Abstract

Example torque tube assemblies may be used with aircraft high lift devices. An example torque tube assembly includes a torque tube having a first end and a second end opposite the first end. A first fitting is coupled to the first end and a second fitting is coupled to the second end. The first fitting is to be coupled to a first high lift device of an aircraft. The second fitting has a spline section. The torque tube assembly also includes a sliding spline shaft having a channel and a first yoke. The second fitting is slidably received within the channel. The torque tube assembly further includes a spline coupling having a second yoke, which is coupled to the first yoke of the sliding spline shaft to form a U-joint. The spline coupling is to be coupled to a second high lift device of the aircraft.
