芬兰气垫巡逻艇T-2000设计特点与总体性能分析

Design features and overall performance analysis of Finnish air cushion patrol boat T-2000

芬兰气垫巡逻艇T-2000是近期设计建造的一型全垫升气垫船,用于岛屿间的快速巡逻。其采用CDIM-SDD的第二代深型响应围裙系统、全新构型的首部矢量喷管,具有突出的快速性、操纵性及航行安全性,海试中创造了超过70 kn的气垫船最高航速,在众多岛屿之间操纵灵活便捷。为满足隐身要求,除采用低构型首部矢量喷管外,还采用多角形内倾复合材料上层建筑、低速大直径垫升风机与导管空气螺旋桨、风机全部顶部进气、主机冲压进气与水平向后直排出气等多项新技术。T-2000优良的总体性能以及新颖的设计理念和先进技术,值得国内设计人员学习与借鉴。

The Finnish air cushion patrol boat T-2000 is a recently designed and built full air cushion craft used for the fast patrol between islands. The second-generation deep responsive skirt of CDIM-SDD and bow vector nozzle with new configuration have been adopted on it. It has outstanding power performance, maneuverability and navigation safety. Its speed during the trail test was above 70 kn, which is the highest speed of the air cushion vehicles. It also can be manoeuvred flexibly and convenient among islands. To meet the stealthy requirement, many new technologies are adopted besides of the bow vector nozzle with low configuration, such as polygon inward inclining superstructure made by composite materials, low-speed lift fan and ducted air screw with large- diameter, entire top intake fan and main engine with ram air inlet and horizontal backward exhaust air outlet. The great overall performance, the novel design concept and the advanced technologies of the T-2000 can be referenced for the designers at home.
