Honeywell improving T55 engine
Honeywell is working on new engine improvements to power the CH-47 Chinook helicopter, the company announced on 14 October.
The upgraded T55 engine introduces advanced compressor technology, offering over 20% more power at sea level, a nearly 10% power increase at high and hot altitudes, and the use of 9% less fuel than before.
Being carried out by internal company funding, the upgraded ‘drop in replacement’ engine will be able to integrate with the Chinook’s existing nacelle and maintain all the same connections to the aircraft. No changes to the helicopter engine mount or engine interfaces will be required.
According to the company, the engine upgrade will also be fully compatible with the US Army's existing T55 infrastructure, tooling, support equipment and organic capabilities.
Dave Marinick, vice president, engines, Honeywell Aerospace, said: ‘Honeywell is committed to continually improving the T55 engine to meet military needs and developing reliable, time-tested engines that require less maintenance and can withstand harsh environments. Our dedication in continually improving the T55 is a testament to more than five successful decades working alongside the US Army to protect and serve its soldiers.’
The new offering will be available as both a new engine version and a low-cost kit to upgrade engines during overhauls.
