Honeywell’s T55 engine upgrade to provide more power and better fuel efficiency for US Army’s CH-47 Chinook

Honeywell is finalizing a new and improved T55 engine to power the U.S. Army’s Chinook helicopters. The newest upgrade for the legendary T55 will offer over 20% more power at sea level, a nearly 10% power increase at high and hot altitudes, and use 9% less fuel than before. This new variant of the T55 will also greatly reduce ownership costs, improving the overall value of what is already one of the most battle-tested engines in the history of warfare.
