The Anti-Roll Stabilization of Ships by Means of Activated Tanks. Part C. Synthesis of High Performance Systems

Abstract

Part C presents a theoretical investigation of high-performance ship-stabilization systems, principally systems using U-tube tanks. Starting from the results of Part A, and using standard servo methods, we proceed to find systems with greater and greater effectiveness (for a given capacity). It appears that tank systems using inertia effects, may be as rapid in response as any other known stabilization systems. The results indicate that as long as the system's capacity is not exceeded, it should be possible to achieve greater than 90% stabilization. The three factors in ship stabilization: regulated elements; regulating elements; and the input, are discussed in turn, using appropriate servo methods and concepts. This part of the report provides considerable grounds for believing that high-performance stabilization systems using tanks (and presumably other devices) can be achieved. It shows rational techniques by which such stabilization systems may be designed, and indirectly it emphasizes the inherent difficulties in design procedures which do not utilize servo techniques.
