The CF6’s journey began in September 1967 when GE Aviation initiated its development. A significant milestone occurred in April 1968 when the CF6-6 was chosen to power the McDonnell Douglas DC-10 Series 10 aircraft, marking GE’s entry into commercial aviation.
| Specification | Value |
|---|---|
| Fan Diameter | 86.4 inches |
| Airflow | 1,300 lb/s |
| Bypass Ratio | 5.72 |
| Overall Pressure Ratio | 24.3 |
| Maximum Take-off Thrust | 41,500 lb |
| Weight | 3,379 kg (7,450 lb) |
The CF6 family has evolved significantly, with modern variants like the CF6-80E delivering up to 70,000 lbs. of thrust – nearly double the original CF6-6 model’s output. This remarkable advancement demonstrates the engine’s continuous technological evolution.
Modern CF6 engines achieve up to 15% better fuel efficiency compared to earlier models. The high bypass design, particularly in the CF6-80C2, delivers the lowest fuel burn in its thrust class, contributing significantly to reduced emissions and environmental sustainability.
The CF6 engine’s versatility has made it a preferred choice for various aircraft types, from commercial airliners to military transport planes. Its scalable performance and robust design continue to meet diverse aviation needs, powering both twin-engine aircraft and large four-engine jumbo jets with remarkable efficiency.
The CF6 engine has established itself as a cornerstone of commercial aviation, powering an extensive range of wide-body aircraft. Its versatility spans across multiple manufacturers and aircraft types.
| Engine Variant | Thrust Rating | Aircraft Application |
|---|---|---|
| CF6-80C2B1 | 56,700 lbs | Boeing 747-200/300 |
| CF6-80C2B2 | 52,500 lbs | Boeing 767-200ER/300ER |
The CF6 engine’s capabilities extend well beyond commercial passenger aviation, proving its worth in military and cargo operations. In military service, the engine operates as the F138, specifically modified for the U.S. Air Force’s C-5M Super Galaxy strategic airlifter.
In cargo aviation, the CF6 powers several prominent freighter aircraft:
The CF6 engine continues to demonstrate strong growth potential in the aviation sector. Industry experts, including Aviation Week & Space Technology’s Guy Norris, project an increase in CF6 production from 50 to 60-80 engines annually by 2020, driven by rising air cargo demand and ongoing Airbus A330 deliveries.
This growth trajectory reflects the CF6’s ability to adapt to evolving industry demands while maintaining its core reliability. The engine’s continuous improvement and innovation make it particularly well-positioned to address future aviation challenges, especially in areas of sustainability and operational efficiency.
