Abstract

A turboshaft gearbox output gear arrangement (100) of a gas turbine engine, having: a power turbine shaft (110); a torque shaft (120), driven by the power turbine shaft (110), extending from a forward end (120F) to an aft end (120A); a gear shaft (122), driven by the torque shaft (120); a mating gear (125), driven by the gear shaft (122), wherein the mating gear (125) and gear shaft (122) define a gear mesh plane (127); a reference tube (130), coupled to the torque shaft (120), extending from a forward end (130F) to an aft end (130A), wherein the forward and aft ends of the reference tube (130) and torque shaft (120) extend along each side of the gear mesh plane (127); and a sensor (140D) that engages the reference tube (130) and the torque shaft (120) to measure twist in the torque shaft (120), wherein angular movement of the reference tube (130) relative to the torque shaft (120) is indicative of torque reacted in the torque shaft (120).
