The invention provides a wing with a turbulent flow auxiliary device and a flight device comprising the same, the wing with the turbulent flow auxiliary device comprises a flap and a turbulent flow device, the turbulent flow device is installed on the wing surface of the flap and located at the position where airflow of the flap is separated, and the turbulent flow device is installed on the wing surface of the flap and located at the position where airflow of the flap is separated. And the turbulent flow device can be opened or closed along the wing surface of the flap. The turbulent flow auxiliary device is arranged on the flap, so that the flow separation condition of the wing surface of the aircraft flap can be effectively improved, airflow separation is slowed down, and then the lift augmentation effect is achieved. Meanwhile, the wing with the turbulent flow auxiliary device is simple in structure and easy to install, a good technical effect can be achieved through low manufacturing cost, and the overall performance of the wing is obviously improved.
Description
technical field [0001] The invention relates to the field of aircraft flap design, in particular to a wing with a turbulence auxiliary device and a flying device comprising the same. Background technique [0002] In the prior art, in order to obtain a larger maximum lift coefficient to control the approach speed of the aircraft, the flap deflection of the modern large passenger aircraft is often designed to be larger. In this case, it is usually accompanied by the auxiliary deflection of the spoiler to control reasonable seam parameters. [0003] Therefore, there is a certain degree of separation flow on the flap surface, especially when the aircraft is at a large angle of attack or near the stall zone, there will be a large area of separation flow on the flap surface. [0004] This separation flow will cause the aerodynamic characteristics of the aircraft to show phenomena such as lift drop, pitch and roll. At the same time, it will cause problems such as structural vib...
