Open fan jet engine to power the successor to Boeing’s 737 MAX

An open fan being developed by CFM International, making it a prime candidate to power the next generation of all new airplanes in the mid-to-late 2030s.

The new engine with a giant open fan would change the look of airplanes and provide deep cuts to carbon emissions for the next generation of new jets.

Boeing CEO Dave Calhoun said this month that “you can’t deny both the emission and efficiency gains you get from it.”

In Paris on Friday, Airbus Chief Technology Officer Sabine Klauke said the European manufacturer plans to test fly the open fan aspect of the CFM concept on one of its A380 superjumbo jets around mid-decade.
