Helicopter efficiency
WebThe helicopter solution can provide solutions that fixed-wing cannot: savings on DOCs, significantly reduced flight planning and runway independence. The helicopter serves as a complement to an existing corporate flight department, or is an operationally efficient solution for starting a flight department for business travel. A helicopter is a type of rotorcraft in which lift and thrust are supplied by one or more horizontally-spinning rotors. By contrast the autogyro (or gyroplane) and gyrodyne have a free-spinning rotor for all or part of the flight envelope, relying on a separate thrust system to propel the craft forwards, so that the airflow sets the rotor spinning to provide lift. The compound helicopter also has a separat…
