摘要

Various theoretical and practical aspects, of a pressure-sensitive system for the measurement of gas temperatures in gas-turbine -engine combustion chambers are analyzed. An experimental setup was operated under controlled conditions, of temperature, weight' flow, and wall temperature. The gas temperature after com¬bustion was obtained by application of a relation equating thermo¬dynamic conditions before and after combustion. This method of gas-temperature sensing appears practical for high-temperature appli¬cations. The accuracy with which gas temperature may be' determined by this method is within ±2 percent. Measurements made by the thermodynamic method were used as a temperature standard for com-parison of temperature data obtained from conventional thermocouple probes.
