Abstract
An embodiment of the present disclosure provides an airfoil comprising a trailing edge, a first fluidic outlet, and a first fluid supply. The trailing edge can have a first surface and a second surface opposing the first surface. The first fluidic outlet can be positioned on one of the first or second surfaces. The first fluid supply can be configured to eject a fluid out of the first fluidic outlet to alter an aerodynamic load experienced by the airfoil.
Claims20
An airfoil comprising:
- a trailing edge having a first surface and a second surface opposing the first surface;
- a first fluidic outlet and a second fluidic outlet each positioned on the same surface of the one of the first or second surfaces;
- a first fluid supply configured to eject a fluid out of the first and second fluidic outlets to alter an aerodynamic load experienced by the airfoil;
- and
- a first fluidic bypass switch in fluid communication with the first and second fluidic outlets, the first fluidic bypass switch configured to provide three fluid output configurations:
- a first fluid output configuration in which fluid from the first fluid supply is ejected from the first fluidic outlet;
- a second fluid output configuration in which fluid from the first fluid supply is ejected from the second fluidic outlet;
- and
- a third fluid output configuration in which fluid from the first fluid supply is ejected from neither the first fluidic outlet nor the second fluidic outlet.

An airfoil comprising:
- a trailing edge having a first surface and a second surface opposing the first surface;
- a first fluidic outlet and a second fluidic outlet each positioned on the first surface of the trailing edge;
- and
- a first fluid supply configured to eject a fluid out of the first and second fluidic outlets to alter an aerodynamic load experienced by the airfoil;
- wherein the first fluidic outlet is configured such that fluid ejected from the first fluidic outlet is ejected in a direction tangential to the first surface of the trailing edge;
- and
- wherein the second fluidic outlet is configured such that fluid ejected from the second fluidic outlet is ejected in a direction normal to the first surface of the trailing edge.
4 more elements
An airfoil comprising:
- a trailing edge having a first upper, suction surface and a second lower, pressure surface opposing the first surface, wherein the airfoil is configured to generate lift;
- at least one fluidic outlet positioned on the first surface;
- and
- at least one fluidic outlet positioned on the second surface;
- wherein a controlled ejecting of a fluid from one or more of the at least one fluidic outlet positioned on the first surface and from one or more of the at least one fluidic outlet positioned on the second surface bi-directionally alters aerodynamic loads experienced by the airfoil;
- wherein a first of the at least one fluidic outlet positioned on the first surface is oriented such that fluid ejected from the first fluidic outlet exits the first fluidic outlet in a direction tangential to the first surface;
- and
- wherein a second of the at least one fluidic outlet positioned on the first surface is oriented such that fluid ejected from the second fluidic outlet exits the second fluidic outlet in a direction normal to the first surface.
