船舶与海洋工程专业毕业论文专业高速无人艇设计与运动性能初步分析摘要高速无人滑行艇具有高速、隐身、智能等优点，因而能够用于灵活作战，目前，国外已有多种水面高速无人艇应用于军事领域，特别是以美国为代表的西已将其列为重要的发展向；国在水面高速无人艇技术面的研究还处在初级阶段，近年来研制出的无人驾驶船也只是应用于探测天气，为了更好低完善我国海军作战体系，带动相关军工业的发展。
本文进行的主要工作有：一、针对目前国外的高速无人艇研究发展现状展开了调查研究，并对我国目前滑行艇阻力、稳性、耐波性和新艇型的开发进行简单的介绍。
二、从任务需求出发，结合现有条件，利用Maxsurf软件进行单体滑行艇模型的设计，并对模型进行了流体性能的初步计算分析。
三、进行了推进器的设计，并对喷水推进器的种种要素对各个性能的影响进行了分析。
四、以滑行艇前进、升沉及纵摇运动为目标开展滑行艇流体性能的初步分析。
五、建立了船前进、升沉、纵摇三自由度运动数学模型，开展了滑行艇三自由度运动预报，分析了高速滑行艇运动特点。

This major work carried out are:First，A view of the current domestic and foreign research and development of high-speed unmanned craft launched a survey on the current situation, and introduce resistance, stability, seakeeping, and the development of new hull of our country current planing boat.Second, from the mission requirements, combined with existing conditions, use of Maxsurf single planing hull model of software design, and model the performance of the preliminary calculation of fluid analysis.Third, for the propeller design, and all the elements of water jet propulsion of individual performance was analyzed.Fourth, in order to slide the boat forward, heave and pitch motion targeting of planing craft a preliminary analysis of fluid properties.Fifth, the establishment of the boat forward, heave, pitch three degrees of freedom mathematical model, carried out three-DOF motion planing prediction of high-speed planing craft motor.Keywords: unmanned planing crafts; Performance Analysis; numeral model ofthreedegrees of freedom movement; report Exercise of crafts.目录第1章绪论 (1)1.1引言 .......................................................................................................................... 1 1.2课题背景 ..
