我的飞行机器既没有翅膀也没有螺旋桨，您可能会看到它在地上，和你绝不会猜到它是一架飞行机器。
My flying machine will have neither wings nor propellers. You might see it on the ground and you would never guess that it was a flying machine.
那么其他的一些飞行器，比如说直升飞机，螺旋桨飞机，他们没有喷气式引擎，可以在这种条件下飞行吗？
So can other aircraft, such as helicopters or prop-planes that don't have jet engines, fly through these conditions?
他没有在飞行过程中看到火或烟，他认为螺旋桨在旋转。
He saw no fire or smoke during the flight and he believed both propellers were rotating.
即使有一个好的发动机，如果没有合适的螺旋桨来带动，飞机的性能也会大打折扣。
Even if has a good engine, if does not have the appropriate propeller to lead, the airplane performance also can sell at a discount greatly.
应该指出，强调在这本书是关于在涡轮喷气发动机，并没有特殊的部分涉及与螺旋桨涡轮发动机。
It will be noted that the emphasis in this book is on the turbo-jet engine and that no special part deals with the propeller-turbine engine.
有一个神话说高度抛光的螺旋桨工作得更好-它没有。
There is a myth that a highly polished propeller works better - it doesn't.
主要是因为现在还没有普遍适用的船用螺旋桨的设计和绘图方法。
