Higher thrust means higher temperatures. The conditions could reach 2100 Kelvin (1826.85 degrees Celsius) at the turbine inlet – 250 Kelvin (250 degrees Celsius) more than those of the M88. Current materials are not able to sustain such conditions.

Consequently, the DGA along with the French national aerospace research center (ONERA), and the engine manufacturer Safran were contracted by the Ministry to accelerate the development of “new metal alloys and multilayer systems for high-temperature applications on turbine blades and disk
