MECHANISM FOR UNFOLDING AND LOCKING AN AERODYNAMIC RUDDER HAVING TWO FOLD AXES

摘要

The invention relates to the field of aircraft, and more particularly to foldable airfoils and to mechanisms for unfolding and locking same. A mechanism for unfolding and locking an aerodynamic rudder having two fold axes comprises a pylon and a pivotable root panel which are connected by half-shafts, said root panel being lockable, and a source of high-pressure gas disposed inside the pylon for use as an actuator. During the unfolding of a tip panel, a connector mounted on a rod performs an additional translational movement once the root panel has assumed an unfolded working position, said connector acting on a pusher which, in the course of a linear movement, transmits unfolding moment to a shaft disposed in the root panel and connecting the unfolding mechanism via a tensioning member to the tip panel, allowing the latter to unfold. The technical result is the possibility of accommodating an aircraft inside the confined space of a launch canister.
