Ok, yesterday- to my shame, I said the Russian Mi-24 HIND helicopter could fly without rotating its main rotor - and by pitching the rotor's propellers against the direction of movement, thus effectively working like an airplane's wings. Also the pilot can vector downwards the turbine's engines, giving it partial lift. It was a joke, but some guy got really worked up by it, So anybody who understands a helicopter rotor will know that even in a fully articulated rotor system, you can not have a wing effect.
when there is a problem, Helicopters can to a limited extent -glide without power by using the momentum in the rotors, while using downward motion to force air through them. The main rotor acts like a windmill and turns. This technique is known as autorotation. A transmission connects the main rotor to the tail rotor so that all flight controls are available after engine failure. Autorotation can allow a pilot to make an emergency landing. But do you know of any bigger myths?
