海上快速救生船船型试验研究

建造具有良好阻力性能及耐波性能的海上快速救生船是当务之急。作者通过试验,重点研究了两种新船型的技术关键问题。半潜体船型:变化了半潜体大小,纵向位置及浸深,试验表明它在一定速度范围内既能减阻,又能较大幅度改善纵向运动性能。小水线面船型:采用理论方法计算了它的纵向运动稳定性,并设计了3组鳍。试验测定了船模的运动纵倾力矩,为实船控制提供了依据。

Test and Research on the Ship Type of High Speed Life Boat at Sea

It is a pressing matter at the moment to develop a high speed life boat with good resistance and seakeeping performance for sea-going ships. The authors make emphasis on the research of the key technical problems of the following two boat types through test. Semi-submerged life boat: with different semi-submerged hull sizes, different longitudinal position and different depth of the submerged part. Tests show it not only reduces resistance but also improves the longitudinal movement performance considerablly. Small waterplane life boat: with its longitudinal movement stability calculated by theoretical method and three groups of fin designed. Trim moment of the moving boat was measured during the test, which provides a basis for the control of the boat.
