Abstract
A system verifies torquing of pressure fittings in an aircraft wheel well. A strain gauge and an ultra-wide band (UWB) pulse signal generator are placed on a wrench used to torque the fittings. The strain senses the torque applied by the wrench, and the pulse signal generator generates UWB pulse signals indicating the location of the fitting and the torque applied to the fitting. The pulse signals are received by UWB radios within the wheel well, which generate location measurements based on the received pulse signals. A processor automatically calculates the location of the fitting being torqued based on the location measurements, and a display produces a 3-dimensional image of the fittings and their torque status.
