What do helicopters run on?

Helicopters are typically powered by one or more turbine engines. These engines are similar to those used in jet aircraft, but they are designed to produce more torque and less thrust. The engine(s) drive a rotor, which is a set of blades that spin to create lift and thrust. The rotor is mounted on a shaft that runs through the top of the helicopter.

The engine(s) also provide power for the helicopter's other systems, such as the hydraulics and the electrical system. The hydraulic system is used to control the helicopter's flight controls, such as the cyclic and collective levers. The electrical system is used to power the helicopter's instruments and lights.

Some helicopters also have a tail rotor. The tail rotor is used to counteract the torque produced by the main rotor. The tail rotor is mounted on a shaft that runs through the tail of the helicopter.

The specific type of fuel used by a helicopter will depend on the engine(s) that it is powered by. Some helicopters use gasoline, while others use jet fuel.
