12V SPACE CHAMBER

The 12V Chamber is a 12-foot-diameter by 35-foot-high thermal vacuum test facility with solar simulation capability. The facility contains a full liquid nitrogen thermal shroud and has an optional gaseous helium inner liner that can be cooled down to 10 degrees Kelvin. The solar simulator is an off-axis system with xenon arc lamps that uses integrating assemblies to collimate a uniform, 1-solar constant beam over an 8-foot-diameter by 8-foot-high test volume. The chamber can also be configured for electric propulsion thruster plume analysis and integration effects testing. 


CAPABILITIES
Thermal Control:  Chamber is completely lined with a liquid nitrogen shroud that can provide thermal conditions down to 77 degrees Kelvin. Optional 10-degrees Kelvin gaseous helium liner available upon request. 
Vacuum Range:  ≤1x10-7 Torr (with gaseous helium shroud) to local atmospheric pressure.
Working Volume:  12-foot diameter x 35-foot high.
Pumping System:  Mechanical roughing pumps, blowers, and single 36-inch diffusion pump, all with cryogenic traps. Upgrade to clean cryogenic high vacuum pumps planned.
Loading:  Horizontal: 6-foot manway. Vertical: 10-foot cap at top of chamber.
Cold Wall:  Full liquid nitrogen cryogenic shroud. Optional 10-degrees Kelvin gaseous helium liner available upon request.
Special Features:  Quartz xenon arc lamp solar simulator system.
Data:  All facility data time tagged and archived.
Work Areas:  Test customer offices available. Limited hardware storage available.
Solar Simulation:  Off-axis system with xenon arc lamps that use an integrating lens assembly to collimate a uniform, 1-solar constant beam over an 8-foot-diameter by 8-foot-high test volume.
Electric Propulsion:  In the EP configuration, the cell pressure during thruster operation can be maintained at or below 10-6 Torr, with a xenon pumping speed exceeding 2,000,000 liters/sec. Plume Diagnostics with Langmuir Probes and Radio Frequency Horns are available.

LANDING GEAR TEST FACILITY

Overview

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.
