    Embeded rotor oriented craft

    Just as C++ language, now I introduce the new concept, It Is the result of rotor revolution: Bisercrat : Bi-system-embeded-rotor-craft The great breakout is: Solute the method of embeding rotor If It succed, It will bring the industrial revolution, moster than steam enginge

    DONG090909 Conjecture when the rotor has forward speed

    1. First guess The conditions for the lift balance of the coaxial anti-propeller rigid double rotors are: the upper and lower rotors are in the same phase Proof method: Junior high school mathematics and physics: vector analysis of forces 2. Second conjecture (an extreme case of the first...

    Rotor revolution

    1. I respect Sikorsky, but this does not affect my skepticism about his company, working in the rigid rotor field. 2. I think Sikorsky may be wrong on the following points: A. The rotor should not be used for flight, the efficiency is too low, it is best to only use it for lift Of course, the...
