Helicopter is a type of rotor-craft, and in this the engine driven rotors provide the lift and thrust to the helicopter. Helicopters enable us to do achieve many tasks pragmatically and in an effective manner which a fixed-wing aircraft would not be able to do. Helicopter can take off and land vertically and can also fly forward or backward. These are used in myriad military operations and other tasks like saving lives of people in a catastrophic situation for e.g. flood. It can remain still in the air for much time and this facilitates the soldiers to perform various activities which otherwise would not be possible.
