The U.S. Air Force’s Arnold Engineering Development Center (AEDC) successfully test-fired an ORBUS 1A rocket motor under simulated high-altitude conditions at the center’s J-6 Large Rocket Motor Test Facility, providing critical support for the second and third stage power plant of the Missile Defense Agency’s (MDA) Ground-Based Interceptor (GBI) missile.
The GBI is the weapon component of the Ground-Based Midcourse Defense system, and is the long-range interceptor of the overall Ballistic Missile Defense System (BMDS). The BMDS is an integrated, “layered” system for defending the homeland, our deployed forces overseas and our allies from ballistic missiles of all ranges, during any phase of their flight-boost, midcourse and terminal. The BMDS now in development will consist of ground and sea-based interceptors, a directed energy aircraft (Airborne Laser) and numerous radars and sensors integrated with a command, control, battle management and communication infrastructure.
The GBI’s payload will be an Exoatmospheric Kill Vehicle equipped with a high-sensitivity infrared seeker and an agile-divert system to support the intercepts of threats at very high closing velocities. This is a “hit-to-kill” technology that uses only the force of a direct collision with the target missile warhead, using no explosives. A number of GBI’s are currently deployed in Alaska and California in preparation for beginning defensive operations after on-going training, rules of engagement development and additional testing are complete.
The GBI missile’s second /third stage rocket motor, built by Alliant Techsystems (ATK) in Elkton, Md. , underwent the qualification testing because the company recently took over the production of the upper-stage components of the GBI missile from Pratt & Whitney.
“The ORBUS motor has been around for quite a long time,” explained 2nd Lt. Timothy Higley, a test project manager for the space and missiles division at AEDC. “It’s not a new system; it’s basically being revised and reused for the GBI. Now that they (ATK) are beginning to build these motors, they have to be qualified as a vendor to verify they can reliably produce these motors and meet all the specs.”
He added, “This (rocket motor) is the first one of its type we’ve tested in J-6. Previously, during the 1990s, we had performed qualification testing on an earlier version of this rocket motor in AEDC’s rocket development test cell J-5.”
Lieutenant Higley said the reasoning behind the change of testing location is the system at J-6 is a better facility from both a performance and safety standpoint.
“J-6 is a newer rocket testing facility,” he said. “It’s larger, has a significant blast wall, the increased distance from other buildings at the Center, as well as some improved features inside the test cell, including the ability to pump down the pressure and isolate it from the plant.”
Editorial Note:
Arnold Engineering Development Center is the nation's largest complex of flight simulation test facilities. The center was dedicated in June 1951 by President Harry Truman and named after 5-star General of the Air Force Henry 'Hap' Arnold, visionary leader of the Army Air Forces in World War II and the only airman to hold 5-Star rank. Today, this $7.8 billion complex has some 58 aerospace test facilities located at Arnold Air Force Base, Tenn., and the center's remote operating location Hypervelocity Tunnel 9 in White Oak, Md. The test facilities simulate flight from subsonic to hypersonic speeds at altitudes from sea level to space. Virtually every high performance flight system in use by the Department of Defense today and all NASA manned spacecraft have been tested in AEDC's facilities. Today the center is testing the next generation of aircraft and space systems. For more information on AEDC visit the center's Web site at www.arnold.af.mil
Sikorsky announced the expansion Tuesday of its existing The Sikorsky technical integration center will grow from 10 to 60-plus employees later this year to include engineers, logisticians, and program managers. New positions are to be filled predominantly by new hires from the local area.
"We're in the early phase of the new UH-60M model of the Black Hawk,'' said Ed Steadham, a spokesman for Sikorsky. "In the meantime, there are about 1,600 Army aircraft in the field that need constant support. It makes a lot of sense to be close to the customer, and we know The U.S. Army Aviation and Missile Command is at Redstone Arsenal.
Sikorsky will initially expand its "Expansion of our Huntsville presence is evidence of our continuing commitment to provide world-class engineering and logistics expertise to support the U.S. Army Aviation warfighter,'' said Mark Miller, Sikorsky vice president for engineering.
Sikorsky also has operations in Since 1978, Sikorsky has manufactured and delivered more than 1,500 H-60 Black Hawk helicopters to the Army. The expanded Sikorsky Huntsville office will support the legacy Black Hawk fleet as well as the latest version of the aircraft, the UH-60M advanced utility helicopter.
