After putting check valves in a helicopter propeller, more lift can be generated and the density of the helicopter can be reduced.
如果把单向阀植入直升机的螺旋桨中,螺旋桨产生的抬升力会增加。螺旋桨的密度也可以减小。

Putting one set of check valves into the propeller.
植入一组单向阀。

Putting multiple sets of check valves into the propeller, with careful alignment.
有规律,顺着一定方向地植入多组单向阀。

Now it is possible to manufacturer a helicopter that is completely powered by instant-renewable energy. The flyer can stay in the air for a long time without refuel, just like birds that are capable of flying and sleeping in the sky.
这样的话,直升机可以像有的鸟一样,在空中飞很长世间不用加油了。利用立刻再生能源,飞行器可以一飞好几周,睡觉时也在空中飞着。
