基于泛函数分析VPP计算模型的建立与实现

Establishing and Realizing of VPP Method Basing on Functional Analytic Theory

论述了泛函数分析的VPP计算模式及其实现过程．泛函数分析方法是一种VPP理论计算模型，文中比较巧妙地将帆与板的型值消掉，运用泛函数分析的方法建立了帆船、帆板VPP计算结果的简易校验标准．建立了水动力模型，假定板体阻力与船速的N次方呈正比（N分别为1，2，3），计算得到了8种风速、风向角25°～180°下的船速，为帆板逆风段航线选择提供了重要的依据。

The establishment and realization of a intact model of VPP calculating are discussed in the paper. Function analyzing method is a kind of the VPP calculating model which can eliminate the influence of the sail and board＇s size skillfully, so it can be regard as a brief standard of sailboard＇s VPP results. As a brief watery dynamical model, sailboard＇s resistance is supposed to be proportioned to the nth power of boat＇s velocity. The boat-velocities at the states of eight wind-velocities with angles of 25°～180° are obtained by calculating, which provides an important gist for the sailing-route＇s selection in upwind sailing.
