In this basic lesson, I talk about the types of airflow experienced by a helicopter's rotor system and how they combine to generate lift. I had trouble understanding this beyond a superficial level at first, but it’s pretty straight-forward once you draw it all out.
The topics introduced here are:
- Relative wind
- Rotational relative wind
- Induced flow
- Resultant relative wind
- Angle of attack (AOA)
- Induced flow's effect on AOA
Hopefully this layered visualization approach is as helpful for you as it was for me. I’d love to hear from you in either case. Drop a comment, or click the thumbs up, thumbs down, or subscribe button. Thank you!
