some are, but like 99% are propelled by propellors on the top
Actually all helicopters use a main rotor and a tail rotor for lift and stability. Most late model helicopters utilize a jet engine and transmission power train. Not unlike a torbo prop arrangement.
Airplane is a device powered either by a piston engine and prop or by a jet engine.
They are either powered by a turbine engine like a jet engine or a piston engine.
No - Jet propulsion is not needed for the fact that it would suffer from retreating blade stall because of the lack of rotor rpms. They will have to figure out how to get better rpms prior to tackling jet propulsion. They have jet powered helicopters however they are still driven by the rotor system - not pushed by a jet.
Dragster engine powered helicopters
The type of fuel is specific to the type of engine, not the aircraft. Helicopters that have jet engines use jet fuel, and helicopters that have internal combustion engines use gasoline. However the General Electric T-58 had a device in the fuel control that allowed you to burn just about anything from avgas to jet fuel to kerosene.
Answer Nothing more than any other type of airplane or car. Most helicopters are powered by jet engines that use a gearbox to power the rotor blades. The turbine jet engines are relatively evironmentally friendly compared to other internal combustion engines.
Yes. See link below.
It is a jet engine used by airplanes, helicopters and power boats. It is composed of a intake fan and turbine engine. See link below.
They're powered either by a gas turbine engine (known as a turboshaft), or some helicopters (such as the Robinson helicopters) still use internal combustion engines.
you can't get a jet in gta yet only helicopters
Jet-powered aircraft land on the same airports as piston-engine aircraft.
Helicopters can be equipped with either reciprocating (piston) engines or turbine (jet) engines. There is no reason to suspect that advances in electric batteries or hybrid engines will not permit electic motors from powering helicopters in the future as is already done with some small (model) helicopters now.
