Case highlight: Hangar door protects world's largest aircraft /global/scaled/5616x2443x0x0x1000x435/AAES-OW2-AAES.com-News-Images-2015-StratolaunchSystems-aviation-5616x3744px.jpg When the world’s largest aircraft needed protection from the harsh conditions of the Mojave Desert, a Megadoor hangar door from ASSA ABLOY Entrance Systems was selected to do the job. The world's largest aircraft, SpaceShipOne, has a wingspan of 380' (116m) and thrust provided by six 747 air-craft engines. It is housed at Stratolaunch Systems in Mojave, California. In order to protect the aircraft from the harsh dessert environment the customer chose the Megadoor hangar door solution for aviation. The unique perimeter seals and low air infiltration make the vertical-lifting Megadoor hangar door an ideal chose for the hangar’s unique requirements. Furthermore, it does not require a bottom rail system which would collect sand and dust and require regular cleaning. Better ventilation The hangar doors at Stratolaunch Systems have to be closed during normal operation for privacy, protection against the environment, and access control. The facility uses a combination of exhaust fans and evaporator coolers to increase worker comfort and indoor climate in the hot desert summers. Four massive exhaust fans were incorporated into the hangar door system to provide ground level air movement, to complement the fans on the top of the hangar on the opposite wall. Increased natural light The hangar door system provides increased natural light by using a translucent fabric. The soft, diffused light creates a better work environment for the technicians while reduces energy costs.
