Lower cost of ownership, greater operability, state-of-the-art control technologies… The Snecma Moteurs M53-P2 is being transformed into the enhanced performance M53-P3 version.
The M53 engine was originally developed to power Dassault Aviation’s Mirage fighters. In 1986, it underwent a first major evolution, from the M53-5 to the current M53-P2 version.
Today, the M53-P2 powers over 500 Mirage 2000 fighters around the world, and has logged over one million hours in flight. But its career is far from over: recent market studies show that the engine will be powering front-line fighters for many years to come.
Mirage 2000s deployed by France (about half of the total fleet) will remain in service until at least 2025, while those deployed by export customers - Egypt, United Arab Emirates, Greece, India, Peru, Qatar and Taiwan - could be in operation until 2030 or even 2035.
Snecma Moteurs asked Mirage 2000 operators what changes they wanted to see in the M53-P2. Based on their answers, Snecma Moteurs focused on two areas: lowering the overall cost of ownership, and a technical upgrade to incorporate state-ofthe-art technologies on the control system and the turbines.
The enhanced engine project was dubbed the M53-P3. Design engineers identified three technical objectives: faster acceleration, improved specific fuel consumption (SFC) and simplified backup systems.
Reducing the cost of ownership depends on increasing the lifespan of hot parts, and simplifying maintainability, especially for the control system.
To meet these goals, the new engine integrates the latest technologies, for instance a 100% full authority digital engine control (FADEC); the control system is now all-digital and fully redundant.
These technologies are derived from those employed on other Snecma Moteurs engines, most notably the M88 and the CFM56.
In addition to the new control system and new turbine, the M53-P3 will also come in an optional higher-thrust version.
For the moment, this mid-life upgrade is primarily targeting the retrofit market. Customers deploying Mirage 2000 fleets will be able to retrofit their engines with the new control system and turbine.
Subsequently, all of these modifications will be applied to original equipment M53-P3 engines.
