The BWB-UG is a glider with a smooth and integrated fuselage and wing.Its lift-to-drag properties are some of the most significant factors affecting its performance.In order to improve its hydrodynamic characteristics, the method of steady-stream active flow control (SS-AFC) is proposed.

The computational fluid dynamics method is used to numerically investigate the SS-AFC of the BWB-UG.The mechanism of the SS-AFC effect on the lift-to-drag characteristics is revealed from popularfilm.blog the flow field aspect.The flow field of the BWB-UG before and after click here installing the SS-AFC was simulated using FLUENT.

The results show that the SS-AFC can effectively optimise the hydrodynamic characteristics of the BWB-UG and can optimise the structure of the flow field around the BWB-UG.The steady-suction AFC can increase the lift-to-drag ratio of the BWB-UG by up to 45.01%.

With the steady-jet AFC, the lift-to-drag ratio of the BWB-UG can be increased by as much as 93.17%.
