飞行器

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。

More than 200 people have been killed worldwide as a result of wildlife strikes with aircraft since 1988, according to Bird Strike Committee USA, and more than 5,000 bird strikes were reported by the U.S.

据美国飞鸟撞击协会提供的数据显示，自从1988年以来，全球由于野生动物与飞行器相撞已导致超过200人遇难，另据美国空军的报道仅2007年一年里就发生了超过5000次的飞鸟撞击事件。

Jet-packing hordes could transform the skies into an aerial demolition derby, with air rage and drunk drivers turned into wobbly human torpedoes.

一帮帮的飞行器会把天空变为拆楼大比拼；那些&空中暴怒&、酒醉飞行员会变成了一条条不稳定鱼雷。

They appeared to be flying at an altitude of about 3,500 meters (11,480 feet), and allegedly surrounded the Air Force jet as it conducted routine anti-drug trafficking vigilance in Campeche. Only three of the objects showed up on the plane's radar.

他们当时似乎飞行在3500米（11，480英尺）的高度，并且据称一度还包围了这架正在坎佩切州执行例行的反贩毒走私警戒任务空军飞行器，但只有飞机的雷达上只显示了其中的三个物体。

A calibration target,made up of double feature circle of co-plane,was attached on the airplane′s rudder.

用共面的两个特征圆组成一标定靶固定在飞行器舵面上，用一台定焦数码摄像机对标定靶拍照，获得特征圆数字图像。

Both craft tumbled, lost fifty meters of altitude, and then recovered—but their leading edges scraped the ground, dissipating their weakened shields, and they spun end over end erupting into fiery pinwheels.

两架飞行器翻着斤斗，下降了五十米的高度，然后又恢复原来的姿态——但是它们的翼边擦到地面，使他们那本已变弱的护盾消失，它们翻滚着从尾端爆成炽热的旋转焰火。

A method to calculating maneuver for special point maneuver strategy is developed based on the facts that are single objective of every maneuver and tiny correction for orbit inclination and right ascension of ascending node. The basic idea of the method is disassembling calculating for phasing and orbit plane correction, and the equation for calculating maneuver is derived.(2) A method for determining the optimal collision avoidance maneuver is developed, and the two phasing orbits strategy is developed to avoid collision with debris.

1研究了远距离导引的特殊点变轨策略，针对特殊点变轨策略每次机动目标单一和轨道面修正为小量的特点，提出了将轨道面内调相与轨道面修正分解计算的策略，推导了采用高精度轨道模型的调相和轨道面修正机动计算公式；(2)研究了远距离导引段飞行器规避空间碎片的机动问题，提出了一种双调相轨道机动策略，并给出了碰撞规避机动的计算公式。

Estimation of the aero-thermodynamic parameters of reentry vehicle is a typical application of DPS identification in the aeronautical and astronautical research fields.

对再入飞行器的气动热参数辨识进行了研究。

Techniques of aerocraft environmental control,aeronautical and astronautical working

环境工程学科的基本思想，研究内容和研究方法，特别介绍飞行器环境控制技术

We found we didn't need a flexible trailing edge concept, although this was one of the AFRL ideas for SensorCraft.

我们发现不需要可变形机翼后缘概念，尽管那是AFRL的传感飞行器设计概念之一。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
