CFM56-7 Turbofan Series of Engines
Celerity Asset Management has a unique focus on the CFM56 family of engines, in particular (with few exceptions) the acquisition of CFM56-7 series on mid- to late-life engines.
CFM56-7 Series of Engines : CFM56-7 series of high-bypass turbofan aircraft engines made by CFM International (CFMI). The CFM56-7 first ran on 21 April 1995.[64] Rated with a takeoff thrust range of 19,500–27,300 lbf (87–121 kN), it powers the -600/-700/-800/-900 Boeing 737 Next Generation; compared to the CFM56-3, it has greater durability, 8% fuel burn improvement and a 15% reduction in maintenance costs. Improvements are due to its 61-inch titanium wide chord fan, 3D aerodynamics designed new core and low-pressure turbine with single crystal high-pressure turbine and Full Authority Digital Engine Control (FADEC). Fan blades are reduced from 36 (CFM56-5) to 24 and it incorporates features from the CFM56-5B such as a double-annular combustor as an option.

Narrowbody Market- 737NG/ A320 CEO Market:
The Boeing 737 and the Airbus A320 families are considered the workhorses of the global
aviation sector. The Boeing 737 NG and the Airbus A320 CEO family both fly CFM-56 engines.
CFM-56 family is designed, developed, and produced by CFM International. The CFM 56-7B exclusively flies on the Boeing 737 NG (100% Market Share). While CFM-56 5 Series (5A and 5B) have a 60/40 split on the A320 Family of aircraft with the V2500 manufactured by International Aero Engines (IAE). With the CFM-56 family of engines having an overall narrowbody market share of 60% delivery over 25575 engines.
CFM 56 – 7 Series Market:
Over 14921 CFM 56 – 7 series engines have been produced as of 2020. The engines were built to support the 737-600. 737-700, 737-800, and 737-900 series of aircraft. An estimated 9550 CFM 56 – 5 B series are in operation.
