Aerodynamics Questions
Hi all,
Just got a few questions about basic aerodynamics:
1. How many types of drags are there and what are they, and how are they formed?
2. What is boundary layer, how are they formed and what use do they have?
3. How many types of draft are there and how are they created?
4. What is a Mach number used for in terms of scaled down aircraft?
5. How do we work out the Reynolds number and what are they used for?
Also how are they all linked up?
Thanks in advance. Need this for an exam and they are a few concepts I can't really grasp.
Thanks alot
Regards
Brendan
