MARK 1 TEST FACILITY

The Mark 1 Test Facility is a state-of-the-art space environment simulation test chamber for full-scale space systems testing. A $1.5 million dollar upgrade in fiscal year 2000 replaced existing oil diffusion pumps with a complete dry pumping system, cleaned the interior of the chamber and refinished the surface the (LN2) thermal shroud. A new Hewlett Packard 3852, with 1,500 channels of data capability, replaced the previous Micro-Vax data system. These upgrades, combined with the shear size of the facility, at 42-foot-diameter by 82-foot, postures AEDC for future testing of full-scale satellites and other space systems requiring a contamination-free test environment.

LANDING GEAR TEST FACILITY

The Landing Gear Test Facility (LGTF) has been a cornerstone of aerospace testing at Wright-Patterson Air Force Base since 1942, dedicated to ensuring the reliability and performance of aircraft landing gear systems.

Throughout its history, the LGTF has supported the warfighter by providing critical data to enhance the safety and effectiveness of landing gear, wheels, tires, and brakes, directly contributing to the mission of the United States Department of Defense. In addition to its military focus, the LGTF offers comprehensive testing services to commercial entities, employing world-unique test machines capable of simulating real-life conditions with unparalleled accuracy.

Guided by the core values of Integrity, Service, and Excellence, the LGTF consistently delivers precise and dependable data to both military and commercial partners.
