ATR systems - Powerplant part 1 - General

This is the first video in a series of four videos about the powerplant used by ATR aircraft. It gives a general description of the engine, indications, and a few technicalities that might be nice to know about.

This video is not meant to give a fully detailed description of the system, but to give you an idea about who it works. Despite my effort to be as exact as possible, I might have made mistakes. If you find errors, please let me know, and I will add the corrections here:

1) The drawings show the turbine blades installed in the wrong direction. When viewed from behind, the HP turbine and the power turbine are rotating clockwise, and the LP turbine is rotating counter-clockwise. Here is a video from the engine manufacturer:    • PW127XT engine series: How it works
