The helicopter is a multi-use versatile aircraft that has been used in combat, search and
rescue, troop carrying, evacuation, and disaster relief purposes. Helicopters are designed and
built to be controllable. Aircraft are designed and built to be stable. Helicopters, unlike fixed
wing aircraft, obtain the required lift force to oppose weight from rotational movement of the
Understanding how lift is produced by rotating blades is difficult for some, because the airflow,
which ultimately passes each rotor blade, consists of a number of seemingly conflicting
airflows, produced by rotation of the rotor blades, induced action, and airflow because of
forward or sideways flight.
Notwithstanding the difficulties, it is important that you understand the cause and the effects of
these airflows, and their interaction to the lift created. This is achieved by the Flying Control
Systems and Sub systems and associated systems to allow the Helicopter to move in all 3 axis
and paths of flight.
