摘　　要：根据滑行艇Froud数高、排水量小的特点，采用约束模旋臂试验加操纵性预报方法研究该艇操纵特性。考虑到该艇回转时具有较大的横倾；本艇操纵性预报的数学模型，采用纵向、横向、回转和横摇的4个运动方程，其中船体水动力采用该艇模型旋臂试验结果。文中给出了6种工况下回转及Z形机动的计算结果，并由此综合评价该艇操纵性能。Acoording to the property of high Frond number and low displacement, a combination of captive model test and calculation prediction method is used to determine the maneuverability of the planing craft. Considering the large rolling angle during the turning of this craft, the four equations, longitudinal, lateral, turning and rolling motions are used for the maneuverability prediction of this planing craft. Hydrodynamic forces of foe hull are given by the rotating arm model tests. Ln this paper, the calculating results which is used to evaluate the maneuverability of this craft, are shown with six conditions.
