adj.比音速稍慢的；次音速的

I have no idea what subsonic speed is. 我實在不明白什么是亞聲速。

Nonlinear Aeroelastic Analysis of Complete Aircraft in Subsonic Flow. 亞音速流中全飛機(jī)的非線性氣動彈性力學(xué)分析。

This airplane can go out to high subsonic speeds very easily without using afterburner. 這架飛機(jī)能夠很輕松地在不打開加力的狀態(tài)下飛到高亞音速。

This paper presents a ALGOL program for Calculating The lift distribution on wings with control surface in steady and unsteady subsonic flow. 本文提供了計算亞音速偏轉(zhuǎn)操縱面機(jī)翼的定常和非定常升力分布的算法語言程序。

When the Switchblade returns to subsonic speeds, the wing will rotate back to perpendicular. 當(dāng)這種“轉(zhuǎn)向翼飛機(jī)”恢復(fù)亞音速飛行時，機(jī)翼就轉(zhuǎn)回垂于直機(jī)身的角度。
