The full thermodynamic engine start model based on component matching still needs to be improved in terms of accuracy and numerical convergence. A calibration method of starter assisted air start (SAAS) model based on backbone characteristics, spool losses and heat soakage parameters was proposed, including the target, design of freedom, solver and calibration procedure. Both calibration and validation cases were demonstrated. Results showed that the prediction of start time after calibration was within 2 s compared with the test results, and the error of maximum exhaust gas temperature was 5 K; critical parameter distribution, such as the high pressure spool acceleration rate, high pressure compressor exit static pressure, exhaust gas temperature etc., matched well with test data for the whole start process; the error of high pressure spool relative corrected speed was 1% and the error of high pressure compressor exit total pressure was about 3.5% under windmilling condition. The accuracy of the calibrated model was testified by the validation cases in the start envelope and improved significantly.
