Claim 5:
6. A pressure deck disposed over a main gear wheel well of an aircraft, the pressure deck comprising:
longitudinal beams extending in a forward and aft direction between an aft wheel well bulkhead and a rear spar of the aircraft, the longitudinal beams spaced from each other in an inboard and outboard direction between wheel well longeron beams at either side of body of the aircraft to form a middle bay, intermediate bays, and outboard bays; and
a web attached to an underside of the longitudinal beams and the wheel well longeron beams, the web including a flat web portion supported by transverse stiffeners extending an inboard and outboard direction, and a curved web portion including arches configured to flex laterally under load in the inboard and outboard direction,
wherein a transition between the flat web portion and the curved web portion extends partially in the forward and aft direction of the aircraft,
wherein the flat web portion is disposed in the middle bay and the outboard bays to react side loads,
a width of the flat web portion is full along the aft wheel well bulkhead and narrows toward a longitudinal center at the rear spar, and
wherein a combination of the flat web portion and the curved web portion is disposed in the intermediate bays to provide flexibility at an intersection of the rear spar and the pressure deck.
