摘要
基于深V型滑行艇的系列模型阻力试验数据,比较系统地分析了深V型滑行艇静水阻力的影响因素,研究了阻力、浸湿面积、浸湿长度以及航行纵倾角随折角线长宽比、重心纵向位置、负荷系数、艇底斜升角等因素的变化规律,指出在舯部斜升角保持24.6°不变的前提下,艇底艉部横向斜升角为10°左右时滑行艇静水中的阻力性能较优,进一步增加增升角度对静水阻力性能不利。
The influence factors of resistance of Deep-V planing craft in still water were systematically analyzed in this paper, based on the experimental data. The variation of resistance, wetted surface area, wetted length and the trim of the planing craft, with respect to the changing of the factors, such as the ratio of the projected chine length to the maximum breadth over the chine, longitudinal center of the gravity, area coefficient, and deadrise angle of planing bottom, were also investigated. The resistance performance of this kind of craft in still water is found to be better, with about 10° deadrise angle at stem, on the condition of 24.6° deadrise angle at middle bottom.
