Sponsor Naval Sea Systems Command (Navy)
Summary The Naval Postgraduate School has been a leader in the underwater shock explosion field for a number of years. The current work proposed here implements the techniques developed during previous ship shock efforts in prior ship classes while extending the M&S field into new areas such as multi-hull ship structural response. The main objectives of this proposal are as such: (1) To perform FEM modeling of the two hull variants of the LCS Class in support of the required vulnerability and survivability analysis, including underwater explosion testing and ship shock trials. (2) To identify potential problem areas as related to the survivability of the LCS hull variants as designed in Flight 0 based on near field shock phenomena such as whipping. (3) To conduct complementary investigations along the way with respect to the use of the air gun and/or alternative shock methods, as required by sponsor. (4) Provide input and support on LCS Shock Management Plan as directed in support of the scheduled FY 14 LCS class ship shock trials.
