Besides, as it is very difficult in using Manning's equation to compute directly, traditional method made some approximation in application.

To be sure, we are behind, and will be behind for some time in manned flight.

很显然…我们落后了，并且在载人航天方面将继续落后一段时间。

The craft and the capsule are designed for manned flight, but there is no crew for this test.

飞船和太空舱为载人飞行而设计，但此次试验没有机组人员。

People generally credit the Wright brothers for having accomplished the first manned flight of an airplane.

人们多是歌颂莱特兄弟，是他们实现了飞机的第一次载人飞行。

The manned spacecraft and carrier rocket for the Shenzhou-12 manned space mission have arrived at the Jiuquan Satellite Launch Center in northwest China.

HISTORY Airborne launches date back decades, most famously to the X-15 program of the 1950s and' 60s, when manned rocket planes were carried aloft under the wing of a B-52 bomber and released on hypersonic research flights.

历史回顾机载发射可以追溯至几十年前，最著名的是上世纪50、60年代的X-15计划，当时一架B-52轰炸机的机翼下搭载了载人火箭飞机，并在超音速飞行的测试研究飞行器上发射。

The public showing was the first concrete evidence of progress since the Rutan-designed SpaceShipOne became the first private, manned rocket to reach space in2004.

本次（“白骑士2号”）的公开亮相成为自2004年鲁丹设计的“太空一号”成为第一艘进入太空的私营载人火箭之后（在太空旅游领域）取得的又一次具体进展。

Another potential advantage for UAS is that future designs may be better able to survive in contested airspace than manned aircraft are.

无人飞行系统的另一潜在优势是，其以后的设计会使其比载人飞行器更好地存活于竞争激烈的空域。

Applying shipborne UAV to radar jamming is the supplement for the manned aircraft and can increase jamming probability effectively.

应用无人机进行雷达干扰可以构成有人干扰机的重要补充，提高干扰效果。

So we can foresee that manned aircraft and unmanned aircraft appear together on the route will become normal.

所以，我们可以预见到在未来的天空里有人飞机与无人飞行器并存的情况将会成为常态。

Advocates of continuing investment in manned aircraft point out that current drones depend on two-way satellite communications.

支持继续在载人飞行器上投入资金的人指出，现有的无人飞信器依赖于双向卫星通讯系统。

Nothing comparable can be done with ground-supporting manned aircraft, he said.

他说到，地面支持的载人驾驶飞机简直无法相比。

But other experts say drones or manned aircraft will only have a limited impact.

但其他专家则认为无人机或载人飞机只会产生有限的影响。

Along with persistence, UAS have other potential advantages over manned aircraft.

除了耐久性，UAS较人工飞行器还有其他潜在优势。
