PT Dirgantara Indonesia (PT DI, Indonesian Aerospace) expects to fly its N219 twin-turboprop transport next year. The aircraft has been under development for some time to answer a need for a rugged STOL airliner able to operate in and out of remote, semi-prepared airstrips. At the same time, the N219 is intended to provide cost-efficient and reliable operations through the use of modern avionics and engines.
It’s the little engine that thought it could. And so it did. Fifty years and more than 41,000 engines later, the PT6 from Pratt & Whitney Canada is in use by more than 6,500 operators in 182 countries. Compared with the original PT6, the latest PT6A is four times more powerful, has a 40 percent better power-to-weight ratio and 20 percent better fuel consumption. Did we mention safety? The current in-flight shutdown rate is one event per million flight hours. Heli-Expo visitors can help Pratt & Whitney Canada celebrate the PT6 50th anniversary today at 12:30 p.m.
Pratt & Whitney Canada provided an update yesterday at NBAA 2011 in Las Vegas, addressing several programs and projects in development.
