Depending on the aircraft's architecture, power is transferred to the main motor either mechanically or pneumatically. Safran Power Units designs and manufactures a wide range of starters for both modes. It also makes valve systems for engine air turbine starters.
Safran Power Units provides the starting systems for TP400 engines on the Airbus Military A400M and SaM146 engines on Sukhoi's SuperJet 100.
Associated with the Saphir 10 APU, the ATS 323 air turbine starter, in a very short time, start the Safran Helicopter Engines / Rolls-Royce Adour Mk871 jet engine installed on the BAE SYSTEMS Hawk advanced training aircraft.
The result of Safran Power Units' know-how in starting systems, the ATS 323 benefits from proven technology that allows for several million starts.
Light and compact, the ATS 323 air turbine starter accepts high air inlet temperatures. Associated with the Opale 3 APU, it provides the aircraft with complete self-sustained starting. It contributes to safety in operation by providing additional starting capacity in flight for the main engine.
