摘 要
高速無(wú)人滑行艇具有高速、隱身、智能等優(yōu)點(diǎn)，因而能夠用于靈活作戰(zhàn)，目前，國(guó)外已有多種水面高速無(wú)人艇應(yīng)用于軍事領(lǐng)域，特別是以美國(guó)為代表的西方國(guó)家已將其列為重要的發(fā)展方向；國(guó)內(nèi)在水面高速無(wú)人艇技術(shù)方面的研究還處在初級(jí)階段，近年來(lái)研制出的無(wú)人駕駛船也只是應(yīng)用于探測(cè)天氣，為了更好低完善我國(guó)海軍作戰(zhàn)體系，帶動(dòng)相關(guān)軍工業(yè)的發(fā)展。
本文進(jìn)行的主要工作有：
一、 針對(duì)目前國(guó)內(nèi)外的高速無(wú)人艇研究發(fā)展現(xiàn)狀展開了調(diào)查研究，并對(duì)我國(guó)目前滑行艇阻力、穩(wěn)性、耐波性和新艇型的開發(fā)進(jìn)行簡(jiǎn)單的介紹。
二、 從任務(wù)需求出發(fā)，結(jié)合現(xiàn)有條件，利用Maxsurf軟件進(jìn)行單體滑行艇模型的設(shè)計(jì)，并對(duì)模型進(jìn)行了流體性能的初步計(jì)算分析。
三、 進(jìn)行了推進(jìn)器的設(shè)計(jì)，并對(duì)噴水推進(jìn)器的種種要素對(duì)各個(gè)性能的影響進(jìn)行了分析。
四、 以滑行艇前進(jìn)、升沉及縱搖運(yùn)動(dòng)為目標(biāo)開展滑行艇流體性能的初步分析。
五、 建立了船前進(jìn)、升沉、縱搖三自由度運(yùn)動(dòng)數(shù)學(xué)模型，開展了滑行艇三自由度運(yùn)動(dòng)預(yù)報(bào)，分析了高速滑行艇運(yùn)動(dòng)特點(diǎn)。

Abstract
Unmanned Surface Vehicle (USV) has some good properties such as high-speed, stealth, intelligence, etc, which can be used for flexible operations, currently, there are many foreign high-speed unmanned surface vessels in the military field, especially the United States as the representative of the Western countries have their as an important direction of development; domestic high-speed unmanned craft on the water technology research is still at the initial stage, developed in recent years of unmanned boat only apply detect the weather, in order to better improve our naval combat system of low, promote the development of military-industrial related.
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 of three degrees of freedom movement; report Exercise of crafts.
