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, and the output gear is rotationally fixed relative to 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&#xb0; and no more than 15&#xb0; of rotation relative to the housing.

A clamping assembly for supporting a tubular object accessing a through-hole in a panel includes a clamp and a retainer configured to be positioned at least partially around the tubular object on a first side and a second side, respectively, of the through-hole. The clamp and retainer respectively include at least one clamp lock mechanism and at least one retainer lock mechanism configured to move between a respective open position and a respective closed position. The clamp includes at least one clamp hook configured to engage with the at least one retainer hole in the retainer in a snap-fit relation when the clamp and the retainer are in the respective closed position at the first side and second side, respectively, of the through-hole. A method of supporting a tubular object and an aircraft having the clamping assembly are also disclosed.

Apparatus and method for snap-fit clamping assembly

A torque tube assembly includes a torque tube and a spline coupling coupled to an end of the torque tube. The spline coupling has an opening to receive a spline gear on a drive shaft of an aircraft high lift device. The torque tube assembly also includes a retainer coupled to the spline coupling. The retainer blocks at least a portion of the opening in the spline coupling to prevent the spline coupling from being moved off of the spline gear on the drive shaft.
