Abstract
An airfoil of an aerodynamic surface including: a control surface having an upper surface and a lower surface, and an actuator configured to elevate or lower the control surface, wherein at least a portion of one of the upper surface and the lower surface of the control surface is auxetic with a negative Poisson ratio, and the other of the upper surface and the lower surface of the control surface includes a material with a higher Poisson ratio.
Claims17
An airfoil of an aerodynamic surface, the airfoil comprising:
- a control surface comprising an upper surface and a lower surface, and
- a primary actuator assembly configured to elevate or lower the control surface;
- wherein at least a first portion of one of the upper surface and the lower surface of the control surface is auxetic with a negative Poisson ratio, and at least a second portion of the other of the upper surface and the lower surface of the control surface comprises a material with a Poisson ratio higher than the Poisson ratio of the first portion.
