Abstract: A rotorcraft propulsion system includes a mast coupled to a rotor assembly, a gear coupled to the mast, the gear during use producing an axial reaction force, a flexure shaft extending from the gear, where the flexure shaft does not rotate with the gear and the flexure shaft flexes in response to radial loads from the gear, and a load cell on the flexure shaft to measure the axial reaction force.
