    With funding from the Air Force Small Business Innovation Research Program, Applied University Research developed the Near Field Velocity Measurement System, which is able to measure local air velocity around wind tunnel test articles that they put into large-scale wind tunnel facilities at Arnold Engineering Development Complex. The technology looks at light that’s scattered off of small droplets of mineral oil that are injected into the moving air. That light goes into a detection system that analyzes that light and determines what the air velocity is, by assuming that the air velocity is the same as that particle velocity.

    The technology provides extra information to customers that are using AEDC wind tunnels. Those customers can better understand what the flow field is around their test articles that models weapon systems that they will be providing to the Air Force in the future. By knowing that detailed information early on in the acquisition cycle, the Air Force can avoid problems that might develop later in the acquisition cycle, which are very expensive problems to fix.
