Description

Aerodynamic wing aircraft

Technical Field

The aerodynamic wing aircraft belongs to the technical field of aviation.

Background

The traditional aircraft wing utilizes the air flow generated by the convex upper board surface and the convex lower board surface of the wing to generate lift force. The wing area span is increased along with the takeoff weight, so that the wing structure needs to be enhanced, the airplane weight is increased, the ground maneuverability is reduced, and the technical and economic performance of the airplane is influenced.

Disclosure of Invention

The technical problem to be solved by the aerodynamic wing aircraft is as follows: a new wing structure is designed to generate lift.

The technical scheme is as follows: the wing is arranged along the whole length of the fuselage, and the front edge of the wing surface is provided with a flat jet nozzle.

The aerodynamic wing aircraft (attached figure) consists of three parts, namely a fuselage, an aerodynamic wing and a jet engine 1. The aerodynamic wing consists of a longitudinal wing 3, a wing edge 4, a vertical tail wing 5, a steering rudder 6, an elevator 7, an aileron 13 and a flap 14. The longitudinal wings 3 are fixed to the top surface of the fuselage and arranged along the entire length of the fuselage. The upper side of the wing leading edge is provided with a jet engine 1 and a flat nozzle 2, and high-speed fuel gas sprayed by the jet engine 1 flows along the upper surface of the longitudinal wing 3. Two sides of the longitudinal wing 3 are provided with wing edges 4 vertical to the wing surface, so that the left and right diffusion of the gas flow in the fuselage section can be reduced. Two vertical tail wings 5 are arranged at the tail parts of the longitudinal wings 3, so that the stable flying of the airplane in the left and right directions is ensured. The rear part of the vertical tail wing 5 is hinged with a steering rudder 6 for controlling the left and right steering of the airplane. The rear edge of the longitudinal wing 3 is provided with an elevator 7 for controlling the airplane to ascend and descend. The left and the right of the front edge of the longitudinal wing 3 are respectively hinged with a flap 14, so that the lift force is increased during take-off; when falling, it acts as a speed reducer. Two ends of the front edge of the longitudinal wing 3 are respectively hinged with an overhanging aileron 13, so that the airplane can be inclined transversely to assist in turning when the airplane turns.

The jet engine 1 is composed of an engine body and a flat nozzle 2. The engine body is arranged at the front edge of the longitudinal wing 3 and can be uniformly distributed in one or a group. The nozzles of a group of engines are all collected in a flat nozzle 2.

The tail part of the fuselage is provided with two horizontal tail wings 8 which play a role of horizontal stability. The lower surface of the horizontal tail wing 8 is hinged with a speed reducing plate 9 for reducing speed when falling. The other structures inside and outside the airplane body comprise a cockpit, an instrument control system, a passenger and cargo hold, a front wheel, an undercarriage, a landing wheel and the like of the existing airplane.

The jet speed V of the jet engine 1 during flight_{Spraying nozzle}And moving the airplane to fly. Aircraft meets air resistanceTo make the flying speed V of the airplane_{Fly away}＜V_{Spraying nozzle}. Air velocity V of the air under the longitudinal wing 3 with respect to the aircraft rear flow_{Qi (Qi)}Is equal to the flying speed V_{Fly away}Therefore, is at_{Qi (Qi)}＜V_{Spraying nozzle}The longitudinal wings 3 generate lift force and float in the air.

The aerodynamic wing aircraft has the beneficial effects that: the air injection generates both thrust and lift; the windward side of the wing is less, the flight resistance is small, the oil consumption is reduced, and the reflection of the received radar waves is less, so that the wing is beneficial to hiding; the wingspan is small, and the ground take-off and landing maneuverability is good.
