Summary
The few examples of temperature measurement given here only touched upon the many varied applications of temperature measurement in turbine-engine development. Thermocouples, with careful techniques of application, and with an assist from optical methods in some of the hotter regions of the engine, are capable of meeting the needs of the designer for temperature data. However, the application of a thermocouple or any other sensing device is very likely to change significantly the temperature of the specimen, unless all aspects of the heat-transfer situation are carefully considered. The experimental stress analyst needing temperature measurements in regions of large temperature gradients must also become something of a heat-transfer analyst if he is to obtain valid data.
