摘　　要：为保障水上飞机起飞安全,研究起飞过程中的水上飞机与船舶的碰撞危险度。基于水上飞机与船舶的运动特点和安全需求,在已有船舶领域研究的基础上,将水上飞机滑行阶段和爬升结合起来,构建水上飞机三维动态领域;引入动界概念,根据目标船与水上飞机领域、动界的位置关系,建立滑行阶段水上飞机与船舶的碰撞危险度模型;综合考虑水上飞机与船舶在水平方向和垂直方向的碰撞危险,建立爬升阶段水上飞机与船舶的碰撞危险度模型。以湛江某水上机场为例进行验证,结果表明,该模型可有效确定水上飞机起飞过程中与船舶的碰撞危险。采用三维动态领域计算水上飞机与船舶的碰撞危险度,既涵盖了滑行过程,又涵盖了爬升过程,具有较好的完整性,可为水上飞机起飞避碰决策提供参考。To ensure take-off safety of seaplanes,the collision risk indices between seaplanes during taking-off and ships is studied.Based on movement characteristics and safety requirements of both seaplanes and ships,a three-dimensional dynamic domain of seaplane is constructed on the basis of ship domain.A concept of Arenas is introduced,and a model of collision risk indices between seaplanes and ships in sliding stage is established according to the position relationships between domain and Arenas of seaplanes and ships.The collision risk between seaplanes and ships are comprehensively considered in the horizontal direction and the vertical direction,a model of collision risk indices of seaplanes and ships in climbing stage is established.Taking a Water Aerodrome in Zhanjiang as a case study for verification,the results show that the model can effectively determine the collision risk indices between seaplanes and ships during taking-off.It covers both the sliding stage and the climbing stage by using the three-dimensional dynamic field to calculate the collision risk indices between seaplanes and ships,which has good integrity,and can provide a basis for seaplane taking-off and collision avoidance decisions.
