带阻流板和水平翼的高速深V复合艇新构型研究

高性能复合艇通常比常规高性能艇具有更好的航行性能，本文以某高速深V型快艇为研究对象，采用阻流板和水平翼组合附体的方式对该深V复合艇进行CFD水动力性能数值模拟，对过渡状态及滑行状态下该复合快艇的阻力性能以及航行姿态进行评估，结合自由面兴波以及艇体表面压力分布情况，最终获得了一型深V复合艇构型设计方案，该复合艇运动姿态得到大幅改善，过渡状态下模型总阻力值较原型减少18.97%。

Study on new configuration of high speed deep V composite boat with interceptor and horizontal fin

High-performance composite boat usually have better navigation performance than conventional high-performance boat.In this paper, we take a high speed deep V boat as the research object,and carry out the CFD hydrodynamic performance numerical simulation for the deep V composite boat with using the method of the combined appendage of interceptor and horizontal fin, and evaluate the resistance performance and sailing posture of the composite boat in the state of transition and glide,combined with free surface wave and surface pressure distribution.finally, the design scheme of a deep V composite boat configuration is obtained.The composite boat sport posture has been greatly improved,under the transition state, the total resistance of the model is reduced by 18.97% compared with the prototype.
