Suitable mechanism for changing the angle of attack of an airfoil

AI Thread Summary
For conducting wind tunnel tests on a NACA 0015 symmetric airfoil, a suitable mechanism for changing the angle of attack includes options like a 4-bar linkage or a stepper motor. Numerous academic papers provide insights into various mechanisms used for this purpose. The problem of adjusting the angle of attack is considered straightforward by many in the field. Exploring these mechanisms can lead to effective solutions for wind tunnel testing. Researching existing literature will further enhance understanding and options available.

I have to conduct wind tunnel test on a naca0015 symmetric airfoil at different angles of attack and I am in search of a suitable mechanism to change the angle of attack of the airfoil.Please help.
 
Physics news on Phys.org
There are many, many papers written on the subject. I'd suggesting looking a few up.
 
Ever heard of a 4-bar mechanism? Or a stepper motor? This seems like a very straightforward problem to me...
 

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
