Hangar doors from ASSA ABLOY Entrance Systems were specified to protect the world’s largest aircraft in Stratolaunch Systems in Mojave California.

In order to protect the SpaceShipOne aircraft from the harsh desert environment with its fine dust and sand which could affect sensitive aviation electronics, engines and other aircraft components, the customer chose a hangar door solution from ASSA ABLOY Entrance Systems.

Unique perimeter seals and low air infiltration values make the Megadoor hangar door a more effective and more suited to the job than a traditional sliding hangar door. Furthermore, it does not require a bottom rail system which would collect sand and dust and require regular cleaning.

The doors have to be closed during normal operation for privacy, access and control of the environment. 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.

The door system increases the day-light in the hangar by using a translucent fabric. The soft, diffused light creates a better work environment for the technicians and reduces lighting costs.
