STS
Safran Transmission Systems is a key company in the aerospace power transmission market, with over 60% market share for commercial aircraft with more than 100 seats, more than 50,000 transmissions delivered to date, and over 1 billion flight hours logged.
We design, certify, manufacture, and support aerospace power transmissions for the civil, military, and business jet markets.
The mechanical transmissions designed and produced within Safran Transmission Systems perform several essential functions of the aircraft propulsion system :
• Transmitting the mechanical power of the turbomachine to the various engine accessories (fuel pump, lubrication unit, etc.) and aircraft accessories (electric generators, etc.)
• Driving the turbomachine during startup using the starter motor - Managing transient load transmission phases during energy generation/recovery on hybrid systems
• Decoupling the speed of the propulsion module (fan) from its drive system (gas turbine) using a power reducer.
With essential modules in the new propulsion system architectures, Safran transmissions are at the heart of product performance and energy efficiency challenges.
