Dynamic Solutions For A Testing World Overview AURORA TORSION Interactive Analysis of Shaft Twist Data • Interactive viewing Worldwide connectivity • Multifunction plot types • Smoothing option • FFT Analysis option Aurora-Torsion 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. The Aurora-Torsion application processes pulse event data from probes either end of the engine shaft, using the difference in time of arrival of pulses to calculate the twist of the shaft. Calibrated Torsion processed files are generated which can be viewed and interrogated in the Aurora-RawViewer module. Characterisation for absolute twist analysis Twist and/or Torque processing can be carried out.

Dynamic Solutions For A Testing World Users can submit Torsion processing requests which are performed by the Torsion server. The user specifies whether they wish to perform Torque processing in addition to the Twist processing and which method of Torque computation to use. Characterisation of the channel data for pulse identification/ numbering is used within the system to reference the Twist/ Phase for a selection of manoeuvres in an engine run to a common zero. The aim of characterisation for pulse identification is to allow the user to process a range of manoeuvres in a period of engine running...
