外军两栖车辆水上推进装置的分类及评价

给出了当今外军典型两栖车辆的主要性能指标,对水上推进装置进行了分类,定性分析了各种水上推进装置的工作原理及主要影响因素,给出了FT-C牵引车模型的试验结果.通过对水上推进装置产生的推力和两栖车辆水上行驶的阻力分析,得出了有价值的结论.最后根据实际需求对履带划水式、喷水式、螺旋桨式3种水上推进装置进行了综合评估,其结论对新型两栖车辆的论证、研究具有借鉴作用.

Classification and Assessment for Water Propulsion Unit of Amphibious Vehicle in Foreign Army

This paper introduces the main performance indexes of the typical amphibious vehicle in foreign army nowadays, classifies the propulsion units used in water, makes qualitative analysis on operating principle and the main influential factors of the water propulsion unit, and also gives the experimental result of the GT-C tractor model. A full valuable conclusion is drawn from the calculation of the thrust caused by the water propulsion unit and the resistance occurred when am- phibious vehicles run in water Finally, according to the actual demands, an integrated assessment is made for the three kinds of water propulsion units:tracked propulsion, water jet propulsion and propeller The conclusion is useful for demonstration and research for new amphibious vehicles.
