초록 ▼

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.

대표청구항 ▼

A wing fold actuator system for use in an aircraft having an outboard wing section connected to an inboard wing section for movement between a deployed position and a folded position said actuator system comprising: an electrohydraulic actuator connected between the inboard and outboard wing sections, said electrohydraulic actuator including a driven member for displacing the outboard wing section between the deployed and folded positions; said electrohydraulic actuator includes a power cylinder having a base end connected to one of the inboard and outboard wing sections, and a ram adapted for extension and retraction movement with respect to said power cylinder and having a free end connected to the other at the inboard and outboard wing sections; said electrohydraulic actuator further including hydraulic drive means and electric motor drive means alternatively operable for reversible power drive displacement of said driven member, said electric motor drive means including a rotatable output shaft connected to said driven member, said output shaft being rotatably back-driven by said driven member upon operation of said hydraulic drive means to displace said driven member; and said hydraulic drive means includes a power piston connected to said ram and mounted within power cylinder, said power piston cooperating with said power cylinder to define a pair of fluid chambers at opposite sides of said power piston, and means for controllably supplying hydraulic fluid under pressure to one of said chambers while exhausting the other of said chambers to displace said power piston within said power cylinder; said actuator further includes a central drive shaft, and reversible transmission means for rotating said drive shaft in response to displacement of said power piston within said power cylinder, said output shaft of said electric motor drive means being connected to said drive shaft for rotation therewith; and a brake unit for preventing displacement of said driven member upon interruption of power drive displacement thereof, said brake unit including a brake member carried on said output shaft for rotation therewith, a friction member, means for engaging said brake and friction members to prevent rotation of said output shaft in the absence of operation of one of said drive means, and means for disengaging said brake and friction members to permit rotation of said output shaft during operation of one of said drive means for power drive displacement of said drive member.
