PC-SIGNAL: PC-Based Dynamic Signal Analysis Software 

AI Signal Research, Inc

Huntsville, AL

• PC-SIGNAL™ ,a post-process dynamic signal analysis software for rotating machinery, offers dramatic time savings by eliminating the programming effort formerly needed for sophisticated signal analysis.
• PC-SIGNAL simplifies all aspects of the signal processing operation with its effective graphical user interface and expedites all steps¾from importing raw signal data files, through choice of processing algorithm, to outputting the results.

• Development stage: PC-SIGNAL™ commercial version available.
• Other than its general capability for spectral/waveform analysis, PC-SIGNAL includes many specialized signal analysis techniques for rotating machinery diagnostics that are useful for engine/ machinery diagnostic evaluation, bearing/gearbox and drive train signature analysis, and vibration signature enhancement and identification. The SBIR/STTR-funded research culminated with the effective demonstration of PC-SIGNAL on NASA's Space Shuttle Main Engine (SSME) fault diagnostic and anomaly resolution.

• Primary target/potential market sectors: aircraft/helicopter industries, rocket engine manufacturers, transportation industry, nuclear power industry.
• Unique competitive advantage: novel signal analysis techniques and easy-to-use interface software allow engineers to perform vibration analysis with a very cost-effective system.
• Major aerospace firms have purchased licenses for engineering use in product support of rocket engine product development.
   

• U.S. Army Redstone Technical Test Center uses PC-SIGNAL for vibration data processing and analysis in support of all its weapon system test programs.
• NASA MSFC propulsion engineers are using PC-SIGNAL as a diagnostic tool in Shuttle propellant flow liner failure investigation.
• U.S. Air Force Research Laboratory uses the program for vibration analysis of engine tests.
