The Biggest Jet Engine
HOW POWERFUL IS THE BIGGEST JET ENGINE?
By Airline Ratings
Early jet engines
The
first jet engines on the Boeing 707 and Douglas DC-8 produced just 13,000 lbs
of thrust or 20,000 hp. The engine intakes were small and an air hostess could
barely squeeze in for a publicity photo.
Boeing’s
first 747 jumbo had much bigger engines which produced about 45,000 lbs of
thrust. The most recent model, the 747-8, has engines that produce 66,000 lbs
of thrust.
Boeing 777
To
power the 777, General Electric opted to build an all new engine the GE90.
Initial thrust was 96,000 lbs, later increased to 115,000 lbs to power the
larger and longer ranged 777-300ER and 777-200LR.
The
GE90 is in fact as wide as the 737 cabin!
