The current M88-2 version of this engine powers both the air force and naval versions of the Rafale. Proven in combat, the M88-2-powered Rafale is particularly well suited to low-altitude penetration and high-altitude interception missions.

Light and compact, the M88 features the latest technologies: integrally-bladed compressor disks (blisks), non-polluting combustor, single-crystal high-pressure turbine blades, powder metallurgy disks, ceramic coatings, composite materials, etc.

3D aero design methods are used to improve overall aerodynamic performance, including flowpaths, as well as component thermal and mechanical efficiency.

Thanks to its fully redundant digital control system, the engine displays exceptionally carefree handling and controllability, making it a perfect fit for the multiple missions assigned to today’s air forces.

The M88’s modular design ensures maximum dispatch reliability and highly flexible maintenance. It is the only engine of its generation capable of being repaired, reassembled and directly resuming service without having to be checked out on a test stand. Furthermore, it incorporates the latest maintenance concepts, such as failure diagnosis aid and high-level aircraft/engine integration.

Snecma continuously invests in Research & Technology to keep pace with customers’ evolving requirements, resulting in regular upgrades to the M88.

The new M88-4E version of the engine, culminating the TCO Pack program to decrease total cost of ownership, was qualified in 2011. While retaining the exceptional performance of the M88-2, this new version will significantly reduce total cost of ownership, largely due to new components in the hot section of the engine. The first production-standard M88-4E engines will be delivered at the end of 2011.

The ECO technology demonstrator confirmed that the M88’s thrust could be increased to the 20,000 lb class.
