Welcome back to the our channel, In this feature, we will take a looks behind the incredible power of the C-5 Galaxy, the US largest aircraft in current service. The C-5M Super Galaxy is equipped with five sets of landing gear, 28 wheels, four General Electric CF6-80C2-L1F (F-138) commercial engines. The C-5A and C-5N variants had the Pratt and Whitney TF-39 engines. Those engines had a familiar scream as the engines spun up or prepared to land. I know a guy that flew this beast during his AF career. One of his flights consisted of taking the NR-1 submarine across the country from Virginia to Commiefornia or someplace like that. It astounds me that someone can design an aircraft that can carry such humongous weights! Super High Bypass Turbofans! It's kinda funny to realize that over 75% (or more) of the thrust comes from the bypass air and not so much the jet exhaust! Were these engines ever used on a commercial\civilian planes? This GE Engines has evolved tp power the latest Airliners and Galaxy Heavy lifter C-5M type and Boeing 777-X Aircraft. The Boeing 777-300ER is Only Aircraft operates the Sole GE90-115 Turbofan Engines and Boeing 787-9 Dreamliner Aircraft.
