Claim:
1. An aerodynamic control device, comprising: a body defining a control surface; a plurality of pneumatic motors coupled to the body, each pneumatic motor comprising a sealed chamber and at least one port configured to provide access into/out of the sealed chamber, wherein the pneumatic motors are positioned with respect to the control surface such that pressurizing one or more of the plurality of sealed chambers via the respective ports results in a change in configuration of at least a portion of the control surface; a source of pressurized gas connected in fluid communication with the port of each pneumatic motor; a controller, at least one valve configured to selectively permit pressurized gas to be delivered to the port of each pneumatic motor, and at least one sensor, wherein the controller is configured to control the at least one valve based on the output of the at least one sensor; wherein the controller and the at least one valve are configured to sequentially supply pressurized air to the chambers of the plurality of pneumatic motors.
