飞行器

Therefore, a Chinese kite hangs in the American Washington Astronavigation Museum hall, writing "The human earliest flight vehicle is Chinese kite and the rocket." on it.

因此，在美国华盛顿宇航博物馆的大厅里挂着一只中国风筝，在它边上写着：&人类最早的飞行器是中国的风筝和火箭。&

The image quality is evaluated by the Modulation Transform Function,and the scopes of scroll angle and pitch angle that can meet the requirements of the space camera image quality are determined.

应用调制传递函数作为图像质量的评价依据，确定了满足空间相机成像质量要求的侧摆角和前后摆角范围，分析了飞行器侧摆和前后摆对地面像元分辨力的影响。

The normal angle of attack and bank angle were corrected according to the aerodynamic coefficient errors between the estimated values and the normal ones.

研究了气动模型存在误差情况下高超声速再入机动飞行器的制导律设计问题。

Firstly, the control of reentry phase and the model of RCS jets are presented. Then the flight control system is divided into two subsystems based on the time-scale separation principle. The fast states subsystem corresponds to the three body-axis angular rates, the slow states subsystem controls the angle-of-attack, sideslip angle and the rate of the bank angle about the velocity vector. Lastly, the proportional-plus-integral feedback is designed to increase the system robustness.

首先，分析了SRLV再入段的数学模型，并给出了反作用推力控制系统的控制模型；其次，将非线性动态逆方法与时标分离原则相结合，考虑飞行器姿态控制系统的外环角回路的慢变特性和内环角速度回路的快变特性，独立设计了两个回路的控制律；最后，为了增强系统的鲁棒性，分别在两个回路中引入了比例－积分反馈，有效地抑制了干扰力、力矩和非线性对消带来的逆误差。

VTOL aircraft is an under-actuated system with three degrees of freedom and two control inputs.

引言1VTOL空间飞行器是能够垂直起飞、垂直着陆的具有三个自由度，两个控制输入的欠驱动系统。

Apollo Fighter -$1000 - This VTOL aircraft uses its dual machine guns to take out aircraft.

阿波罗战斗机——1000：这个垂直起降飞行器使用双机枪来对付空军。

The trajectory tracking control for the under-actuated VTOL aircraft with any input coupling was addressed.

研究了欠驱动VTOL空间飞行器在各种输入耦合时的非线性跟踪控制问题。

In the Ramayana: the demon-lord Ravana's flying palace called Pushpaka.

在《罗摩衍那》里面：魔王拉瓦那的飞行器就称为布斯帕卡。

At the Mohenjo-Daro Vimana-drome, as the passenger walks down the concourse, he hears the sweet, melodic sound of the announcer over the loudspeaker,砇 ama Airways flight number seven for Bali, Easter Island, Nazca, and Atlantis is now ready for boarding.

在摩亨佐达罗的飞行器基地上，乘客走下广场，听到了播音员由扬声器而来的旋律优美的声音，七号航线从巴厘岛，复活节岛，飞到纳兹卡，现在准备在亚特兰蒂斯降落。
