Basic concept of how a helicopter flies

Helicopters fly in a completely different way than aeroplanes. Their wings is fixed firmly to the fuselage and as the whole aircraft moves forward, air passes over the wings producing lift and carry  the aircraft into the air. The rotor blades rotate causes air to passes over them as they do creating lift. This, so called rotary flight, is inefficient because their rotorers have to spin all the time to keep the machine in the air but because of rotary flights helicoptes can fly without actually moving forward. THEY CAN HOVER.
