High Response Data Acquisition System,
Abstract
High response instrumentation is used frequently in gas turbine engine testing to determine the transient and dynamic behavior of various engine and component parameters. The Naval Air Propulsion Center (NAPC) enhanced its data acquisition and analysis capability in April 1983 with a new digital high response data acquisition system which eliminated many of the problems inherent with older analog data acquisition and analytical methods. This system has the capability of acquiring multiple parameters simultaneously at an aggregate sampling rate of up to 48,000 samples per second with online digitization and real time recording on a private data disk. The NAPC offline data analysis system provides same-day access to the data with the capability to display the data in various tabular and graphical formats. Analytical techniques available include time zero analysis, high pass, low pass, and band pass digital filtering, and power spectral density analysis using fast fourier transformations.
