The first image shows the global heating data acquired on the windward surface of the vehicle during a continuous pitch sweep with both inlets started. In the second image the color changes represent the global heating data acquired on the windward surface of the vehicle during a continuous pitch sweep with the starboard inlet unstarted.

ARNOLD AIR FORCE BASE, Tenn. — Nickolas Galyen, an engineer in Aerospace Testing Alliance’s Integrated Test and Evaluation department, aligns a calibration target during a series of tests to validate the use of stereo particle image velocimetry (PIV) in the 4-foot transonic wind tunnel at Arnold Engineering Development Center. Images of the precisely machined target are used to spatially calibrate particle images to measure three-dimensional velocity airflow fields. (Air Force photo by David Housch)

ARNOLD AIR FORCE BASE, Tenn. (AFMCNS) -- Adam Plondke, store separation project engineer, inspects the installation of the 1/20-scale model of the Miniature Air-Launched Decoy and F-16. Wind tunnel testing, which investigated the carriage and separation characteristics of the MALD from the F-16 at speeds up to Mach 0.95, was recently completed in the 4T wind tunnel. Use of the low-cost, air-launched, programmable decoys, which can accurately replicate the combat flight profiles and signatures of U.S. and coalition aircraft, is designed to deceive and confuse adversary air defense systems.
