Abstract
In order to control engine operation by exhaust gas measurement, while avoiding operating conditions that exceed the safe maximum temperature limit, a gas turbine engine (10) includes a thermocouple temperature probe (28). The gas turbine engine (10) has a rotary compressor (12), a turbine wheel (14) coupled to the compressor (12) for driven movement thereof, and an annular nozzle (16) proximate the turbine wheel (14) for directing gases of combustion at the turbine wheel (14). It also includes an annular combustor (18) defining an annular combustion space (20) disposed about the turbine wheel (14) and in fluid communication with both the compressor (12) and the nozzle (16). The combustor (18) receives fuel from a source and air from the compressor (12) and it combusts fuel and air in the combustion space (20) to generate the gases of combustion. It further includes an exhaust duct (22) leading from the turbine wheel (14) for exhausting the gases of combustion generated in the combustion space (20) after the gases of combustion have been directed at the turbine wheel (14) by the annular nozzle (16). The exhaust duct (22) directs the gases of combustion axially away from the turbine wheel (14) substantially centered about a centerline (26) thereof. With this arrangement, the thermocouple temperature probe (28) is adapted to measure a mean temperature for the gases of combustion substantially at the centerline of the exhaust duct (22).
