Aperture systems are a unique enhancement to an aircraft hangar or retro-fit project. Configurations commonly consist of a three part system where part of the plane's fuselage and tail are exposed on the exterior of the hangar. Door Engineering can provide several custom fabricated aperture designs to meet your project requirements with options such as power-operated pressure sensing panels, rotating panels for several different fuselage profiles and closure doors when the aperture system is not in use.
