Verifying data integrity of electronically scanned pressure systems at the NASA Glenn Research Center

The proper operation of the Electronically Scanned Pressure (ESP) Systems at the NASA Glenn Research Center is critical to accomplish the following goals; acquisition of highly accurate pressure data for the development of future aerospace and commercial aviation systems and continuous confirmation of data quality to avoid costly, unplanned, repeat wind tunnel or turbine testing. Standard automated setup and checkout routines are necessary to accomplish these goals. Data verification and integrity checks occur at three distinct stages, pre-test pressure tubing and system checkouts, daily system validation and in-test confirmation of critical system parameters. This paper will give an overview of the existing hardware, software and methods used to validate data integrity.
