Software That Monitors Rotating Machinery for Failures

The Air Force’s Arnold Engineering Development Complex (AEDC), one of the largest flight simulation test facilities in the world, is home to a host of rotating machinery—most notably the equipment that drives Arnold’s five active wind tunnels. Those tunnels, used for a wide variety of testing and evaluation procedures, are activated on an unpredictable schedule, increasing the need for solutions that automatically monitor system health on an ongoing basis. Working with AEDC officials under a series of Air Force Small Business Innovation Research (SBIR) contracts, Mechanical Solutions Incorporated (MSI) developed software that can continuously monitor sensors on the machinery and identify potential problems before failures occur.

MSI’s SBIR contracts formed the baseline for developing and commercializing the firm’s Sentry™ software—another example of the many successful innovations enabled by the US Air Force’s SBIR and Small Business Technology Transfer (STTR) programs. For more information, visit
