Zusammenfassung:Embodiments for hybrid pressure deck (200) of an aircraft. One embodiment is a pressure deck disposed over a main gear wheel well of an aircraft. The pressure deck includes longitudinal beams (204) extending in a forward and aft direction between an aft wheel well bulkhead (128) and a rear spar (126) of the aircraft. The pressure deck (200) also includes a web (220) attached to an underside of the longitudinal beams. The web includes a flat web portion (221) supported by transverse stiffeners extending in an inboard and outboard direction, and a curved web portion (222) including arches configured to flex laterally from load in the inboard and outboard direction. A transition between the flat web portion and the curved web portion extends at least partially in the forward and aft direction of the aircraft.
