Pages 4 (1004 words)
elicopters are the most flexible vehicle for transport these days. No other transport vehicle or system can give an equivalent level of freedom of maneuverability to its operator.
Focke-Wulf Fw 61 was the first operational helicopter in 1936. A Russian engineer, Igor Sikorsky (1889-1972), designed the first helicopter in 1942 that went into full-scale production phase. Helicopters have found a large number of applications in modern day transportation including military, medical services, tourism, surveillance, fire fighting, search and rescue, etc. Its flight features allow movement in all direction: upwards, downwards, sideways, forward as well as in reverse direction. This flexibility allows the helicopter to be flown in small and congested areas where it is not possible to land the airplanes. Since it can fly in any direction, it has a lot of parameters to take care of while flying. Therefore, the pilot needs to be very skilled and capable and must give full attention while flying. Helicopters not only move in all three dimensions but can also rotate and hover at one point in air. These features, although, make it a unique mode of transport, also make it a very complex machine to understand as well as to pilot. ...
