Abstract
A pressure bulkhead may include a bulkhead wall having a radially inner disk and a radially outer compression ring, the outer compression ring being reinforced to balance meridional and hoop stresses sustained by the bulkhead wall in response to a pressure differential across the pressure bulkhead; and the radially inner disk being unitary with the outer compression ring and being made of the same material as the outer compression ring.
Claims20
A pressure bulkhead comprising:
- a dome-shaped bulkhead wall having a radially inner disk and a radially outer compression ring, the outer compression ring being reinforced to balance meridional and hoop stresses sustained by the bulkhead wall in response to a pressure differential across the pressure bulkhead;
- and
- the radially inner disk being unitary with the outer compression ring.
A pressure bulkhead comprising:
- a dome-shaped bulkhead wall having a substantially uniform thickness attached to one or more doubler rings at a periphery of the bulkhead wall that is sufficient to balance meridional and hoop stresses sustained by the bulkhead wall in response to a pressure load applied to the bulkhead wall.
A method of mounting a pressure bulkhead in an aircraft, the method comprising:
- affixing to a fuselage skin of the aircraft an attachment ring having an inner band and an outer band defining a concave surface such that the concave surface is directed toward a non-pressurized section of the aircraft when the aircraft fuselage skin is under a pressure load;
- and
- attaching an outer periphery of a bulkhead wall to the attachment ring, the bulkhead wall having a radially inner disk and a radially outer compression ring, the outer compression ring being of sufficient strength to balance meridional and hoop stresses sustained by the bulkhead wall in response to a pressure load applied to the bulkhead wall.
