Measurement of unsteady gas temperature with optical fibre Fabry-Perot microsensors
We describe the application of thin-film optical fibre Fabry-Perot (FFP) microsensors to high-bandwidth measurement of unsteady total temperature in transonic gas flows. An aerodynamic probe containing two temperature sensitive FFP microsensors was deployed in the rotor exit flow region of a gas tur...

| description | We describe the application of thin-film optical fibre Fabry-Perot (FFP) microsensors to high-bandwidth measurement of unsteady total temperature in transonic gas flows. An aerodynamic probe containing two temperature sensitive FFP microsensors was deployed in the rotor exit flow region of a gas turbine research rig. Measurements reveal gas temperature oscillations typically 4 K peak to peak at the blade passing frequency of 10 kHz with components to the third harmonic detected in the power spectrum of the temperature signal. |
