A new type of variable aerodynamic layout aircraft

Abstract

The invention relates to a novel variable aerodynamic layout aircraft, belonging to the field of aerospace technology, comprising a flying wing fuselage (5), canard wings (2), canard wing actuators (3), canard wing storage slots (1), Canard retractable mechanism stem (4) and sleeve (10), aileron (6), flap (7), storage slot opening fairing lower piece (8) and upper piece (9); the fuselage The main body is a single flying wing, and the front edge of the flying wing has a canard storage slot (1) parallel to the chord direction. The canard storage slot can accommodate the canard (2), and the canard (2) passes through the canard actuator (3 ) is connected with the stem (4) of the canard retractable mechanism and the sleeve (10), the canard retractable mechanism is connected with the fuselage at the bottom of the storage slot, and there is a fairing lower piece (8) that can be opened and closed at the storage notch and top sheet (9). The invention combines the advantages of flying wing layout and canard layout on the same type of aircraft, and simultaneously has the advantages of radar invisibility, high subsonic lift-to-drag ratio, short take-off and landing, and excellent low-speed maneuverability.

Description

technical field [0001] The invention relates to a novel variable aerodynamic layout aircraft, which belongs to the technical field of aerospace. Background technique [0002] Flying wing layout aircraft has strong radar invisibility, and due to the high aspect ratio of flying wings, large interior space, and large fuel capacity, it has high subsonic lift-to-drag ratio and range load performance. However, due to the lack of a control surface with a longer control arm on the pitch channel, the maneuverability of the aircraft with the flying wing layout is poor on the pitch channel, and the flight capability at large angles of attack is seriously insufficient, the agility is poor, and the take-off and landing speed requirements are high. [0003] The canard layout aircraft is just the opposite. The existence of canard wings is not conducive to stealth (the J-20 fighter with the canard layout has to make some special designs for stealth). There is no advantage over the flying w...

Problems solved by technology

[0006] The design of changing the aerodynamic shape through mechanical deformation can be found in patents such as CN201110320155.X, CN201510197632.6, CN201611123391.1, but these patented technologies are respectively the deformation of the geometric shape of the wing, the deformation of the installation position of the rotor in the helicopter, and the unmanned quadrotor. The mechanical deformation of the aircraft, the geometrically variable aerodynamic shape design that has been realized or proposed at present is an attempt to solve other performance contradictions in the aircraft aerodynamic shape scheme, and there is no possible solution to the contradiction between the flying wing layout and the canard layout.
