Engine Types and Technical Features

The Boeing 747 has been equipped with a variety of powerful engines throughout its lifespan. These engines, crucial for the aircraft’s performance, represent a blend of technology and engineering prowess. The choice of engine often depends on factors like the aircraft’s variant (passenger or cargo), desired range, and the airline’s operational requirements. Simple Flying’s articles often highlight the engine choices made by different airlines.

Engine Type	Manufacturer	Thrust (lbs) (approx.)	Typical 747 Variant	Notable Features
Pratt & Whitney JT9D	Pratt & Whitney	46,000 – 66,000	-400, -SP	High bypass ratio, reliable, widely used
General Electric CF6	General Electric	50,000 – 60,000	-400F	High bypass ratio, known for fuel efficiency
Rolls-Royce RB211	Rolls-Royce	47,000 – 50,000	Early 747 variants	Three-shaft design, high power-to-weight ratio

The data provided by AviTrader often focuses on the maintenance and operational aspects of these engines. The choice of engine significantly impacts the aircraft’s overall performance, fuel consumption, and maintenance needs.

Different 747 Variants and Engine Configurations

Different 747 variants have different engine configurations, reflecting their intended roles and operational needs. The -400F, for example, is a dedicated freighter variant, while the -SP is a shorter-range passenger version. These differences are often highlighted in articles on Simple Flying and Aviation Pros.

747 Variant	Typical Engine Type(s)	Passenger/Cargo	Range (nm) (approx.)	Operational Characteristics
747-100	RB211, JT9D	Passenger	4,000 – 6,000	Original 747 variant, less fuel-efficient than later models
747-200	JT9D, RB211	Passenger/Cargo	4,000 – 6,000	Improved fuel efficiency compared to the -100
747-400	JT9D, CF6	Passenger	7,000 – 8,000	Significant improvements in fuel efficiency and range
747-400F	CF6	Cargo	4,000 – 6,000	Optimized for cargo operations, high payload capacity
747-8	GEnx	Passenger	8,000 – 10,000	Most modern 747 variant, highest fuel efficiency

Aviation Pros often focuses on the maintenance and operational aspects of these different variants. Understanding the engine-variant relationship is crucial for efficient fleet management and maintenance planning.

Notable Incidents

Several incidents involving Boeing 747 engines in China highlight the importance of rigorous maintenance and pilot training. The University of Bielefeld’s archive provides detailed accident reports, such as the China Airlines Flight 006 incident. This involved a loss of engine thrust resulting in a significant in-flight upset. The investigation revealed the captain’s preoccupation with the engine malfunction led to a loss of situational awareness and control. Another significant incident, reported on Simple Flying, was the China Airlines Flight 358 crash, involving a double engine separation. The investigation highlighted fatigue as a contributing factor to the pylon failure.
