2、力特性，并比較了潛艇帶首舵和圍殼舵的升阻力特性差異，以及對(duì)艇體表面壓力分布和尾部流場(chǎng)的影響。計(jì)算結(jié)果顯示，相同舵角下，圍殼舵和首舵阻力相差不大，圍殼舵升力比首舵升力大。相同舵角下，潛艇總阻力相差不大，帶首舵潛艇總升力、總力矩比帶圍殼舵潛艇總升力、總力矩大。圍殼舵舵角的變化對(duì)艇體表面的壓力變化影響相對(duì)首舵來(lái)說(shuō)較小。圍殼舵和首舵在較大舵角下，都會(huì)對(duì)尾水平舵產(chǎn)生顯著影響。關(guān)鍵詞：圍殼舵；首舵；水動(dòng)力性能；Suboff；數(shù)值仿真中圖分類號(hào)：U661.1文獻(xiàn)標(biāo)識(shí)碼：A文章編號(hào)：1672–7649(2017)10–0022–07
