Problems solved by technology

However, the amount of blowing air required for continuous blowing in the span direction at the leading edge of the canard is still relatively large. We consider implementing pulse blowing in the span direction at the leading edge of the canard

Abstract

The invention which aims at close-coupled canard type configuration aircrafts provides an efficient indirect vortex control method and a device thereof. Places over a canard leading edge and at a certain height from the canard surface are respectively symmetrically provided with a jet tube, nozzle directions of the jet tubes parallel to the canard leading edge, high-speed pulse jets are jetted through the nozzles to generate a fluid vortex ring so as to increase the intensity of canard leading edge vortex and increase the angle of attack of canard configuration during canard leading edge vortex breakdown, and beneficial interference of the canard leading edge vortex and wing leading edge vortex is utilized to generate an indirect vortex control effect so as to enhance the intensity of the wing leading edge vortex and delay wing leading edge vortex breakdown when the angle of attach is large, so the configuration lift of the canard configuration aircraft is improved, the stall angle of attack is increased; and simultaneously the pulse frequency and the pulse width of pulse blowing are controlled through a solenoid valve, so the air entrainment amount is reduced to realize high efficiency and energy saving.

Description

technical field [0001] The invention relates to a canard vortex control method and device for a canard layout aircraft in the aerodynamic layout of the aircraft, more particularly, a method and device for controlling the canard vortex of a canard layout aircraft with close-range coupling. The present invention controls the canard leading edge vortex generated by the canard wing by using the pulse jet flow along the leading edge direction on the canard layout aircraft at close distance, and uses the canard leading edge vortex to indirectly control the main wing leading edge vortex generated by the main wing. To achieve the effect of improving the lift force of the canard layout aircraft and increasing the stall angle of attack of the canard layout aircraft, thereby achieving high-efficiency control. Background technique [0002] In the aerodynamic layout of the aircraft, the canard layout aircraft is relative to the conventional layout aircraft. It is generally considered tha...
