1·Chris Retzler has built a prototype of a machine called the wave rotor.
克里斯·雷兹勒做出了一台叫做波转子的样机。
—— 《柯林斯英汉双解大词典》
2·This minuscule rotor wiggled clockwise or anticlockwise as molecules bumped into it from one side or the other.
当分子从一边或另一边撞击这个微型转子时,它会顺时针或逆时针摆动。
3·Think of it as a rotating transformer, with the primary windings residing in a stationary casing (stator) and the secondary conductors attached to an inner shaft (rotor).
你可以把这种电动机当作一个旋转变压器,其主要的线圈在固定套管(定子)内,二级导线附在一个内轴(转子)上。
4·This creates a secondary magnetic field around the cans that is repelled by the magnetic field of the rotor, literally ejecting the aluminium cans from the other waste materials.
这样,被转子磁场隔开的铝罐周围就会产生一个二级磁场,实际上也就能将铝罐与其它废料隔离开来。
5·The three-bladed rotor spins in winds from 7 to 70 MPH, sweeping twice the area of a football field.
当风速达到每小时7至70英里时,便可驱动安装着三片风叶的转子旋转。
1·This means it can hover like a helicopter, but when flying forward can reduce the speed of the main rotor because the wings provide part of the lift.
这意味着它能像一架直升机那样作空中悬停,而在向前飞行时,又能降低主旋翼的速度,因为它的一对短翼提供了部分升力。
2·This means it can hover like a helicopter, but when flying forwards can reduce the speed of the main rotor and let the wings provide part of the lift.
这意味着它能像直升机一样悬停,但向前飞时可能减少主旋翼的速度并让这两个短翼提供部分提升力。
3·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。
4·This means it can hover like a helicopter, but when flying forwards can reduce the speed of the main rotor and let the wings provide part of the lift. Its propellers give the extra oomph.
立方直升机的这种配置让他可以像直升机一样盘旋,但在向前飞行时,主旋翼的转速可以将下来,让两侧的机翼提供升力,在此情况下,两台螺旋桨推进器就能发挥大作用了。
5·Then there's increasing the number of rotor blades. This helps because each additional blade carries less of the weight of the helicopter, and thus produces less noise.
增加旋翼桨叶数量也是一种方法,这使得每片桨叶负载的直升机重量降低了,因此产生的噪音更小。
