Pitch-yaw coupling can be neglected only for nearly axisymmetric vehicles . 只有對(duì)接近于軸對(duì)稱的飛行器,俯仰與偏航的耦合才能略去。
In addition to a longer nose , aerodynamic modifications feature kfir - style small nose side - strakes to prevent yaw departure at high aoa , a pair of fixed delta canards on the upper parts of the air intakes , dog - tooth outboard leading - edge extensions , and short fences replacing leading - edge slots 除了一個(gè)加長(zhǎng)的機(jī)鼻外,氣動(dòng)布局的修改包括:在機(jī)鼻兩則裝上可以防止在高攻角下脫離偏航的“幼獅”式小邊條,一對(duì)固定在進(jìn)氣道的三角鴨翼,鋸齒型外翼前緣,和代替前緣翼槽的短翼刀。
