ABSTRACT:
An aircraft pressure containment module is adapted to be mounted generally transversely within an aircraft fuselage for providing pressure containment to separate pressurized and non-pressurized sections of an aircraft. A plurality of web segments are joined together to form a web member. A ring member is arranged on a first pressurized side of the web member. A plurality of truss assemblies are also arranged on the first side of the web member. Each truss assembly is comprised of a first truss member adapted to extend outwardly from the ring member to a peripheral edge of the web member. The first truss member is joined to the web member and joins together adjacent web segments. A second truss member extends from the first truss member in a direction generally normal to the first side of the web member. The second truss member is adapted to be joined to an aircraft fuselage in a longitudinal sense or it may comprise a portion of longitudinally extending member of the fuselage such as a stringer. A third truss member is joined to the second truss member and the first truss member to form a truss assembly having at least in part a generally triangular shape. The truss assemblies are adapted to react pressure loading from the web member to the fuselage of an aircraft in a manner similar to a conventional dome type pressure containment module. An aircraft using the module has an elongated fuselage extending in a longitudinal direction and the pressure containment module mounted generally transversely within the fuselage.
