Safran unveils new mechanical power transmission architecture
The power transmission system transfers mechanical power from the jet engine to aircraft and engine equipment that are essential for operation, including the starter, electrical power generator and fuel pump. This energy is tapped from the engine, then transmitted to the accessories through a gear train.
Developed within the scope of the vast European research program Clean Sky 2, the AGB NG features an innovative architecture that facilitates its integration with the engine and nacelle.
Traditionally placed at the edge of the fan, the AGB NG is now located near the high-pressure compressor, in the core section of the engine. Changing this location helps reduce fuel consumption because it allows a smaller diameter nacelle, which in turn reduces aerodynamic drag. The new position of accessories on the AGB NG also reduces the system’s size by 30% and its weight by 20%, in relation to a conventional system. At the same time, the AGB NG simplifies access to accessories, thus facilitating maintenance operations.
The AGB NG is now undergoing a technology maturation program to demonstrate its performance for the next generation of aircraft engines, expected to hit the market towards 2025.
