Speed is limited by the retreating wing or blade. ![]() Apart from that, the disadvantage of helicopters are speed and capacity. They also has a smaller rotor at the tail that counter acts the torsional forces created by the torque of the main rotor. This large rotor provides the lift and forward motion to the helicopter. Helicopters have a main propellor blades that turn about a vertical axis. To fly, helicopters have a propellers while airplanes have an engine that provides thrust to push it through the air, which forces air over the wings and create lift that allows the plane to climb. On the contrary, or the differences if you may, is that a airplanes generate lift by moving through the air while helicopters rotate their wings allowing them to generate lift without forward motion. This shows that both are vital elements in the everlasting growth of our future. ![]()
