Abstract
An improved actuator system is provided for safe displacement of a folding wing section of an aircraft between a folded storage position and a deployed position for normal flight operations. The actuator system comprises an electrohydraulic actuator forming part of a mechanical linkage between an outboard folding wing section and an adjacent inboard wing section. The electrohydraulic actuator is adapted to be reversibly driven either electrically or hydraulically to displace the outboard wing section, and includes an improved brake unit for automatically retaining the outboard wing section in place upon interruption of drive power input to the actuator. The actuator system further includes an improved latch pin unit adapted for electric or hydraulic powered operation to positively lock the outboard wing section in the deployed position.
