Adaptive α-β filter algorithm was introduced, and then it was compared to ISR filter algorithm and Kalman filter algorithm, the mean square deviation of distance, position, speed and direction of these algorithms on the flight line was analyzed to discuss the specific use of the three filters in straight-line flight and about-ship straight-line flight.

介绍了一种改进的α-β滤波算法，然后将它和最小二乘滤波算法、卡尔曼滤波算法进行比较，对三种算法跟踪空中目标的直线飞行、改变航向的直线飞行两种情况的距离、方位、速度和航向等参数的均方差加以分析，证明了改进的。

Yet aviation history is littered with the wrecks of unmanned-aircraft projects—some of them barmy, others simply too far ahead of their time—that were given a variety of names, including "aerial torpedo" and "remotely piloted vehicle".

然而，航空的历史却到处充塞着无人驾驶飞机项目的残骸——有些比较胡闹，而有些则太过于超前——当时这个飞行机有很多的名字，包括"天空鱼雷"与"远程驾驶飞行机"。

The aerobatics of insects are truly amazing, but what enables these creatures to excel in flight beyond any human flying machines?

昆虫的飞行特技确实令人赞叹不已。可是这些昆虫在飞行方面是怎样胜过人类的飞行器的呢？

As well as serving as a military training aircraft, the Yak-152K will also be suitable for primary training and aerobatics in flying schools and clubs.

除了服役当作一种军用教练机，雅可-152K也将会是适用于飞行训练学校和俱乐部的主要训练和特技飞行。

It is extremely important for the popularization of cyber air sports to let more people see the online air combat and aerobatics perform and more fresh men learn the skills of flying and fighting easier.

使更多人能在线观看空战和特技飞行表演，使更多新人更容易学习飞行和空战技巧，对于这项运动的普及是非常非常重要的。

For VFR flights, the time at which it is estimated that the aircraft will arrive over the aerodrome.

对于以目视飞行规则飞行的飞机，是飞机将到达机场上空的估计时间。

Aerodyne will reach good flying performance both in fast flight and in hover.

aerodyne将达到良好的飞行性能都在快速飞行，并在悬停。

TILT ROTORCRAFT : An aerodyne which derives the whole or a substantial part of its lift for vertical or hovering flight by tilting rotor upward to a position substantially vertical, and in forward flight derives its lift from rotors and/or wings, and is capable of autorotation in the event of power failure.

倾斜旋翼飞机：一种旋翼机，垂直或悬浮飞行时，整个或其中相当一部分之爬升力源自倾斜旋转翼使上升到一个极度垂直的位置，而在向前飞行时，爬升力源自旋转翼和/或机翼，并有能力在发生动力供应中断时自动旋转。

This paper discusses the theory method calculating surface temperature of ballistic target above aerosphere, and analyses the effect of dimensional orientation of target s flight gesture and sun radiation direction on its surface temperature.

论述了大气层外弹道式目标表面温度的计算方法，对某弹道式目标大气层外飞行过程中当太阳辐射方向改变时其表面温度的变化情况进行了数值计算，分析了目标飞行姿态与太阳辐射方向之间空间方位关系的变化对目标表面温度的影响。

We had requested a flight following plan from Air Traffic Control, and it had been in operation.

我们刚才向飞行控制中心要求了我们的飞行航线，而且我们都一直跟著他们的指示。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
