摘　　要：采用滑行艇阻力估算Savitsky法,对平底滑行艇进行航态计算、阻力估算及航速预测,并与试验结果对比,验证阻力估算方法在总体设计阶段的适用性。通过改变艇体重心位置与长宽比,计算相同推力及排水量下的阻力曲线,研究各因素对阻力估算的影响。The Savitsky method is used to calculate the state,resistance and speed of the flat bottom planning hull.The applicability of the method in the overall design is verified by comparing with the test results.By changing the CG position and the aspect ratio,the drag curve under the same thrust and displacement is calculated,and the influence of various factors on the resistance estimation is studied.
