摘　　要：针对远海核应急救援需求,研发设计专用于两栖飞机投送的核应急快速响应无人艇(核应急救援方舱)非常必要.研究确定了方舱主尺度及船型参数;计算了正浮、倒浮和横倾90°典型浮态下的静水力特性曲线,并绘制了初稳性随重心高度变化的曲面图谱,确定不同吃水下的极限重心高度;提出了方舱稳性计算基本原理和自扶正计算流程,绘制了满载工况和空载工况下静稳性曲线图谱,并讨论了自扶正性能随重心高度变化规律.通过样条曲线拟合,得到满足自扶正要求的最大重心高度.研究成果可为方舱后续设计提供技术基础和参考.In view of the demand for nuclear emergency rescue in distant seas, it is necessary to develop and design a nuclear emergency rapid response unmanned surface vehicles(nuclear emergency rescue shelter) specially designed for amphibious aircraft delivery. So the main dimensions and hull parameters of the shelter are researched and determined;the hydrostatic performance curves under the typical floating cases of positive float, inverted float and 90° transverse heel are calculated, and the surface diagrams of the variation of the initial stability with the height of the center of gravity to determine the height of the center of gravity maximum or minimum limit under different drafts are drawn;the basic principle of stability calculation and self-righting calculation process are proposed, the hydrostatic stability curve plots under full load and no-load conditions are given, and the variation law of self-righting performance with the height of the center of gravity is discussed. The maximum height of the center of gravity that meets the requirements of self-righting is obtained through spline curve fitting. The research results can provide a technical basis and reference for the subsequent design of the shelter.
