TRW Aeronautical Systems has been awarded a contract by Northrop Grumman Corporation’s Integrated Systems sector to supply the drive system for the weapons bay doors on the Joint Strike Fighter (JSF).
The contract is said to cover the systems development and demonstration phase (SDD) and is valued at $21 million, with the expected total programme value to exceed $650 million.
The first hardware is scheduled to be delivered in 2004. Northrop Grumman, a principal member of the Lockheed Martin JSF team, is responsible for integration of the centre fuselage and weapons bay door drive systems as part of its work share.
The JSF has two weapons bay doors, one on either side of the aircraft. Each bay door is operated by independent geared transmission systems driven by hydraulic power drive units.
The operation of each door is controlled by an electronic control unit, which receives its commands from the vehicle management computer.
An international team led by Lockheed Martin is under contract to develop the JSF for the United States Air Force, Navy and Marine Corps.
The United Kingdom, Royal Air Force and the Royal Navy, Canada, Denmark, the Netherlands, Norway and Italy and Turkey have also joined the programme.
