Who Builds Boeing's Jet Engines, And Are They The Same As Airbus Uses?

American aerospace elephantine Boeing has taken a spot of tarnish of late. A brace of deadly crashes and different lesser malfunctions person sullied the reputations of the latest iterations of the brand's 737 Max aircraft, but those concerns don't widen to the jets' almighty engines. Boeing is liable for gathering the 737's iconic flat-bottomed nacelles, oregon casings, which location the engines. However, the turbofan powerplants themselves are farmed retired to assorted planetary manufacturers. The world's largest shaper of pitchy engines, including for Boeing, is simply a associated task called CFM. The 2 entities down CFM are General Electric and the French shaper Safran.

As portion of its 39% planetary marketplace share, CFM's fuel-efficient Leading Edge Aviation Propulsion (LEAP) engines powerfulness each 1 of Boeing's 737 Max aircraft. Coincidentally, engines from this marque tin besides beryllium recovered connected some Airbus A320 jets, a rival to the 737 that's assembled mostly successful Europe. 

Of course, Boeing doesn't conscionable physique the 737. Other commercialized Boeing jets see the venerable widebody 777 and the high-tech 787 Dreamliner, some of which are staples of long-haul oregon high-capacity routes, specified arsenic betwixt the United States and Europe. And the engines determination are made by others.

Before Rolls-Royce started selling bougie onshore yachts, it was known for its airplane engines. For example, its Merlin motor was a unit to beryllium reckoned with successful combatant planes during World War II. Over 120 years since its inception, Rolls-Royce is inactive successful the aeronautical assemblage with a 12% marketplace share. In particular, its products tin beryllium recovered successful galore long-haul widebody jets.

Rolls' Trent 1000 powers immoderate Boeing 787 Dreamliner jets, and Rolls says the level is 25% much fuel-efficient than its predecessor, the Boeing 767. Rolls-Royce engines besides propel immoderate examples of the widebody Boeing 777, the fuel-guzzling double-decker 747, and what remains of the largest single-aisle pitchy ever, the Boeing 757. Like CFM, Rolls-Royce prefers to diverseness its clientele and happily accepts motor purchases from Airbus, excessively — for example, the Airbus A330 and A350 long-haul jets.

Next up is General Electric, which besides has a reasonably tiny — astir 14% — share of worldwide pitchy motor manufacturing. That's understandable, since astir of its engagement successful aerospace is via the CFM associated task with Safran. Alone, GE turbofan engines look connected some Boeing and Airbus products successful tiny quantities. Especially the Boeing double-aisle widebodies.

Finally, we travel to Pratt & Whitney, a veritable instauration successful American aviation since 1917. When it's not gathering engines for combatant jets oregon cruise missiles, P&W captures astir 35% of the marketplace for commercialized pitchy engines. That includes a beingness astatine immoderate level successful astir each Boeing products, excepting newer models similar the 737 Max and 787 Dreamliner. P&W sells to Airbus, too. Notably, its engines are the lone ones utilized successful the new-ish A220 narrow-body jet, a feather successful the company's headdress to beryllium sure. 

So determination you person it. Boeing uses 4 sources to procure pitchy engines for its planes: CFM, General Electric, Pratt & Whitney, and Rolls-Royce. And not a azygous 1 of those companies has a occupation crossing the aisle to merchantability to rival shaper Airbus. Clearly, immoderate passengers similar 1 craft marque oregon different — for example, avoiding airlines with the largest Boeing fleets pursuing an atrocious 2024 for the brand. However, nether the motor nacelles, there's small quality to beryllium had betwixt the 2 craft giants.
