The invention discloses a high-speed boat linetype combining a low-resistance drainage boat bow and a deep V-shaped planing boat stern, the linetype combines the characteristics of a long and sharp bow, a composite bottom rising line, a gradually-changed deep V-shaped planing boat type and the like, and the high-speed boat linetype is low in drainage sailing resistance, small in slapping force borne by a boat body during sliding, low in friction resistance and good in rapidity, seakeeping and navigability. A composite wave suppression structure composed of oval arc lines is adopted for the bilge part, by means of the bifocus reflection characteristic of an oval, transverse water flow rushes into the oval arc face from one focus F2 and is reflected to the other focus F1, part of splashing energy is converted into useful lifting force, and the dual purposes of saving energy and reducing splashing are achieved. Comparison experiments show that in tests of combination schemes of different navigational speeds and voyages, the fuel consumption of the embodiment is greatly reduced compared with that of a contrast boat. The method is simple and easy to implement, the energy-saving effect is obvious, and good social and economic benefits can be achieved after popularization.

    本发明公开了一种将低阻力排水艇艏部与深V滑行艇艉部组合的高速艇线型,这种线型将长尖艏、复合底升线和渐变深V滑行艇型等特征结合起来,其排水航行阻力低,滑行时船体所受拍击力小、摩擦阻力低,具有良好的快速性、耐波性和适航性。其舭部采用由椭圆弧线构成的复合压浪结构,利用椭圆的双焦点反射特性,使横向水流从一个焦点F2冲入椭圆弧面,并反射至另一个焦点F1,将飞溅的部分能量转换为有用的升举力,实现了节能和减小飞溅的双重目标。对比实验表明,在不同航速与航程的组合方案试验中,实施例的燃油消耗比对照艇大幅度降低。本发明简单易行,节能效果明显,推广后可实现良好的社会和经济效益。
