Patent ID: 8683807

Claim:
A jet engine exhaust nozzle flow effector comprising: an elastically deformable chevron having a root and a tip, said chevron formed to have a radius of curvature adapted to match a portion of the geometry of a jet engine exhaust nozzle exit such that an inner surface and an outer surface are defined and oppose one another with said inner surface facing a center of the nozzle exit, wherein the inner surface and the outer surface are formed from a first material; and at least one shape memory alloy (SMA) actuator embedded within said chevron between the inner surface and said outer surface to be closer to said outer surface than said inner surface and substantially spanning from at least a portion of said root to said tip, wherein said SMA actuator is positioned above a neutral axis of said chevron, wherein the SMA actuator comprises an SMA that is accessible at said root, and wherein when the SMA is actuated the tip moves away from the center of the nozzle exit.
