Few airlines demonstrate the latest trends in air transportation better than does Indonesia’s Lion Air. The fast-growing carrier opened for business in 2000, flying to domestic destinations and nearby foreign airports in Singapore and Vietnam. Today, its fleet consists almost entirely of single-aisle aircraft like the Airbus A320 and Boeing 737, with hundreds of the next-generation versions of the planes on order.

Standing on the Shoulders of a Giant: The World’s Largest and Most Powerful Jet Engine is Getting Bigger

June 17, 2015
Building something new usually takes a lot of brains, effort and time. When GE decided to put blades made from untested carbon fiber composites inside a brand new jet engine, replacing titanium with what was essentially plastic, it also required a lot of nerves.
“The design team woke up every morning thinking about it, and went to bed every night thinking about it,” says David Joyce, chief executive of GE Aviation. “It was such a radical change in design.”

Come Dust, Ice, Hail Stone and High-G Force: What it Takes for the LEAP Jet Engine to Prove its Mettle

June 14, 2015
The sand storms in the Gobi Desert in Central Asia are some of the most frightening events nature can cook up, sending giant tan clouds of fine dust as far as Beijing. While locals seal their homes and try to keep the dust away, Gareth Richards, program manager for the next-generation LEAP jet engines at CFM International, can’t get enough of it.

These Space-Age Ceramics Will Be Your Jet Engine’s Next Cup of Tea

May 15, 2015
Humans have been living with ceramics for 25,000 years. We’ve been using them for cups, pipes, pottery and many other handy everyday objects. But the light, strong, and heat resistant material has one fatal flaw, which has kept it confined mainly to the cupboard. “When you hit it, it fails catastrophically,” says Krishan Luthra, chief scientist for manufacturing and materials technologies at GE Global Research in New York. “I thought it would be the Holy Grail if we could get it inside machines, and get more power and savings out of our engines. It could really make an impact.”
