@.Scott Thanks a Lot! I will surely look into this! @boneh3ad The problem of stability that I had was fixed hence I didn't continue that discussion. However, the graphs of Lift and Drag force were ambiguous hence the experiment was abandoned.

Hello! I am a High School senior planning on doing a project for my Diploma which is based on Aerodynamics. Now, I have looked into the basic physics that goes behind airfoils and their forces. However, I am looking for an experiment idea that is somewhat higher level (maybe undergrad level). I...

@FactChecker Yep I used a dual range Vernier Force sensor for that purpose.

I am also considering building another set of airfoils by using thermocol and a hot wire foam cutter. I believe this would remain more stable and won't rotate in the Wind Tunnel. Is this a good idea?

@FactChecker Yeah that's the problem. It isn't rigid at all! I have tried putting clay around it to make it rigid but didn't work. Is there any other way I can make it rigid. The reason why it is not rigid is because the hole in the airfoil is a bit bigger than the rod.

@anorlunda whenever I put the airfoil inside the test section, it always turned 90 degrees to the side eventually. So I guess what I want is a way to either keep the airfoil still so that the angle of attack is constant and the airfoil doesn't rotates to the side or another way of measuring lift...

Hello guys, I am trying to calculate the lift force and drag force in a wind tunnel at my school as a part of a project that i am doing. I am varying the length of the airfoils and trying to measure the lift force and drag force. I have 3-d printed 7 airfoils. However, I am not able to find any...

I can offer guidance in some areas and I need help as well.

I am looking forward to pursue a career in physics. Currently, I am working on a project in my High School. I would like some help with that. More on that later. Nice meeting you all!
