1、船舶與海洋工程專業(yè)畢業(yè)論文專業(yè)高速無人艇設(shè)計(jì)與運(yùn)動性能初步分析摘要高速無人滑行艇具有高速、隱身、智能等優(yōu)點(diǎn)，因而能夠用于靈活作戰(zhàn)，目前，國外已有多種水面高速無人艇應(yīng)用于軍事領(lǐng)域，特別是以美國為代表的西方國家已將其列為重要的發(fā)展方向；國內(nèi)在水面高速無人艇技術(shù)方面的研究還處在初級階段，近年來研制出的無人駕駛船也只是應(yīng)用于探測天氣，為了更好低完善我國海軍作戰(zhàn)體系，帶動相關(guān)軍工業(yè)的發(fā)展。本文進(jìn)行的主要工作有：一、針對目前國內(nèi)外的高速無人艇研究發(fā)

2、展現(xiàn)狀展開了調(diào)查研究，并對我國目前滑行艇阻力、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)，并對噴水推進(jìn)器的種種要素對各個(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)動數(shù)學(xué)模型，開展了滑行艇三自由度運(yùn)動預(yù)報(bào)，分析了高
