An assembly and a method for manufacturing an assembly for transmitting torque to an aircraft actuator. The assembly and method include a torque tube having a longitudinal axis and an end fitting. The ending fitting includes a connector portion and an engagement portion that is inserted into the torque tube. The engagement portion includes a first end adjacent the connector portion, a second end opposite the first end, and a coupling region between the first and second end that includes an outer coupling surface having an outer diameter and a continuous groove formed thereon. The continuous groove includes two axial grooves that extend along the outer coupling surface along the longitudinal axis and a first parallel groove that extends circumferentially about the longitudinal axis along the outer coupling surface that joins the two axial grooves.

Axial load capable torque tube assembly and manufacturing methods thereof

A cone brake no-back includes an input no-back disk, an output no-back disk; and a no-back ball ramp mechanism operably connected to the input no-back disk and the output no back disk. An input no-back cone is operably connected to and supportive of the input no-back disk. The input no-back cone is axially loaded by an input no-back spring. An output no-back cone is operably connected to and supportive of the output no-back disk. The output no-back cone is axially loaded by an output no-back spring. A no-back input shaft is operably connected to the input no-back disk and the output no back disk, and a no-back output shaft is operably connected to the output no back disk.

Linear actuator with testable cone no-back and torque limiter

A sensor for detecting relative movement between two adjacent components includes a first member, a second member rotatable about an axis relative to the first member, and a fuse element including a first electrical contactor connected to the first member and a second electrical contactor connected to the second member. When the first member and the second member are skewed, the first electrical contactor and the second electrical contactor are not in electrical contact.
