    Icing tests continue for Airbus A380 engine certification

    The U.S. Air Force's Arnold Engineering Development Center (AEDC) is currently performing a series of icing tests on the Engine Alliance (EA) GP7200 engine for the Airbus A380 commercial airliner. The EA is a 50-50 joint venture between GE Aircraft Engines and Pratt & Whitney. The prime objective for this particular test series is to get Federal

  • Tunnel 9 completes Falcon Hypersonic Test Vehicle testing

    The U.S. Air Force's Arnold Engineering Development Center's (AEDC) Tunnel 9 facility in White Oak, Md. is playing a crucial role in the ongoing Falcon program, with the completion of mission-critical testing of the Hypersonic Technology Vehicle 1 (HTV-1). The Falcon initiative is a joint Defense Advanced Research Projects Agency (DARPA) and Air
  • Pratt & Whitney’s F135 engine, the powerplant for the F-35 Joint Strike Fighter, is undergoing Initial Flight Release (IFR) altitude qualification testing in Test Cell C-1 in support of attaining approval to begin flight testing. This testing period, which marks the first time an F135 engine has been tested in the center’s Aeropropulsion Systems Test Facility (ASTF), represents a critical transition between the development and qualification phases of the overall F135 program.

    F135 engine testing begins in ASTF

    Testing of the Pratt & Whitney F135 engine in the U.S. Air Force's Arnold Engineering Development Center's (AEDC) C-1 test cell began Dec. 7, and represents a critical transition between the development and qualification phases of the overall F135 program. The engine is the powerplant for the F-35 Joint Strike Fighter (JSF). The primary objective
  • Dr. Steven Walker, Defense Advanced Research Projects Agency's (DARPA) deputy director of the tactical technical office, visited AEDC May 14 to get an update on hypersonic test facilities here and to brief center leadership on ongoing and planned hypersonic projects.

    DARPA official: AEDC 'critical' to hypersonics advancement

    As AEDC workers continue a 10-year, $63-million upgrade of the Aerodynamic and Propulsion Test unit, the Defense Advanced Research Projects Agency's deputy director for the tactical technical office visited Arnold May 14 to get an update on the hypersonic test facility they are slated to test in once it's fully operational.AEDC is critical in
  • 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
