Split type linked wing layout aircraft

Abstract

A split type linked wing layout aircraft comprises a main wing, the main wing is a double-sweepback flying wing, a sailboard type wingtip winglet is arranged at each of wing tips of the two sides of the main wing, two empennage connecting rods are symmetrically arranged on the upper surface, close to the rear edge, of the middle section of the main wing, the empennage connecting rods are hollow variable-section straight rods, and a power device is arranged at the tail of the middle section of the main wing. The trailing edge of the wingtip of the main wing is provided with a flaperon rudder, the linked wing is a forward swept wing and adopts a symmetrical wing type, one end of the linked wing is fixedly connected with the top end of the wingtip winglet, the other end of the linked wing is fixedly connected with the top end of the V-shaped empennage, the trailing edge of the linked wing is provided with an elevator, the bottom end of the V-shaped empennage is fixed on an empennage connecting rod, and the trailing edge of the V-shaped empennage is provided with a rudder. The closed structure formed by mutually connecting all the parts improves the overall structural strength of the aircraft, the pneumatic flutter problem of the aircraft during high-speed flight is solved, direct force control of the aircraft with the split-type linked-wing layout is achieved through the split-type linked-wing layout form and the single-engine power arrangement higher than the main wings, and the flight quality of the aircraft is improved.

Description

technical field [0001] The invention belongs to the technical field of aircraft design, and in particular relates to a split-type aircraft with wing layout. Background technique [0002] The flying-wing layout aircraft adopts wing-body fusion technology, cancels the horizontal tail and vertical tail of the traditional aerodynamic layout, and looks like a lifting surface as a whole. This aerodynamic layout can improve the lift-to-drag ratio and reduce the radar reflection area, while effectively reducing the structural quality and expanding the flight envelope, thereby saving energy consumption. Therefore, the flying wing layout aircraft is superior to the traditional layout aircraft in terms of speed, range and stealth performance. [0003] However, while this special aerodynamic layout brings a large lift-to-drag ratio, it also brings difficulties to the design of the flight control system. First of all, due to the large aspect ratio of the wing and the short wing body, c...

Problems solved by technology

Although this one-piece wing layout can effectively reduce flight resistance, improve the force on the root of the wing and reduce the structural weight to a certain extent, it strictly limits the layout of the engine, and at the same time does not give full play to the role of the wing in improving control. and improve aerodynamic performance
