Holloman High Speed Test Track Maglev project

The Holloman High Speed Test Track Maglev project is a long-term program to provide a new test capability for the DoD and the nation. The goal is to provide a low vibration environment for payloads on rocket-propelled sleds for speeds from subsonic to Mach 10. There are four demonstrative flight tests that will verify the Maglev project's sled levitation capability with superconducting magnets.

Flight Test 3 occurred on 5 April 2005 and demonstrated the current capability of sled levitation on the Maglev Sled Track. This demonstration used three HVAR (High Velocity Aircraft Rocket) motors for propulsion whereas Tests 1 and 2 used one and two HVAR motors, respectively. Test 3 accelerated the Maglev sled to 245 mph, 136 mph faster than Test 2 conducted in May 2004. Test 3 was conducted on a 350-meter guideway while Tests 1 and 2 were conducted on a 60-meter guideway. Test 3 also included the addition of laser sensors to detect vertical and lateral sled positions.

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.
