  • From left to right, David Stanek, instrument technician; Roger Johnson, instrument technician; Josh Drumm, systems test engineer; Ed White, senior systems test engineer; Ricky Bush, outside machinist; and Aaron Wojcik, systems test engineer, at the Arnold Engineering Development Center’s 7V Space Chamber, remove an optical bench in the clean room at the seven by 21-foot test chamber. The bench’s removal is part of a major upgrade project that began with the chamber’s demolition by Western Environmental, Inc. The changes will not significantly affect the size of the facility. Some of the improvements to the chamber will include changing the airflow from horizontal to vertical and changing the chamber to a class 1,000 (number of particles per million) clean room.

    Major 7V space chamber facility upgrade underway

    A major upgrade to Arnold Engineering Development Center's (AEDC) 7V space chamber facility is underway. Demolition on the chamber's clean room began April 4, as part of a major upgrade project. The 7V chamber has been the primary sensor calibration facility at AEDC since the early 1970s. Significant performance and capability upgrades to the
  • Northrup Gruman Model Technician Dale Metzler installs a dummy store on a 15 percent F-35 Joint Strike Fighter model during a model change. The JSF is being tested in the Arnold Engineering Development Center’s 4-foot transonic wind tunnel.

    AEDC supports JSF program with store separation test

    An Arnold Engineering Development Center test team and their Lockheed Martin customer are currently testing the F-35 Joint Strike Fighter in the center's 4-foot transonic wind tunnel to evaluate separation of weapons from the aircraft while in flight, helping keep the Joint Strike Fighter (JSF) program on track to meet initial production in 2006.

    Tennessee plays an important role in the nation's space program

    The 2005 Tennessee Space Week runs Jan. 23-29 this year providing an opportunity for students and parents alike to learn of the Volunteer State's role in space exploration. The U.S. Air Force's Arnold Engineering Development Center remains at the center of that effort today providing essential testing for our nation's, and the world's, ongoing

  • AEDC contractor award fee announced

    The Air Force has announced the award fee for the Arnold Engineering Development Center's support contractor, Aerospace Testing Alliance (ATA) , for the period Oct. 1, 2006 through April 30, 2007. The award fee determining official, Yvonne Jackson, deputy program executive officer for Combat and Mission Support, Office of the Assistant Secretary of
  • AEDC employee Cindy Yates with a Minuteman ICBM upper stage rocket motor Jan. 10. As a safety precaution, she is using a hand brake to prevent the motor from rolling out of control on AEDC’s new rocket rail transport system that improves the process for moving motors into position to be prepared for testing.

    AEDC improves solid rocket motor test process

    Moving a seven-ton rocket motor loaded with explosive fuel can be a tricky proposition, but that task just became easier, safer and more efficient at Arnold Engineering Development Center (AEDC). Jan. 10, AEDC employees used a new transport system to move two such rocket motors - stage two and stage three motors for the Minuteman intercontinental
  • ATA Outside Machinist Larry Towry speaks through a microphone to test personnel in the AEDC’s 16-foot transonic wind tunnel (16T) control room who are operating the metal arm, or sting, with a wing store above the A/E-18G model. Towry is ensuring the 16T control operators do not damage the wing store or aircraft model during subsequent testing by exceeding “touch points” of contact between the components.

    Future EA-18G undergoes store separation testing at AEDC

    Arnold Engineering Development Center (AEDC) has conducted 64.5 air-on hours of store separation testing to support development of the U.S. Navy's next generation electronic warfare aircraft, the EA-18G. The EA-18G, an electronic attack version of the F/A-18E/F aircraft, is the planned replacement for the Navy EA-6B Prowler, in service since 1971.
  • Carey Wofford, Aerospace Testing Alliance outside machinist, speaks to test personnel in the center’s 16-foot-transonic wind tunnel control room who operate the Captive Trajectory Support (CTS) mechanism holding a HARM missile model above the inverted F/A-18E/F Super Hornet model during a store configuration change.

    Navy fighter tests conducted in AEDC's 16-foot transonic tunnel

    Arnold Engineering Development Center (AEDC) has completed a complex store separation test for the U.S. Navy's F/A-18 E/F Super Hornet in the center's 16-foot transonic wind tunnel (16T). "The purpose of our continuing wind tunnel testing is to certify the F/A-18E/F aircraft to carry new weapons," said David Hughes, Aerospace Testing Alliance
  • A Pratt & Whitney F135 engine, one of two engines slated to power the F-35 Lightning II, undergoes altitude testing at AEDC. AEDC is conducting a multi-year test program worth approximately $200 million in several test facilities for variants of the F135 engine.

    AEDC engineers played vital role in F-35 initial flight

    Friday's initial flight of the new F-35 Lightning II Joint Strike Fighter (JSF) came after more than six years of development and testing at Arnold Engineering Development Center. Center engineers have tested the new weapon system using various scenarios and flight conditions. The F135 engine and wind tunnel models of the aircraft have logged more
  • Brian Hale, an ATA instrument technician at AEDC’s Precision Measurement Evaluation Laboratory, installs a flow meter onto the flow bench for calibrating.

    One-of-a-kind flow bench is operational again at AEDC

    Arnold Engineering Development Center's (AEDC) Precision Measurement Equipment Laboratory (PMEL) recently brought a unique liquid flow calibrator back into service. The large machine, a prototype, is used to calibrate liquid flow meters found in test cells on base and throughout the Air Force and also overseas. Troy Holland, an Aerospace Testing
  • This five-percent scale model of the F-15E Strike Eagle and Joint Air-to-Surface Standoff Missile (JASSM) was used to conduct store separation testing in Arnold Engineering Development Center’s four-foot transonic wind tunnel.

    AEDC breaks new ground in improvements to U.S. long-range strike capabilities

    Arnold Engineering Development Center (AEDC) "flew" the Joint Air to Surface Standoff Missile (JASSM) on the F-15E Strike Eagle for the first time during a test that concluded in September.
