Modern defense policies depend on force projection and surveillance. Armed forces have to deploy fleets capable of flying today's logistics and surveillance missions, cost-effectively. Snecma clearly addresses these needs with the TP400 turboprop engine, powerplant of the Airbus A400M military airlifter, and the CFM56® turbofan, which powers Boeing tanker, surveillance and transport aircraft (such as the 737-based C-40).
TP400, the most powerful turboprop in the West
With a 32% workshare, Safran Aircraft Engines is the lead partner in the Europrop International (EPI) consortium, which developed and now produces the TP400, a new-generation turboprop engine purpose-designed for the Airbus A400M military transport. The A400M is a four-engine airlifter, capable of carrying a payload of 40 metric tons (88,000 lbf), and used for military or humanitarian missions to carry troops or equipment, as well as providing in-flight refueling capability.
The TP400 develops some 11,600 shaft horsepower (shp) and offers world-class standards of dispatch reliability and versatility, all at reduced operating costs. The most powerful turboprop engine in the West, it is a key to the A400M's unrivaled capabilities. This aircraft features extended range because of low fuel consumption and its dual civil/military certification means that it can quickly reach theaters of operation since it doesn't have to worry about overflight authorizations.
EPI gives its customers custom-tailored support packages to ensure maximum dispatch reliability, by drawing on the vast industrial resources of its parent companies. Operating thorough EPI, Safran Aircraft Engines is in charge of maintenance for components under its responsibility (combustor, high-pressure turbine, FADEC, accessory gearbox), along with engine removal and module disassembly for certain customers. Safran Aircraft Engines supplies spare parts, also via EPI, along with online technical assistance, and dispatches special tech reps to air force bases

Safran Aircraft Engines, a major contributor to the TP400
Drawing on its recognized expertise in military engine cores, Safran Aircraft Engines was given responsibility for the development and production of critical high-tech parts on the TP400, including the combustor and high-pressure turbine. Safran Aircraft Engines is also in charge of overseeing the integration of other critical parts made by fellow Safran companies: FADEC, the full authority digital engine control (Sagem), the accessory gearbox (AGB) that taps power from the engines to supply energy for other systems (Hispano Suiza), and certain parts in the lubrication system (Techspace Aero). All of these responsibilities give Safran Aircraft Engines a 32% workshare on the TP400.
