The two counter-rotating tandem propellers provide a simple means to enhance yaw control, which is particularly important in vertical flight. 而机上安装的一对反向旋转的螺旋桨则起到了至关重要的作用。
For centuries man dreamed of achieving vertical flight. 几个世纪以来,人类一直渴望达到垂直飞行(VF)。
His sketch, dated in1493 and discovered in the19th century, shows a vertical flight machine. 达·芬奇创作于1493年的一幅直升飞机的素描于19世纪被发现。
As a example, an optimal design is made in this paper for a vertical flight control system. 作为例子,文中对某纵向飞行控制系统进行了最优设计。
The position control system is decoupled under horizontal and vertical flight. 在飞行机器人进行水平飞行和垂直飞行(VF)时,对控制系统进行解耦。
