Abstract
An assembly for controlling a vehicle, including a fluid contact surface constructed and arranged to act against a fluid passing over the fluid contact surface; and a support structure coupled to the fluid contact surface. The support structure is constructed and arranged to expand or contract between a first position and a second position, such that a first dimension of the support structure changes during movement of the support structure between the first position and the second position, while a second dimension of the support structure remains substantially constant during the movement of the support structure between the first position and the second position.
