| description | According to the high-precision rapid aerodynamic heat identification method, temperature data needing to be identified is divided into N identification time periods, segmentation identification is carried out according to the time sequence to reduce the solving data size and accelerate iteration, data transmission is fully utilized in solving, calculation time is reduced in a geometric progression mode, and the identification accuracy of the aerodynamic heat is improved. The solution time is close to the time of the total amount/N, and meanwhile, the direction of heat flow variation is determined by comparing the identification temperature with the reference temperature; errors caused by comparison of identification heat flows fixed in all previous'identification time periods' and real heat flows are superposed on a measured temperature according to a certain proportionality coefficient, the measured temperature is corrected, a reference temperature of a current time point is formed, and reference distortion |
