Decommissioned Mach 8 tunnel removed to make room for future test opportunities

Marshall Brown, a former AEDC engineer, checks a model suspended in the Tunnel E wind tunnel at Arnold Air Force Base in January 1972. In Tunnel E, a magnetic model support system (MMSS) was used, which eliminated the need for strut or sting supports that generated unwanted disturbance in the wakes of the model. Models weighing up to 20 pounds could be tested with the MMSS. (U.S. Air Force photo)

Missionized tire wear testing helping tire designers fail fast to move forward

The 3D scanner used by the Landing Gear Test Facility team to scan runways is shown in use. The scans are used to digitally model the runway surface for analysis and ultimately to additively manufacture surfaces for Missionized Tire Wear Testing. (Courtesy photo)

Missionized tire wear testing helping tire designers fail fast to move forward

Additively manufactured tiles produced by Open Additive, such as those shown, for use in the 168-inch internal drum dynamometer at the Landing Gear Test Facility, or LGTF, at Wright-Patterson Air Force Base, Ohio, are being developed and produced through a Small Business Innovative Research contract. A complete usable tile for use in the dynamometer is expected within the year. (Courtesy photo)

Missionized tire wear testing helping tire designers fail fast to move forward

A tire undergoes Missionized Tire Wear Testing in the 168-inch internal drum dynamometer at the Landing Gear Test Facility, or LGTF, at Wright-Patterson Air Force Base, Ohio, with concrete tiles installed to simulate a specific runway surface. The concrete tiles are created by taking molds of a runway then casting the tiles. The dynamometer operates at speeds up to 350 mph, with loads of up to 150,000 pounds, plus or minus 20 degrees of yaw, plus or minus 10 degrees of camber and can provide variable levels of brake torque.
