I can barely remember a day I have not encountered blade ever since I have entered into aerospace.
Blades and aerofoils are like atoms for the aerospace industry. They are everywhere.
With my back to basics theme of last month, I went back and reviewed the blade and it’s nomenclature.
This PowerPoint below explains the blade nomenclature of a blade. Posting it here in the hope that it might be helpful to someone.
download it from here
Here’s the video of the powerpoint, in case you do not like to download.
Update: Watch this in a better way with this animated Gif
