* Different Engine Types: Boeing 747s have used a variety of engines throughout their history, including the Pratt & Whitney JT9D, General Electric CF6, and Rolls-Royce RB211. Each engine type has its own horsepower output.
* Engine Variants: Even within the same engine type, there are different variants with varying horsepower.
Here are some examples of engine types and their horsepower:
* Pratt & Whitney JT9D: 43,000-48,000 horsepower (per engine)
* General Electric CF6: 52,000-60,000 horsepower (per engine)
* Rolls-Royce RB211: 45,000-50,000 horsepower (per engine)
To get the total horsepower for a specific Boeing 747, you would need to know the exact engine model installed on the aircraft.
For example, a Boeing 747-400 with four General Electric CF6-80C2B5 engines would have a total horsepower of approximately 240,000 (60,000 x 4).
Important Note: Horsepower is often used to measure engine power, but in the aviation industry, thrust (measured in pounds) is a more common measurement.
