Title: The Calculation of Windmilling Characteristics of a Gas Turbine Engine
Abstract: The gas turbine engine windmilling is a state that when the engine doesn't work,the rotors temporarily operate at a sub-steady rotating speed due to the airflow ram and the co-work of aerodynamics,rotor inertia and drag torque.During windmilling,computing aerodynamic parameters of gas turbine engine is difficult.In this paper,a method for computing windmilling drag is described.The method for computing windmilling characteristics of gas turbine engine is from reference[6].This method only requires design parameters of gas turbine engine to compute windmilling drag.According to this method,computer programs that compute windmilling drag of turbojet engine are edited.With this program,the windmilling characteristics of the turbojet engine are computed.The results indicate that the method from reference [6] is suitable for computing windmilling drag of gas turbine engines with no component characteristics.
