Abstract

A turboshaft engine transmission (201) with a torque measurement system (202) is provided. The turboshaft engine transmission (201) includes a front housing (210), a rear housing (220), a mating flange (230) axially interposed between the front and rear housings (210, 220), the mating flange (230) defining a sensing bolt hole (240), assembly bolts (260) disposed to assemble the front and rear housings (210, 220) to the mating flange (230) with a preload sufficient to maintain assembly during engine operational conditions and a sensing bolt (250) installed in the sensing bolt hole (240) to measure forces exerted on the mating flange (230) by the front and rear housings (210, 220).
