PT6A/68b and PT6A/68c
Hi everybody,
For my studies i need some information about Pratt & Whitney PT6A/68c engine.
I have some for PT6A/68b, and couldn't find the major differences between /68b and /68c.
Does anybody know why did they call the engine used in super tucano /68c. As much as i know both version are 1600 shp and 4 axial, 1 centrifugal type free turbine turboprops.
I am waiting for your answers, thanx to everybody....

It is possible that the PT6A-68C has a modified Oil Scavenge system to allow the aircraft to perform aerobatics or inverted flight, but as the -68 Series covers both the Texan II and Pilatus PC-21, I suspect that the modified oil scavenge system is standard to the -68 Series.
The C is the most powerful of the -68 Series and having built the -68 and -68B, it would be logical to name the next variant the -68C.
