the fan can be mounted at the engine front for under-wing configurations. The gearbox and the blade variable-pitch technologies were validated in 100 cycles and 70 hours of tests, including 25% at takeoff thrusts of , reverse thrust, and rotor imbalance with a blade weight. Afterwards, it was disassembled in April 2018 to examine each part and refine expected wear predictions. GE Aviation was involved through its Italian subsidiary Avio Aero, providing the gearbox and the low-pressure turbine. To be certified, a blade-out event have to be extremely improbable, less than once every billion flight hours as its RTM carbon fiber fan blades will be supported by the in-service LEAP experience. During December 2019, Safran and MTU announced an agreement to found a 50/50 joint venture to manage the development, production, and after-sales support activities of the new military aero engine intended to power the Future Combat Air System. In June 2021, Safran presented an updated architecture for its RISE open rotor concept, with a single to 144-156 in (365-396 cm) fan with variable pitch blades forward of a row of static guide vanes, to deliver 30,000lb of thrust (133 kN) with 20% better efficiency than the CFM LEAP.
