Abstract

A hub moment sensor is disclosed for an aircraft having a horizontal rotor, a rotor fixed mast for supporting the rotor above the aircraft body, and a support ring formed on the aircraft body for attachment to the rotor fixed mast. The sensor comprises an annular flange formed on the end of the rotor fixed mast remote from the rotor, and coupling means for securing the flange to the support ring, the coupling means including stress measuring means, whereby the moments acting on the aircraft may be sensed.
