摘　　要：长宽比ＬＰ／ＢＰＸ是影响滑行艇静水阻力的重要参数．根据斜升角为１２．５°的ＤＴＭＢ－６２滑行艇系列阻力试验结果，分析了长宽比对阻力的影响．这种影响除与体积付汝德数ＦΔ密切相关外，还与其他参数，诸如静浮时的排水量及重心纵向位置等有关．同时给出了根据６２系列资料所得的最佳长宽比曲线．这些图谱可供实际滑行艇设计应用。To offer the basis for the selection in the design of planing hulls, based on resistance tests of a series of planing hull forms with 12.5° deadrise angle(the DTMB series 62) the influence of length beam ratio on resistance of planing hull forms was analyzed. The length beam ratio L P/ B PX is an important parameter affecting the calm water resistance of planing hulls. The effects depend on the volume Froude number F Δ as well as the other parameters, such as the displacement at rest and longitudinal center of gravity location. The optimal curves of length beam ratio obtained from the data of series 62 were given. Those charts could be used to get satisfactory performance for the design of actual planing hulls.
