So in forward flight each rotor can produce an equal amount of lift on each side , thus providing balance .
这样向前飞行时每个转子在每侧都能产生等量的升力，从而保持了了衡。
Although nasa has not yet released the full result , the noise difference between the two aircraft could dampen enthusiasm for open rotor engine technology .
尽管nasa并未透露全部结果，但两架飞机间的噪音差距就足以浇灭对开放式转子发动机技术的热情。
Such machines are known as asynchronous motors , because the rotor 's magnetic field never catches up with the stator 's field .
