107.1 Tip Timing for Use in Gas Turbine Engines


The purpose is to develop a standard for gas turbine instrumentation used to measure blade tip deflections during engine operation.


The scope is to standardize the application of tip timing instrumentation including the acquisition and data processing of tip timing data. The object of the specification is to provide common tools and agreed methods for testing different systems to the same standard.
