本发明的有益效果是：
本发明引前水推进船舶应用消波三原则及环流理论，采用转移兴波水源消除或消减 推进排水或及型体波系与射流干扰的方法。特别是当常规排水型船舶动力及推进装置能 引推等于同时推进段前水量时， 就不再产生船舶排水兴波及兴波对航行的干扰， 其结果 不但减免了推进兴波耗功、使航行不再涉及兴波及其峰值阻力， 而且引推全部前水产生 的巨大推力及激发的水动推进力让船舶航行随功率的发挥而进入高速或飞速状态。既使 在动力及推进装置容量不足于应对全部前水的条件下，选用引前水艏两侧推进结合流线 型型体等设置， 也能达到分水消波及射流干扰消波与消阻，增创水动推进力及改善推进 介质， 提高效率， 航速等综合性能的发明宗旨， 其事半功倍的效能为现有条件下打造高 性能常规排水型船创建了新的理论与技术基础， 并突显出本发明的如下具体有益效果。
1. 消波减阻降耗增效
因本发明引前水推进船舶可通过转移原推进时产生兴波的全部或部份船前水达到 完全消波或消减兴波，以及设置引前水艏两侧推进的高速射流干扰剩余兴波来消除兴波 阻力。扭转了常规排水型船航行耗功兴波并衡生有害的兴波阻力的不利状况， 从而避免 了航行应对兴波阻力峰值需付出的甚至无法容忍的功率代价，破解了长期以来常规排水 型船因兴波阻力与航速呈 6次方成正比及航速与功率的立方关系、而航速难以突破的物 理现象及费劳德数低数位徘徊的局面。引前水推进不但将产生兴波与兴波阻力的船前水 转化为有益推进的动力源，还可将排水兴波无效耗功调剂为有益的推进动力。给现有动 力与推进技术足以应对剩余阻力， 保障 了船舶具幅度的提速所需功率， 使常规排水型 船挤身高性能船列。 并给实现 1997 秋美国五角大楼讨论的航速达 100KN , 装载 2000-10000T, 航程 10000η mi le的船舶课题展现了阶梯。
2. 拥有一流介质提高推进系流工作效率
因引前水推进船舶的推进介质由船舶推进水平切入，且在流道内不发生或减少位移 而内阻小，所以切入引水较其它引水方式能降低功耗。而且进水速度或量由航速随机自 由调节， 并且因船舶推进重力及流道或槽道的挤压， 使推进装置的前级介质压力， 密度 均优于现有技术的螺旋浆工作于艉伴流或喷水推进耗功上引船底或侧引弦侧水。对消减 桨叶空泡与其引起的激振、 噪声及推力减额分数， 给加大推进器盘面比， 提高螺旋桨转 速或设置泵推进， 提高推进器工作效能， 延长推进器工作寿命创造了一流的介质因素， 使船舶动力及推进系统等综合效率都得以提高或创新。
3. 设置引前水艏两侧推进给应用流体动力学开发推进射流的动量动能兼备多种功 能。
引前水艏两侧推进的流道短， 管流阻力小。 如艏两侧设置管鼻式推进器， 制造成本 低， 性价比高。
引前水艏两侧推进结合两侧流线型型体设置，并配合艏前设置管鼻体下底上抬或及 两侧上跷， 流道的外凸， 艉螺旋桨推进及艉围鳍的设置， 使艏两侧推进的高速流自出水 口至艉尖延续形成高速高压环流， 使船体两侧速度场水位上升， 压力分布均衡。 高速高 压环流的动能合力作用于两侧流线型去流段。
a. 能激发产生使船前进的水动推进力。
b. 能抬升船体， 产生从高水头至低水头的下滑动力， 加上引前水推进正面阻力 小， 提高船舶逆水航行性能。
c 能干扰剩余兴波与消除艉波及伴流。
d. 能稳定边界层片流流态与边界层离体， 降低摩擦阻力。
e. 能阻挠海潮与涌浪， 避免漂流物的撞碰及偏转水面攻击物轨迹， 降低船体两 侧的水位与压力差， 减轻横摇增幅甚至共振。
