因此在向前飞行时，旋转叶片可以在每一边产生相同大小的升力来进行机身的平衡。
So in forward flight each rotor can produce an equal amount of lift on each side, thus providing balance.
它由两个喷气涡轮引擎提供动力，以驱动五个叶片的主旋翼，以及通过齿轮箱和连轴驱动在两边短翼上的一对螺旋桨。
It is powered by two jet-turbine engines which operate both the five-bladed main rotor and, through a gearbox and shafts, a pair of propellers on two short wings.
它的叶子和茎是绿色的，叶片光亮而厚实，还有齿边。
Its leaves and stems are green, shiny leaves and thick, as well as tooth edges.
本系列风机的叶片采用特殊扭曲孤度设计，机壳采用法兰翻边工艺，使风机噪音更低，风量更大等特点。
SF (b) series adopt special twisted blade design and flange flanging casing, which makes the noise lower and the air volume larger.
结果表明，该叶片掉块性质为烧蚀掉块，烧蚀掉块的原因是叶片排气边局部出现瞬时高温。
High temperature of the local exhaust edge of the vane led the vane to ablate and fracture.
首先对叶片进气边分区进行了模拟外来物损伤试验，并对外伤叶片和损伤后的修理叶片分别进行了疲劳试验。
Firstly, simulated . experiments of FOD on the leading edge of the blade were performed. Then, the damaged blades were fatigue tested.
