亚音速飞机

This airplane can go out to high subsonic speeds very easily without using afterburner.

这架飞机能够很轻松地在不打开加力的状态下飞到高亚音速。

The results show tha,t at a subsonic speed, airplane turbulence increaseswith an increase in flying speed, and that a smaller airplane is affected more fiercely than a bigger one under the same air turbulence and weather condition.

研究表明，在亚音速下，飞机飞行速度增大，飞机颠簸增强；在同样的气象条件和大气湍流强度下，小型飞机的颠簸比大型机剧烈。

But it is unlikely that the shape of subsonic aircraft will change radically in the foreseeable future.

但在可预见的未来，亚音速飞机的形状不会发生根本的改变。

And then level it. But aircraft that excel at subsonic flight are inefficient at Mach speeds, and vice versa.

然而善于亚音速飞行的飞机，在进行超音速飞行的时候效果是不理想的，反之亦然。

The Shafaq is a subsonic aircraft with an empty weight of around 5,000 kg, an overall length of about 14 m and a 12 m wingspan.

Shafaq是一种亚音速飞机具有一个5，000公斤左右的空重，全长大约14米和翼展12米。

The objectives are the subsonic and supersonic zero-lift drag coefficients, the maximum lift-drag ratio, the maximum lift coefficient at low speed, the average and maximum value of forward and sideway RCS.

目标函数取为亚音速及超音速时的零升阻力系数、最大升阻比，低速时的最大升力系数，以及飞机前向、侧向的RCS平均值、最大值。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
