音速的

But very quickly after that, I have to bring the throttles out of AB to make sure I'm not supersonic by the time I get to the show center again.

但是很快，我就要把油门从加力状态下收回以保证我在飞过展览中心上空的时候不会超过音速。

In the background of numerical simulation for the transonic flow about advanced transport aircraft with wing-mounted nacelles, great efforts have been made in this thesis for the improvement of the grid generation technique and the numerical methods for solving the Euler equations.

本文以民用飞机复杂外形跨音速绕流数值模拟及气动力分析为应用背景，在复杂空气动力外形网格生成技术，Euler方程数值求解方法的改进。。。

Hypersonic aircraft to fly faster secret lies in its use of a ram-jet engine.

高超音速飞机飞得快的奥秘在于其采用了冲压式喷气发动机。

OVAL Co., Ltd.

生产符合GB/T2624--936和ISO5167--1的标准节流装置；包括角接取压标准孔板、标准喷嘴、法兰取压标准孔板、径距取压标准孔板、长径喷嘴以及文丘里管和文丘里喷嘴、双重孔板、偏心孔板、圆缺孔板、锥形入口孔板、端头孔板、皮托文丘里管、音速喷嘴等。

A whip makes a cracking sound because its tip moves faster than the speed of sound(760 miles per hour).

鞭子能发出劈啪声，是因为鞭端运动的速度比音速（每小时760英里）快。

This paper presents design and experimental resultsfor a high performance single stage transonic fan with design pressureratio 2.3 and design efficiency 0.88 at high tip speed 510m/s (relativeMach number reaches 1.72) and low aspect ratio.

本文介绍一高性能单级跨音速风扇的设计与试验结果。该风扇设计压比2.3，设计效率0.88，具有高切线速度510 m/s(相对马赫数达1.72)和低展弦比。

Prior to this, the world's fastest jet flight record of 3.2 times the speed of sound, from the U.S. Air Force SR-71 "Blackbird" high-speed high-altitude strategic reconnaissance plane to create.

此前，世界上喷气式飞机的最快飞行纪录为3.2倍音速，由美国空军SR-71&黑鸟&型高空高速战略侦察机创造。

For decades, researchers have dreamed of building hypersonic aircraft that could whip around the world in just a few hours.

几十年来，研究人员一直梦想着制造出在几个小时内就能绕地球飞行一圈的超高音速飞行器。

The missile uses active radar homing and is powered by a turbojet. The anti-ship missile has a range of 120km and approaches the target in sea skimming mode at a speed of 0.9 Mach. The 165kg shaped charge warhead has time delayed impact proximity fuses.

导弹使用主动雷达制导，由涡喷发动机推进（还有一个固体火箭助推器），射程120千米，在掠海模式下攻击速度0.9倍音速。165千克的成型装药战斗部装有延时触发引信。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
