The newly certified engines can each produce 105,000 pounds of thrust.
and future of air travel. To push the big 777x forward from a standstill into the air, Boeing needs two big engines that can create literally tons of thrust. Here’s how they break down, by the numbers.Each engine can produce 105,000 pounds of thrust for a total of 210,000 pounds. But Pat Donnellan, an engineer on the GE9X engine program, says that pilots probably won’t need to max the engines out to get off the ground.
The warmest part of the engine is the high-pressure turbine. “It’s right behind the combustor,” he says. To handle that temperature, which is roughly , the engine makes use of ceramic matrix composite materials. “They can withstand temperatures much greater than available metal alloys that are out there today,” Donnellan adds.The fan doesn’t spin in the open air, like a propeller does. It’s encased in a frame. The round material you see at the front of a jet engine is known as the forward fan case. One of the purposes of that case is that it “shrouds” those fan blades’ tips, to create as much efficiency as possible.
