013 requires the hovering efficiency of the vertical take-off and landing vehicle to be no less than 0.75, the lift-to-drag ratio of the level flight to be no less than 10, and the payload rate to be above 12.5%. Although this only represents the needs of an American user, there has already been an upsurge in the development of new vertical take-off and landing aircraft around the world. [0003] Vertical take-off and landing aircraft usually include helicopters, rotorcraft, flapping wing aircraft, tilting rotor aircraft, tail-sit vertical take...
