DYNAMICS OF LIQUID-FILLED SHELL: AIDS FOR DESIGNERS
Abstract
Ballistic Research Laboratories Memorandum Report 1477 (Karpov, May 1963) AD-410 484 includes a discussion of Stewartson's stability analysis of liquid-filled projectiles, and 'Tables of Poles and Residues' needed for quantitative design use of the analysis. Various design problems show that an extended tabulation is needed, and the present report provides this extension. The new tabulation (Appendix B) covers a nondimensional frequency range of 0.00 to 0.70 in increments of 0.02 and a range of cavity fill ratios of 20 to 100 percent in maximum increments of ten percent. A brief description of Stewartson's analysis is also given in the report. Emphasis is placed on the physical significance of the assumptions and results of the theory rather than its mathematical detail. The intent is to provide the novice designer of liquid-filled shell with an appreciation and first working knowledge of the analysis. Additionally, the summary of the theory is used to point out the significant advances that have been made in understanding liquid-filled shell problems since the publication of Ballistic Research Laboratories Memorandum Report No. 1477.
