High Speed and Accurate "E-T" Translation Method for Transient Aerodynamic Heating Control System

To simulate the transient aerodynamic heating condition of high speed flight vehicle, the high speed and accurate computer transient control system must be used to realize the high speed nonlinear dynamic controlling in the heating process of aerodynamic simulation experiment. To reach this aim, a very important problem of high speed and accurate E-T translation of sensor must be solved. A high speed and accurate E-T translation method of sensor for transient aerodynamic heating control system of high speed flight vehicle is proposed. This method possesses many advantages, such as, easy to calculation, with high translating speed and high accurate calibration. Using this method, the transient nonlinear dynamic controlling in the aerodynamic heating process of high speed flight vehicle and under high speed variable temperature field has been realized.
