P&WC’S PT6 engine reaches 400 million hour milestone
Pratt & Whitney Canada’s (P&WC) iconic PT6 engine family has reached the remarkable milestone of 400 million flight hours; well beyond that of any other gas turbine turboprop engine. With over 53,000 engines delivered since 1963, the PT6 has powered more than 140 different applications offering cost-effective and flexible options to the business and commercial transport, cargo hauling and aerial application operations, as well as aiding in deploying humanitarian aid and extinguishing forest fires. Today’s PT6 is up to four times more powerful, has a 50 per cent better power-to-weight ratio and up to 20 per cent better specific fuel consumption compared to the original engine. Improvements throughout the years have allowed the engine to lead, never follow. As the engineering team expanded the engine’s power and capabilities over the years, P&WC repeatedly created a new view as to what was possible.
