A mechanism (10) is disclosed for deploying air foils (12, 14) about mutually perpendicular axes (20, 22) in synchronized motion. The mechanism includes a bridge structure (18) which mounts the air foils (12, 14) and uses a hydraulic circuit to link and/or to drive two rack shafts (30) which rotate rotation gears (36) to transition the air foils about one axis while sliding gear racks (92) moving about a boss (94) causes the air foils to translate about the second axis. The air foils can be locked in the deployed position by locking the rotation gears with rotation locks (50). A hydraulic damper (68) damps the movement of the air foils to the deploy'ed position to control the speed of air foil deployment. An orifice rate adjustment screw in the damper allows the speed of deployment to be varied.;In a second mechanism (100), air flow initiates deployment of the wings by causing pivoting motion of a T-joint fitting (112). Meshed gear teeth between the wing (122) and the elevation plate (108) also causes the elevation plate to pivot. The axis of pivotal motion of the elevation plate (108) and the T-joint fitting (112) are offset so that the gear teeth on the elevation plate (108) causes the wing to move from the folded position to the elevated position. A pair of wings are deployed simultaneously by use of a cross shaft (134) that interconnects the elevation plates (108) of each wing deployment apparatus. A hydraulic damper (146) can be operated by the cross shaft (134) to allow control of the rate of deployment of the wings.
