Variable camber trim units, aircraft comprising the same, and associated methods of operation

Abstract:

A variable camber trim unit comprises a housing, an input gear, and an output gear. The input gear and the output gear are rotatably supported by the housing. The variable camber trim unit is selectively configurable to one of a coupled configuration or a decoupled configuration. When the variable camber trim unit is in the coupled configuration, rotation of the input gear relative to the housing causes rotation of the output gear relative to the housing. When the variable camber trim unit is in the decoupled configuration, rotation of the input gear relative to the housing does not cause rotation of the output gear relative to the housing, and the output gear is capable of at least 5.degree. and no more than 15.degree. of rotation relative to the housing.
