T55 Turboshaft Engine

T55 Turboshaft Engine

More than 6,000 T55 engines have been produced, logging some 12 million hours of operation on the Boeing CH-47 Chinook and MH-47 helicopters.

Our T55 family of military turboshaft engines began life, as its designation indicates, in 1955. To date, more than 6,000 T55 engines have been produced, logging some 12 million hours of operation on the Boeing CH-47 Chinook and MH-47 helicopters.

At its introduction, the T55 produced 1,600 shaft horsepower (SHP). Several decades and generations of development later, today’s T55 produces 4,800 SHP and powers the CH-47 Chinook to a maximum speed of 196 mph (170 knots).

The latest configuration T55-714 delivers 22 percent more power and uses seven percent less fuel than its predecessor.
