Aft pressure bulkheads can either be curved, which reduces the amount of metal needed at the cost of reducing the usable space in the airliner, or flat, which gives more internal space but also more weight. A bulkhead is a software design technique that divides code into independently deployable units such as microservices. Secondly, losing strength of bulkheads. I. Landlubbers call it 'a wall.' 10% slower than 737 The conical shape would require serious stiffeners to survive pressurization cycles for the whole life of the aircraft; the bulkhead solves this problem by using a shape that is naturally more resistant to stresses - and thus can be built with less material - leading to less weight, and hence fuel savings (in addition to the increased safety). A literature review was first conducted in order to improve the knowledge on topology optimization. Design.
