abstract

In the measurement of aerodynamic parameters behind rotors, measurement errors may be caused by rotation of rotors. These errors are define as rotation state errors which contain two types of errors: weighted error and response error. In this paper, the equations of rotation state errors are derived by the sweep in tegral of the square wave for the first order system. It provides a clear concept for the measurement errors behind rotors and presents the method and equations for analysing and estimating the rotation state errors.
