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....
