TP400-D6 engine
The most powerful turboprop engine in production
A strong partnership
Facts & FiguresThe TP400-D6, a key to the A400M's unrivaled capabilities
High speed
Delivering an output of more than 11,000 shaft horsepower at sea level and a three-shaft configuration combining state-of-the-art engine modules
LONG RANGE
With a high autonomy of 4,800 nm (8900 km), the TP400-D6 can power extended round trip sorties from its main operating base
HIGH TECHNOLOGY
To optimise engine utilization and enable post-flight troubleshooting, the engine benefits from a dual Full Authority Digital Engine Control (FADEC)
HIGH ALTITUDE
Operating up to 40,000 ft
MODULAR DESIGN
Interchangeable modules improve engine availability for operational support and efficiency for all maintenance activities
CIVIL CERTIFICATION
First military engine to be fully civil certified from the outset by EASA in 2011.
The TP400-D6 has completed more than 400,000 engine flying hours (EFH) in May 2021.How does it work
