The first CFM56 engine with the double-annular combustor entered service in 1995, and the combustor is used on CFM56-5B and CFM56-7B variants with the suffix "/2" on their nameplates. [ 48 ] GE started developing and testing a new type of combustor called the Twin Annular Premixing Swirler combustor, or "TAPS", during the Tech 56 program. [ 29 ]
CFM is the world's largest commercial aircraft engine manufacturer, with a 39% market share as of 2020. [1] It has delivered more than 37,500 of its engines to more than 570 operators.
