If you fly helicopters, you count on Timken. The company has been making bearings, helicopter transmission systems, rotorhead assemblies, turbine engine components, gears and other precision flight-critical components for commercial and military helicopter manufacturers for as long as helicopters have been flying, practically. It has only been in the last eight years, however, that Timken (Booth No. N4836) has been able to provide aftermarket services to the aviation market, according to Larry Shiembob, director, aerospace aftermarket.

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.
