Dynamic Solutions For A Testing World AURORA TIP CLEARANCE Interactive Analysis of Dynamic Data Interactive Viewing Worldwide connectivity Aurora Tip Clearance is part of the Aurora Analysis system, an integrated analysis platform that provides all the tools and capabilities required for summary and detailed analysis of both time and frequency domain data from a single application window. Multifunction plot types The Aurora Tip Clearance application is used for processing the raw dynamic data (containing pulses which relate to blade passing events) to generate calibrated Tip Clearance processed files, which can be viewed and interrogated in the Aurora RawViewer module. Orbit plot Raw time series data (containing discrete pulses) are processed to produce Tip Clearance results files. Calibration curves are used to convert from DNS (mv) into Clearance (mm). Other features include:  Shaft Centreline processing Interactive viewing and cursor interrogation  Worldwide connectivity—Thin Client/ Server Architecture Multi function plot types Orbit plot with Shaft Centreline processing Tip Clearance files provide access to ‘real’ probe channels as well as ‘collated-pseudo’ blade channels—the probe channels are searched for all instances of events from Blade X which are then collated to form a new channel.

Dynamic Solutions For A Testing World The Aurora Tip Clearance application allows the user to submit tip clearance processing requests which are performed by the Aurora Tip Clearance Server. The Aurora Tip Clearance Server identifies each pulse in the raw data and extracts the height of the pulse. The pulse height in mV is then converted to clearance through the use of a calibration curve (also produced by the system). The processing by the Aurora Tip Clearance Server includes several algorithms and techniques for rejecting false pulses (that might be generated from noise spikes in the analogue front...
