Flying wing type aircraft with variable wing outer wing sweep back angle and tiltable small wing

Abstract

The invention discloses a flying wing type aircraft with a variable wing outer wing sweep back angle and a tiltable small wing. The flying wing type aircraft with the variable wing outer wing sweep back angle and the tiltable small wing comprises an inner wing leading edge, outer wing leading edges, small wings, outer wing trailing edges, an inner wing trailing edge and elevons; outer wings are arranged on the two sides of an inner wing; the small wings are arranged at the tips of the outer wings; the outer wings and the small wings all adopt flexible skin structures; first acting mechanisms are arranged between the outer wings and the inner wing; and second acting mechanisms are arranged between the small wings and the outer wings. The flying wing type aircraft with the variable wing outer wing sweep back angle and the tiltable small wing has the advantages that higher lift drag characteristic of the aircraft is guaranteed, the reachable maximum flying speed of the flying wing type aircraft is increased, and meanwhile, the drag in each speed stage is reduced so that the aircraft can preferably develop the efficiency on a fighter plane.

Description

technical field [0001] The invention belongs to the field of aircraft and specifically designs a flying-wing aircraft with a variable wing outer wing sweep angle and a tiltable winglet. Background technique [0002] Swept wings are primarily used on modern transonic and supersonic aircraft. The choice of the sweep angle of the outer wing of the double-swept wing plays a vital role in the overall performance of the aircraft; a small outer wing sweep angle is conducive to improving the maneuverability of the transonic aircraft, but when flying at supersonic speed, the lift Smaller, unable to achieve fast flight; large outer wing sweep angle is conducive to achieving supersonic flight and completing defense penetration tasks, but when taking off and landing, the lift force is small, and short-distance taxiing cannot be achieved. The biggest advantage of the aircraft with variable wing sweep angle is that it can change the sweep angle, so that the performance of the aircraft ca...

Problems solved by technology

Aiming at improving the existing flying-wing aircraft, the contradiction between good maneuverability and high speed required for combat flight, and the inability to maintain the drag reduction effect under all circumstances can be achieved. The means of combining the two variant technologies of variable wing sweep angle and tiltable winglet with flying wing aircraft has invented a kind of aircraft that can take into account high-speed and low-speed flight, and realize maneuverability and fast stealth at the same time. A flying-wing aircraft that can effectively reduce drag in different flight stages
