Honeywell Aerospace has secured a contract to provide additional engine repair and overhaul support for its T-55 turboshaft engine, which powers the US Army's CH-47 Chinook helicopters.

Under the $30m contract, the company will ensure Chinook operators that the turboshaft engines will perform with the power, reliability and payload capability needed for a broad spectrum of missions in the army's cargo helicopter.

Honeywell Aerospace Defence and Space president Carey Smith said: "With more than 12 million hours of operation on both the CH-47 and MH-47 fleets, our T-55 turboshaft engine has proved it's prepared to support Chinook operators wherever the mission takes them.

"Our commitment extends well beyond the initial delivery of our engines.

"Our team at the Honeywell Greer facility is equipped with the repair and overhaul expertise to limit the downtime of the Chinook and maintain the extraordinary level of performance that the US Army has come to expect from the T-55."

The Army Chinook helicopters are currently powered by two latest configuration T55-714 engines, which deliver 22% more power and use 7% less fuel than its predecessor.

"Our T-55 turboshaft engine has proved it's prepared to support Chinook operators wherever the mission takes them."

According to the company, the Chinooks have three times more lift than the original helicopters deployed in the 1960s, are able to lifting 5t, and possesses 4,800 shaft horsepower, which is needed to maintain flight with only one engine.

To date, the company has manufactured more than 6,000 T55 engines, which are said to have logged approximately 12 million hours of operation on the CH-47 and MH-47 Chinook helicopters.

The engine is claimed to be a valuable tool for the breadth of diverse army cargo missions, from high and hot operating environments in Afghanistan to the polar regions of Alaska.

The repair and overhaul work is scheduled to be carried out at the company's plant in South Carolina, US.
