| 英文摘要: |
| In view of the measurement requirements of aero-engine inlet dynamic temperature field，a method of dynamic temperature
field measurement based on fine wire thermocouple was proposed. For the first time，a kind of measure rake of engine inlet flow field was
designed by floating connection structure，and the strength of the measure rake was calculated.A kind of small inertia thermocouple was
designed by using the fine wire lap method. The results of static calibration of the thermocouple show that the small inertia thermocouple
satisfies the requirement of Level I accuracy. The application of the thermocouple in an aircraft engine measurement shows that the design
meets the rake requirements of engine measurement. |
