Abstract
A method of reducing aerodynamic drag on a moving blunt-edged body, the method comprising actively generating a flow of air at a blunt edge of a body and using the generated flow of air to control an external flow of air moving relative to an edge of a moving blunt-body.
Claims15
An apparatus adapted to reduce aerodynamic drag on a vehicle moving through a fluid, the apparatus comprising:
- (a) an apparatus housing including:
- a first outer surface adapted to extend outward with a downward inclination from an upper edge of the vehicle while the housing is mounted on a trailing surface of the vehicle;
- and
- a second outer surface adapted to extend outward at substantially right angles from the trailing surface of the vehicle from a location below the upper edge;
- and
- (b) a flow generator within the housing, the flow generator adapted to generate at least one flow which controls an external flow at an edge of the vehicle on which the apparatus housing is mounted.
