Pratt & Whitney Canada Delivers New Powerplant For The New Helo

The first PT6C-67E production engine for the Eurocopter EC175 helicopter, a medium-size utility helicopter for multi-role civilian and parapublic applications, has been delivered by Pratt & Whitney Canada (P&WC). "This first production engine marks another milestone in our relationship with Eurocopter," said Richard Dussault, Vice President, Marketing, P&WC. "The first flight of the second EC175 prototype helicopter took place last December, and certification of both the engine and helicopter is slated for the second half of 2011. Entry into service is planned for 2012."

P&WC announced the selection of the new-generation PT6 turboshaft engine family. It incorporates all the lessons learned from millions of hours of PT6 field operation and experience, as well as the latest technology, to provide unparalleled durability and reliable performance. It also features the latest technology dual-channel FADEC control system to optimize pilot workload.

"In keeping with P&WC's green-engine philosophy, the PT6C-67E engine has removed materials of concern, such as cadmium and chromium, from the manufacturing and design processes," noted Dussault. "The engine also includes new combustor technologies to provide reliable starting with excellent emissions, especially low NOx levels, and very low smoke levels."

The PT6C-67E engine uses a reverse flow combustor and features a proven high-efficiency compressor and the latest material and hot section design technologies while maintaining an uncooled CT stage. This optimizes reliability, durability, mission performance, fuel consumption and greenhouse gas (GHG) levels and purchase, operating and maintenance costs.
