Abstract
An airfoil structure comprising a main body and at least one control surface attached to the main body by a flexible attachment, the flexible attachment comprising a flexible first surface and a flexible second surface opposed to the flexible first surface, each of the flexible first surface and the flexible second surface having a waveform structure.
Claims15
An airfoil structure comprising:
- a main body;
- and
- at least one control surface attached to the main body by a flexible attachment, the flexible attachment comprising a flexible first surface and a flexible second surface opposed to the flexible first surface, each of the flexible first surface and the flexible second surface having a waveform structure.
A method of actuating a control surface of an airfoil structure, wherein the control surface is attached to a main body of the airfoil structure by a flexible attachment having a waveform structure, the method comprising:
- at least one of translating the control surface in a chord-wise direction relative to a main body of the airfoil structure;
- and
- rotating the control surface relative to the main body of the airfoil structure, wherein the translating and/or rotating of the control surface relative to the main body does not form a gap or discontinuity in the airfoil structure.
