Space Threat Assessment Testbed (STAT)

STAT is a ground test facility for evaluating the performance of materials, components, subsystems, and small satellites in a test environment capable of providing conditions from low Earth orbit to geosynchronous operations.

STAT simulates natural orbital environment conditions ranging from quiet to various geomagnetic effects generated as a result of solar activity that can impact space assets. Self-induced environmental conditions associated with space systems may also be simulated during testing to investigate potential system-level interactions.

Test chamber conditions and test article observables may be accessible to program sponsors for test article monitoring and control under varying simulated space conditions. Local support is available at Arnold Engineering Development Complex for test planning and execution, and to conduct analysis of test results.

Using the STAT test cell for Research, Development, Test & Evaluation (RDT&E) of materials, components, subsystems, and evolving technologies in a representative space environment can lower development costs and reduce the risk of failure of mission-critical assets. The ability to simulate multiple environmental effects under controlled conditions in a single instrumented chamber provides significant flexibility to support customer requirements. Rapid reconfiguration of test articles and adjustments in test chamber conditions further contribute to a cost-effective test regimen.

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.
