ABSTRACT:
An apparatus for and method of depolying a movable aerosurface of an aerial vehicle from a folded position to an unfolded, operative flight position. The aerosurface, such as a fin for example, includes a pivotal base member and a control surface connected to the base member for movement relative thereto. An actuator effects pivotal movement of the aerosurface at a predetermined angular rate of deployment. During the initial depolyment cycle the control surface is deflected relative to the base member in a direction and manner imparting aerodynamic forces against the aerosurface to accelerate the angular rate of deployment of the aerosurface. Thereafter, the control surface is deflected in a reverse direction during a later portion of the deployment cycle to impart aerodynamic forces for decelerating and dampening the angular rate of aerosurface deployment to reduce arresting loads as the aerosurface approaches its fully unfolded position.
