摘要：An apparatus for the detection of the icing-up of an aircraft rotor. Theapparatus has a sensor (10) for the tractive force and a sensor (11) for torque; for
measuring respectively the axial force and the torque exerted on the shaft of the rotor. Adevice (12) calculates the ratio between these two quantities. A determination is alsomade, as a function of the flying conditions, of what should be the nominal value of thisratio in the absence of icing-up. Finally a device (12) compares the calculated ratio withthe nominal ratio.
