Patent ID: 8733080

Claim:
A thrust reverser and VAFN arrangement comprising a movable thrust reverser cowl moveable between stowed and deployed positions by a thrust reverser actuator, a VAFN cowl mounted for movement relative to the thrust reverser cowl, and a VAFN actuator arrangement comprising a VAFN actuator and a VAFN gearbox independent of the thrust reverser actuator wherein the VAFN actuator and the VAFN gearbox are mounted upon the thrust reverser cowl, the VAFN actuator having a rotatable drive input and an output, the output being connected to the VAFN cowl such that operation of the VAFN actuator drives the VAFN cowl for movement relative to the thrust reverser cowl, a motor and a drive transmission arrangement for transmitting rotary drive from the motor to the rotatable drive input of the VAFN actuator, the transmission arrangement including a telescopic drive coupling, and wherein an output shaft of the telescopic drive coupling coupled with the VAFN gearbox telescopes to accommodate movement of the thrust reverser cowl between its stowed and deployed positions.
