A strong partnership

Europrop International partnership on TP400-D6

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.
