A Helicopter is a type of rotor-craft in which lift and thrust are supplied by one or more horizontal rotors, each consisting of two or more rotor blades. This allows the Helicopter to take off and land vertically, hover and also to do a lot of amazing things that i will be explaining to you in this series.
Helicopters are referred to as rotary wing as way of distinguishing them from fixed-wing(Aero plane) because it generates its source of life from the rotor blades rotating around a mast.
Helicopters were developed and built during the first half-century of flight, with the Focke-Wulf Fw 61 being the first operational helicopter in 1936.
One of the main advantages of the Helicopter is her ability to generate life without requiring a forward movement. This creates the ability of the helicopter to take off and land without the need for runways. The helicopter also has the ability to fly at lower altitude and hover at zero ground speed.
Helicopters are often used in congested or isolated areas where fixed-wing aircraft are not able to take off or land.
