    Aerodinamics of Propellers

    Both of small and long propellers have weird aerodinamics. As pictures show, I did some experiments and found that when I put propellers on two side of a block with no rotation change, it fell without spinning despite the angle of 22.5° to the ground. Then I set the propellers horizontal and...

    How do propellers exactly work?

    Hi, at the moment I am learning how to build aircrafts (big thanks to @Shade here). What still is a mystery to me, is how to create enough uplift for your machine while maintaining vertical stability but without putting hundrets of propellers onto it (it wouldn't look like a real aircraft...
