Abstract:
1. An aircraft forward pressure bulkhead comprising a malleable dome that is configured to deform in response to a predetermined threshold amount of impact energy caused by a foreign object strike, thus absorbing and dissipating at least a portion of the impact energy, said aircraft forward pressure bulkhead being void of any rigid non-deformable reinforcement members; wherein said malleable dome comprises a constant radius of curvature extending from a center portion to an outer edge portion, said malleable dome comprising a partial layer on a concave aft surface of said malleable dome, said partial layer being located around an outer perimeter of said malleable dome, said partial layer including the same said radius of curvature; said malleable dome further comprising at least one full layer on a convex side of said malleable dome and a second full layer coupled to said first full layer, said at least one full layer and said second layer having the same said radius of curvature; wherein said partial layer has a variable thickness that decreases towards the center of said malleable dome; and an outer chord coupled to said malleable dome around said outer perimeter, said outer chord providing a rigid attachment mechanism for said aircraft forward pressure bulkhead.
