A particularly investigation is carried out to the observibility of in-flight alignment using numerical simulation when the aircraft performs four kinds of basic maneuvre, namely linear acceleration, yawing, pitching and rolling. The thesis summarizes the two kinds of maneuvre. Simulation results show that the precision of transform alignment reach 5 minutes in 10 seconds if the aircraft performs two well-defined maneuvres.

首先本文采用数值分析的方法研究了直线运动、航向角运动、俯仰角运动和横滚角运动对传递对准系统可观性的影响规律；再结合飞机的实际运动，给出了空空导弹传递对准时的飞机飞行轨迹；"蛇形"飞行轨迹和摇摆运动飞行轨迹，仿真结果表明：按这两条飞行轨迹机动，在10s内传递对准精度可达到5′以下。

The shadow of photographer George Steinmetz's plane glides along Kenya's section of Lake Natron, where microorganisms living on the water's salty crust create a palate of pink.

摄影师乔治·斯坦梅茨乘坐的飞机掠过肯尼亚的纳特龙湖上空，飞机的影子投射在湖面由微生物形成的粉红色盐壳上。

"Yesterday it was a dream. Today it is a plane. Tomorrow it will be an ambassador of renewable energy," Piccard, the plane's creator and pilot, said at a news conference at Duebendorf airfield near Zurich today.

飞机的发明者及飞行员皮卡尔德今天在苏黎士附近的杜本多夫机场举行的新闻发布会上说：昨天，那是梦想，今天那是一架飞机，明天它将成为再生能源的大使。

French investigators announced Saturday that the plane had been scheduled to have its Pitot tube replaced, but it remained unclear whether the part had malfunctioned or had anything to do with the crash.

法国调查员声明道就在出事前的周六，本来根据安排要将这架飞机的空速管换掉。但是现在还不明确是否空速管的延迟更换造成了飞机的故障或跟这次坠机有任何联系。

The problem about high bullets shoot aeroplanes is a very important realitic problem of military affairs .This essay ,using intellectual of probability ,inquires into how to dipose firepower when we use high bullets to shoot aeroplanes ,and gets two major interesting conclusions.First, we should use firepower equally when the percentage of hits of each bullet is the same.

摘要高射炮打飞机的问题是军事上的1个很重要的实际问题，本文作者利用概率统计知识对用高射炮打飞机时如何进行火力部署做1些探讨，并得到了两个主要结果：（1）各们炮的命中率相同时，应平均使用火力。

A technician straps legendary test pilot Scott Crossfield into the cockpit of the X-15 rocket plane before an early test flight. The X-15's maiden flight occurred on June 8, 1959,during which Crossfield was carried aloft in his sleek, black rocket plane beneath the wing of a B-52 from NASA's Flight Research Center.

在一次早期试飞中，一名技术专家用飞行皮带把传奇的试飞员斯科特克罗斯菲尔德固定在X-15火箭推进式飞机的小驾驶室中。1959.6.8，X-15进行了处女航，它挂在一架B-52超级空中堡垒的机翼下从NASA德莱登飞行研究中心起飞，克罗斯菲尔德驾驶着黑色光滑的火箭推进式飞机完成了处女航。

Many people failed to design the flyable plane because they give up before the the last paper of blueprints of the plane has been finished.

许多人设计的飞机没能起飞的原因是他设计图纸的重量快要等于飞机的重量时，他先飞了。

Many people fail to design a flyable plane because he/her gives up when his/her blueprint nearly equals to the plane in weight.

许多人设计的飞机没能起飞的原因是他设计图纸的重量快要等于飞机的重量时，他先飞了。

But a group of researchers at StanfordUniversity, led by Ilan Kroo, has suggested that airlines could take a more naturalistic approach to cutting jet-fuel use, and it would not require them to buy new aircraft.

但在斯坦福大学，由伊兰克鲁领导的一个研究小组提出，飞机的飞行路线可以改用更具仿生效应的路径来节省燃油，而且并不需要购买新的飞机。
