Video: A Pratt & Whitney PT-6 Turbine Section Cutaway In Action

The most ubiquitous turboprop engine in the world is the Pratt & Whitney PT-6--more than a hundred versions of it are out there, too. Famed for its reliability, power and flexibility, the PT-6 is on hundreds of models. While the workings of a gas turbine aren't all that complicated, pictures and words don't get the point across very well. This does! Thanks, Pratt!
