摘要:
An aerial vehicle controlled and propelled by oscillatory momentum generators and method of flying a vehicle. A vehicle capable of flight is disclosed. The vehicle includes at least one wing including at least one oscillatory momentum generator mounted therein. A thrust force from the oscillatory momentum generator is directed outwards over the wing causing a causing a lift-generating air flow over a surface of the at least one wing. Further disclosed is a method of flying a vehicle including providing at least one wing having at least one oscillatory momentum generator mounted therein and applying a thrust force generator which is directed outwards over the wing so that a lift generating air flow is created.

This invention discloses a fluid dynamic system including a fluid medium separated from a solid medium by a solid boundary, one of which media is moving with respect to the other, apparatus for controlling the motion of the moving medium, comprising, a perturbation-producing element at solid boundary, and a drive for cyclically driving the perturbation-producing element to produce cyclical fluid perturbations in the fluid medium sufficient to alter the motion of the moving medium. A method for including a fluid medium separated from a solid medium by a solid boundary in a fluid dynamic system is also disclosed. 00000

摘要:
A vertical axis wind turbine comprises upper and lower rotor blades and upper and lower bearing assemblies. Horizontal members connect the upper rotor blades to the upper bearing assembly and the lower blades connect the upper rotor blades to the lower bearing assembly. The upper rotor blades can be arranged vertically or non- vertically. In non- vertical arrangements, the upper rotor blades can be twisted or swept back in a straight manner. The turbine can be self-supporting with a need for a continuous vertical axis connecting the bearing assemblies. Sweeping jet actuators are incorporated into the rotor blades to deliver oscillating air jets to surfaces of the rotor blades to delay occurrence of dynamic stall. Conduits in the blades can deliver pressurized flow of air to the actuators. The turbine can be supported by a structure that can exerts only horizontal and/or lifting forces on the rotor blade assembly to reduce the load on the lower bearing.
