For high accuracy measurement of aero-engine exhaust temperature,a conjugate heat transfer(CHT)numerical simulation method was employed to estimate different sources of steady state errors and their variation characteristics of a typical shielded thermocouple working at different Mach number condition namely 0.2,0.3,0.4,0.5,0.6.Theresults showed that under the Mach number less than 0.3 working condition,the radiation error took the highest proportion of total error,while at the 0.6 Mach number,the conductio...
