7V SPACE CHAMBER

The 7V Space Chamber is a state-of-the-art deep space environment simulation test facility designed to test high performance interceptors and surveillance sensors at the conditions of deep space (20 K background). A spectral coverage can be provided over the visible to the LWIR spectral range and a radiometric calibration monitor system is located inside the chamber to allow accurate in-situ calibration of the 7V source systems that is traceable to the National Institute of Standards and Technology. 

Chamber 7V is configured to provide complete characterization and radiometric calibration of an infrared (IR) sensor in a single test facility and has the capability to perform all major categories of sensor characterization (flood source, point source, polarized source, spectral calibration, and mission simulation) during a single test entry. The chamber shares vehicle handling and target systems as well as support infrastructure with the 10V Space Chamber. 

An assortment of source systems allows evaluation of sensor performance over a wide range of target conditions. A 256x256 InSb camera, referred to as the Alignment Monitor System, is mounted on the chamber to provide independent source and background evaluation and target position calibration. The facility consists of a 7-foot-diameter by 21-foot-long chamber containing a full gaseous helium thermal shroud and an optically clean vacuum allows vibration isolation of the optical bench and all optical elements. The chamber is surrounded by a Class 100 Clean Room with an adjoining Class 1000 build-up area. 

The 7V Chamber has been used to support testing of airborne sensors, space-based sensors, and interceptor seekers. Since 1994, AEDC has performed more than 35 facility characterizations and sensor tests in the upgraded 7V Chamber.

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.
