The 747-400 has 3 different engine choices:
The diameter of a Boeing 747 engine varies depending on the specific engine model, but the Pratt & Whitney PW4000, commonly used on the 747, has a diameter of approximately 98 inches (about 2.5 meters). The General Electric CF6 engine, another common option for the 747, has a similar diameter. Overall, the engines are designed to be large to provide the necessary thrust for the aircraft's size and weight.
600 miles an hour
Jet engine power ratings are generally in terms of thrust, not torque. The 747 has undergone several engine redesigns. The Pratt & Whitney JT9D engine series varies from a maximum thrust of 46,300 to 50,000 lbf.
Internal combustion.
like all other engines they are made/manufactured in a factory on an assembly line or mostlikely now, by machines
The Boeing 747 uses four engines.
A Boeing 747 has four engines.
The Boeing 747 has at least 4 engines.
747-400 its has more engines...
Four.
It has 4 propulsion engines and one APU.
the Boeing 747-400 because it has 4 engines not 2
A 747 has 4 engines, the 777 has 2.
The 747 because the 757 is much smaller and can carry less passengers. It also only has 2 engines where as the 747 has 4.
The 747-200 has engines rated at 55,145 pounds of thrust. This equated to 87,325 hp.
The thrust generated by the engines of a Boeing 747 is typically around 56,000 to 63,000 pounds-force per engine. Each Boeing 747 aircraft is powered by four engines, so the total thrust produced by all engines combined is roughly 224,000 to 252,000 pounds-force.
The Boeing 747-400 series have a PW4000 turbofan engine aircraft. Each 747 carries 4 of them; 2 on each wing.
