Abstract
This invention is an apparatus of vortex generator and spoiler that functions as vortex generators and spoilers by ejecting air streams or fluid streams in a predetermined position and in a predetermined arrangement and this apparatus can be controlled by pressure differentials between at least two predetermined areas or through the movement, including fully or partial deployment, retraction, and rotation, of an affiliated dynamic surface, such as the leading-edge slat or the trailing-edge flap, for the purpose of achieving desired aerodynamic or fluid-dynamic performances, such as avoiding air flow separations over aircraft wings and automotive spoilers or preventing out-of-control operations of wind turbine blades.
Claims3
An apparatus to function passively as a vortex generator and a spoiler, comprising:
- a lift body generating dynamic force when in relative motion against a non-solid medium, including air, gas, water, fluid, or a combination thereof,
- said lift body comprising a plurality of nozzles for ejecting at least one stream,
- said lift body comprising a plurality of dynamic surfaces being coupled onto said lift body and being deployable, and
- said plurality of nozzles being arranged spanwise along the dynamic surfaces and operative from the movement of said plurality of dynamic surfaces;
- wherein
- said plurality of nozzles are disposed in predetermined positions to allow movement of said plurality of dynamic surfaces to control, manipulate, or influence the characteristics of said at least one stream according to a pressure differential between at least two predetermined areas.
