... such as power calibration test at low and high altitudes and Active Clearance Control (ACC) valve swing test at high power. As a result, the study proposes new methods to assess seal clearances using conventional pressure sensors at forward and aft cavities with the linear conversion curves. The conversion...

... test. As a result, it proposes new methods for tip clearances evaluation based on pressure measurement and conversion curves. New methods include one-point, two-points and three-points (or multi-) pressure measurement to assess clearance changes for different operating conditions. The conversion curves...
