摘要

The present invention relates to the field of aerodynamics. More particularly, the present invention relates to manipulating air flow over a surface, such as the surface of a duct of a ducted fan vehicle. By controlling air flow over, at, or around the surface of a duct, the flight of the vehicle can be controlled. One embodiment of the invention provides a vertical take-off and landing (VTOL) ducted-fan vehicle comprising means for producing steady or unsteady blowing at a surface of a duct for producing control forces and moments for controlling flight. The means for unsteady blowing can be provided by synthetic jets and the means for steady blowing can be provided by a pressurized air supply. The synthetic jets can be integrated into the ducted-fan vehicles in numerous ways, including at the surface of the leading and/or trailing edge of the ducts. The synthetic jets can be independently operated to control the flight of the vehicle. A novel use of these inventive flow control concepts is to apply the control asymmetrically to the duct in order to produce an imbalance in forces, thus resulting in a moment or torque, which can be used to control flight.