f. 可配合设置侧铲戽或侧铲舵替代侧推进器， 减免重复装机。
g. 可利用二侧差速实现无舵操控， 消除舵阻力， 同时一改常规的摆艉操控为挥 艏操控， 有利于及时灵活地修正航行轨迹， 执行紧急规避海事。 h. 能成型前肩部最大横截面及船浮心前移， 给前机型与前楼设置提供了优选条 件， 并可降低船楼高度， 便于视察船前动态与操控。
i. 逆转了原船航行艏部兴波增压， 艉部推进压降， 似逆向航行的姿态。
j. 倒车反应快， 效能高。
4. 打破了目前高性能船列中小型化及低载荷， 高耗功率， 经济效率低， 适应水域 界限， 续航能力低的局面
引前水推进可消除兴波阻力，扭转了长期以来以加大船体长宽比与加大轴功率应对 兴波及其峰值阻力的常规做法，给打造高性能， 高强度大型甚至超临界巨型船舶或经济 型的短深型、 短肥型船舶提供了技术保障， 填补了大型或巨型船舶高性能的船史空白。
5. 解决了快速性与稳性的矛盾
引前水推进船舶可消除或消减兴波，使波系阻力得以消除或降低外， 也使航行波系 平稳。另外设置艏进水口与流道或水道能吸收及缓解浪潮对艏部的砰击， 反而提高了桨 叶的前级压力。船舶的大型化及艏前管鼻体及艉围鳍的设置能增大运动阻尼，提升了垂 向， 纵向与横向的稳定。船舶设置流道的结构质量与容积， 其中容积与外水通联而不增 加船舶负荷， 但具镇船作用， 并降低船舶重心，对提高稳性有利、尤其是轻载荷，抬升、 颠簸摇荡的动态得到扼制，减缓甚至消除。设置流层的结构使船船具多层底的结构功能， 有利于提高船舶的破损稳性与续航能力， 提高了船舶的快速、 稳定、 安全的综合性能。
6. 改变了原艏艉的结构功能
原为缓和兴波设置的长轴线尖锐艏的功能消逝， 相应延长平行中体或流线型体长 度， 有利于降低摩擦阻力。 原为压艉设置的悬艉的功能也同时消逝， 均有利于降低结构 成本， 提高载荷。
7. 创建了管鼻体引水与导航新技术
管鼻体除增大升沉阻尼外：
a. 能起到水下推进楔入导向。
b. 能产生附加波系。
c 能稳定艏部的吃水深度， 确保稳定引水。
d. 不扰动底水及侧水入口。
e. 能建制一个提前量
f. 平缓艏侧下部排水进角。
g. 底部抬升及两翼上跷能起到深部排水与高速时的水翼作用。
8. 派生发明了宜设置于船底部及两侧部的管道式推进器及管鼻式推进器， 该两种 推进器集进出水口与推进装置于一体而内阻小， 还能设置成宜艏艉双向推进船 舶配备的推进器。 其前后向设置及切入引水使动力及推进器效率得到提高或创 新。
9. 维护推进器工作正常
引前水推进船舶的推进装置可设置于出水口或管道内， 可不受边界层， 涡流或伴流 的干扰， 也不会引起船体偏侧。进水口可设置排污栅控制推进介质质量， 有效地保护流 道及推进装置的安全。 并且推进装置的安装、 调试、 保养维修均于体内进行， 工作环境 得到改善， 既安全又方便。
10.能适用现有船舶改造并提升现有技术效率。 如配合现有艉推进船舶设置艏两侧管鼻式推进器，也能干扰消除兴波阻力与消减摩 擦阻力， 并改善艉部介质状况， 实现无舵操控， 配备侧铲戽或侧铲舵就能使船舶具备侧 推进功能， 而且现有船舶改造工费低， 适应性广。 又如现有艉推进的邮轮可配合设置艏 两侧明轮式推进器推进， 明轮式推进器具有的搅拌器及滤波功能， 也能实现艏两侧推进 的功能与效率， 并能体现古典文明与现代船舶技术溶为一体的价值观。
