- A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing or short take-off and vertical landing aircraft cannot perform without a runway.How Helicopters Fly and ThrillHelicopters are remarkable machines that can take off and land vertically, hover, and fly in any direction. But how do they work and who invented them?

Main gearbox | SKF
In many helicopter applications, the main gearbox is isolated from the fuselage structure of the aircraft using elastomeric mounts. Various configurations of mounts are used to isolate the vibration from the fuselage.
gearbox changes the direction of axis from the power plant to the combining transmission and reduces the speed. The gearing is spiral bevel with a reduction ratio of 1.23:1.

2.972 How Power is Transferred in a Helicopter - MIT
Depending on a helicopter's arrangement, other drive shafts and gearboxes may be needed at various locations. The main rotor gear box serves to reduce the velocity at which the engine shaft rotates. This is to prevent the tip s of the …
Helicopter Transmission System | Flight-Study
In some helicopter designs, such as the Bell BH-206, the freewheeling unit is located in the accessory gearbox. Because it is part of the transmission system, the transmission lubricates it to ensure free rotation.
