Abstract

The present invention provides systems and methods for self-rotating fluid traversal actuators. The turbine rotates in response to the fluid flow, and the outer cylinder has longitudinal slots ejecting the fluid flow. An inner cylinder rotates within the outer cylinder in response to rotation of the turbine, and at least one helical slot of the inner cylinder ejects fluid flow into the longitudinal slot.

Description

Technical field [0001] Embodiments of the present disclosure generally relate to hydrodynamic design. More specifically, embodiments of the present disclosure relate to the design of fluid actuators. Background technique [0002] Flow control can be used to use fluid sources, such as bleed air from an engine or dedicated compressor, to enhance lift performance. The air flow from the fluid source is ejected from the aircraft across the top of the wing or flap in the general direction of the air flow. The jet of air flow imparts momentum to the air flow on the wings or flaps. This momentum causes the airflow to better follow the surface of the wing or flap. Therefore, the circulation flow around the entire wing including the wing or flap is increased, and higher lift is obtained. [0003] However, current airflow control methods require a considerable amount of jet airflow to achieve meaningful design goals. Aircraft engines can be used to supply air to be actuated by "exhaust" ...
