First engine runs performed on A400M
Airbus Military achieved a key milestone in the A400M military airlifter programme when all four Europrop International (EPI) TP400 turboprops on the aircraft were run simultaneously for the first time on 18 November.
The event was the culmination of a series of tests in the previous 72 hours in which the engines and propellers were first turned using ground power with no fuel in the fuel-lines, in a process known as dry-cranking. Then they were turned with fuel in the lines but without starting the engines, known as wet-cranking.
All four of the engines on aircraft msn 01 were successfully run for four hours beginning in the early evening during an operation that lasted for 6.5 hours including preparation. The engines ran at low power settings in ground-idle and flight-idle modes and will be run up to maximum take-off power in further runs planned to take place shortly.
Airbus CEO Tom Enders, who personally witnessed the first full engine run-up, said: "I wish to thank and congratulate the teams who worked extremely hard to reach this very important milestone which paves the way to the A400M First Flight in the weeks to come."
