Method and apparatus for supplying a gas jet over an aerodynamic structure

摘要

An apparatus for supplying a gas flow over an aerodynamic structure is provided. The apparatus includes a fluid source for supplying the gas flow and a flow control actuator configured to receive the gas flow from the fluid source. The flow control actuator is also configured to selectively direct the gas flow over the aerodynamic structure when the flow control actuator is in at least one predetermined operating position and to restrict the gas flow over the aerodynamic structure when the flow control actuator is in another of the predetermined operating positions.

1. An apparatus for supplying a gas flow over an aerodynamic structure, the apparatus comprising:
a flow control actuator coupleable to a fluid source to receive a gas flow from the fluid source, said flow control actuator configured to selectively direct the gas flow over the aerodynamic structure when said flow control actuator is in at least one predetermined operating position and to restrict the gas flow over said aerodynamic structure when said flow control actuator is in another of the predetermined operating positions, said flow control actuator comprising: an outer member including a first slot; an intermediate member positioned at least partially within said outer member, said intermediate member including a second slot; and an inner member positioned at least partially within said intermediate member, said inner member including a helical slot that substantially circumscribes said inner member.
