Canard aerodynamic configuration of subsonic-velocity high-maneuver drone aircraft

Abstract

The invention discloses a canard aerodynamic configuration of a subsonic-velocity high-maneuver drone aircraft. A pair of canards is symmetrically arranged on the two sides of an aircraft body, the pair of canards utilizes symmetrical wing type with the maximum thickness of 10% to 14%, the sweepback angle of each leading edge is 30 to 32 DEG C, and the area of the canards is 8% to 12% of the area of a wing; a pair of wings is symmetrically arranged on the two sides of the back part of the aircraft body, ailerons are arranged on the outer sides of the wings and can be taken as flaps for lift enhancement according to the flight state, the wings utilize spanwise variable camber reverse-bending wing type with the maximum thickness of 8% to 12%, the sweepback angle of each leading edge of the wings is 38 to 42 DEG C, the wings are provided with twin vertical fins, the twin vertical fins utilize symmetric wing type with the maximum thickness of 6% to 10%, the area of the twin vertical fins is 15% to 25% of the area of the wings, and rudders are arranged on the twin vertical fins. According to the duck-type aerodynamic layout, the preposition double-canard configuration can remarkably increase the stalling angle of attack of an aircraft so as to provide conditions for high maneuver; a wing body fusion layout can also remarkably reduce the resistance of the aircraft and increase the speed; an air inlet of an inlet is formed in the ventral, and the structure is in an embedded type semi-crescent shape, so that the collision damage of the air inlet in a drone aircraft recycling process can be avoided.

Description

technical field [0001] The invention belongs to the technical field of aircraft aerodynamic layout design, and relates to an aircraft aerodynamic layout, in particular to a canard aerodynamic layout of a subsonic large maneuvering target drone. Background technique [0002] The target drone is an effective aerial target used to test the performance of air combat weapon systems such as fighter jets, missiles, and artillery, and is vividly called "the whetstone in the air". In order to more realistically simulate enemy aircraft during military exercises or weapon tests, the target aircraft must not only have the ability of remote control flight or pre-planned routes of ordinary drones, but also have the ability to simulate objects in terms of speed, maneuverability and stealth. Partial or full performance. Therefore, in the design stage of the target drone, the importance of its aerodynamic layout design is no different from that of fighter jets or missiles. [0003] In the ...

Problems solved by technology

[0003] In the history of aviation development in the world, at the beginning, the retired fighters were remanufactured and used as target drones. However, the source and quantity of such target drones are not fixed and cannot meet the needs of military training. Therefore, all military powers in the world are vigorously developing different types and performances. advanced target drone
