Materiales AeroEspaciales: 8. Sistemas y Materiales de Acero En Aeromotores Avanzados
Wholly designed, developed and produced by Snecma (Safran group), the M88-2 powers the Rafale multirole fighter built by Dassault Aviation. It is also the basis of a new family of engines built around a common core.
The M88-2 powers both the air force and naval versions of the Rafale multirole fighter. It is a new-generation engine that features cutting-edge technologies such as a low-emissions combustor, single-crystal turbine blades and powder metallurgy disks. The M88-2 also incorporates the latest advances to reduce its electromagnetic and infrared signature. Its modular design enhances maintainability and contributes to high dispatch reliability. Snecma has developed an upgraded version, the M88-2E4, to further reduce specific fuel consumption and augment the lifespan of critical engine parts, in particular the core and afterburner. These improvements reduce fuel burn by 2 to 4%.
The Turbomeca Arrius is one of a family of turboshaft engines for helicopter use, first produced in 1981. As of 2012, some 2,700 units had been sold. Power ranges between 357 kW (479 shp) and 530 kW (716 shp) for different versions. Following Turbomeca tradition, the Arrius was named after a Pyrenean peak (pic d'Arrius), located in the Ossau Valley near Pau
