Nose Fairing Modeling and Simulation to Support Trident II D5 Lifecycle Extension

Abstract

The objective of this thesis is to evaluate a modeling and simulation tool for the analysis of the Trident II D5 missile nose fairing to determine the limitations of serviceability through the extended service life of the D5 missile. The benefit of this analysis is a means to evaluate and manage the remaining nose fairing supply and serve as a baseline for future production of nose fairings. Constructed of a Sitka spruce and fiberglass laminate, the nose fairing is designed as the lifting point of the missile for submarine onloads and offloads and supports the entire weight of the missile. A computer model of the nose fairing was used to evaluate the nose fairing under tensile and compressive loading conditions to simulate the lifting evolution and closure segment impact at time of launch. Changes in the material properties of the model allow for a simulation of aging in the nose fairing to estimate the performance degradation over time, as well as exploration of the applicability of new materials to any future design of nose fairings.
