ABL Terms and Conditions
As part of recent performance testing of the flight laser module for the Air Force's Airborne Laser system, Team ABL -- USAF, Boeing, Northrop Grumman and Lockheed Martin -- demonstrated the performance of the exhaust system that will remove laser exhaust gases from the 747 aircraft.
Each module uses a "six-pack" of single tube ejectors (shown in photo) to "re-pressurize" laser exhaust from near vacuum levels inside the module to normal atmospheric pressure. This process allows the exhaust to be easily "pushed" out of the aircraft, similar to pushing a rock to the top of a hill and letting it roll down the other side under the force of gravity. Northrop Grumman leads the laser module integration and testing activities as part of Team ABL's $1.4 billion program definition and risk reduction contract with the Air Force Space & Missile Systems Center, Kirtland AFB, New Mexico.
