The e N method based on linear stability analysis is currently one of the most widely used methods for transition prediction; however, the selection of the transition criterion NT value shows significant scatter at high Mach numbers. The linear stability analysis and e N method are used to conduct stability analysis and N-factor envelope calculations for the lifting calibration model at Mach numbers of 5 and 8, and for Reentry F at a Mach number of 20. Combining the transition onset locations obtained from wind tunnel results and flight data, the calibration of the transition criterion NT value at high Mach numbers is carried out. The results show that for the lifting calibration model, the transition criterion NT is approximately 5.3 to 6.5 under different angles of attack at Mach number of 5, and approximately 4.8 to 5.3 at Mach number of 8. For Reentry F, the transition onset locations vary significantly at different altitudes, but the transition criterion NT does not change significantly, being approximately 9.55 to 9.73.
