Abstract

The invention relates to the technical field of flow control, in particular to an active-passive combined flow control device and method. The active-passive combined flow control device includes a passive flow control generator, an active flow control actuator and a drive unit, and the drive receives control commands sent by external control equipment, the passive flow control generator and the active flow control actuator are driven to work according to the control commands, wherein the control commands are generated by the external control equipment according to present flow field parametersand configuration parameters of the passive flow control generator and the active flow control actuator. According to the active-passive combined flow control device, the effect of flow control of wide envelopes and variable working conditions can be achieved.

Description

technical field [0001] The present application relates to the technical field of flow control, in particular to an active and passive combined flow control device and method. Background technique [0002] Flow will cause a series of problems in engineering practice, for example: the excessive resistance of the aircraft will lead to excessive energy consumption and increase in fuel costs, and the aircraft will stall and have small lift-to-drag ratio under different flight conditions; It will encounter problems such as severe lift fluctuations and insufficient crosswind stability; high-rise buildings also face problems such as large wind loads and wind-induced vibrations. [0003] Flow control technology is an important means to solve the above problems. The use of efficient flow control technology can achieve the goals of reducing drag, increasing lift, reducing pulsating lift, improving stability, reducing wind-induced vibration, etc., and finally solving a series of enginee...
