翼滑艇是江蘇科技大學(xué)提出來的一種新型高速船。它是綜合了滑行艇和水翼艇的性能而得到的一種新型復(fù)合船型，是以滑行艇的滑行面作為船體，而在首部安裝水翼。這樣水翼可以提供支撐船體的升力，有助于減小滑行艇的海浪拍擊、提高船體的穩(wěn)定性，同時在翼航狀態(tài)時，相比較水翼艇來說，部分船體在水下，其操縱性得到了改善。陳淑玲編*的《翼滑艇水動力特性研究》利用實驗和數(shù)值計算的方法對翼滑艇的水動力特性進(jìn)行了初步研究。內(nèi)容包括水翼艇及機翼理論、滑行艇水動力特性實驗研究、翼滑艇水動力特性實驗研究、高速船水動力特性數(shù)值研究實現(xiàn)、網(wǎng)格依賴性和計算域尺寸研究、滑行艇水動力特性在定常流動中的數(shù)值研究、翼滑艇水動力特性在定常流動中的數(shù)值研究、翼滑艇水動力特性在非定常流動中的數(shù)值研究等。
本書可供從事高速船水動力特性研究的科研人員和設(shè)計人員以及有關(guān)高等院校的教師和研究生參考。
