Major design changes to the Propulsion Gas Turbine Air Inlet on the US Navy's CG47 Class Guided Missile Cruisers have resulted in significant superstructure weight savings. The majority of weight reduction resulted from use of finite element analysis (FEA) computer modeling techniques applied to structural optimization. FEA models of the forward and aft deckhouses provided the necessary capability to analyze each structure's response to loads simulating a nuclear air blast, shock, and vibration. Integration of the moisture separator housings into each deckhouse structure allowed improved structural stability and additional weight reductions. FEA modeling and a redesign of the major inlet system 32 % lighter than inlets installed on early ships of this class. The first of the lightweight deckhouses has been installed on the CG52 Cruiser.
