两条大型全垫升气垫船的流体动力性能比较

Comparison of hydrodynamic characteristics of two large air-cushion vehicles

]以运输效率为基本判据 ,根据对无因次阻力、无因次推进功率与垫升功率的研判 ,从方案设计的角度分析了英国 SRN4 - MK3和俄罗斯 ZUBR(“欧洲野牛”)两条大型全垫升气垫船总体性能差异的原因 。

With the operation efficiency as the basic criterion and according to the judgment of dimensionless resistance, dimensionless propulsion efficiency and air-cushion power, the paper analyzes the reasons of overall functional difference between two large air-cushion vehicles—the British SRN4-MK3 and Russian ZUBR (“Euro Cattle”) based on their conceptual design. The article serves also an criterion for analysing design parameters for large air-cushion vehicles.
