Abstract
Disclosed are a method and a device to measure wind-related stresses in a rotating system. It is based on the studies made by the Applicant which have shown that the power given by the motors driving the system rotationally are a function of these stresses. A measurement of the power, or of any quantity characteristic of this power (such as current, cos.phi. pressure, etc.) therefore enables a simple measurement of the wind-related stresses. If we set a limit value of power (or of a characteristic quantity) related to the limit velocity of the wind beyond which the forces to which the system is subjected are excessive, it becomes easy, by way of a comparison, to obtain a condition for the operation of the motors. The disclosure can also be used, in systems carrying out an angle measurement, to make a correction of this measurement.
