The 747-400 has 3 different engine choices:
600 miles an hour
Internal combustion.
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.
like all other engines they are made/manufactured in a factory on an assembly line or mostlikely now, by machines
High Bypass turbofan engines use pneumatics (air) for starting the engines.
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.
