Semispan Wing Model Testing - Issues & Tunnel Corrections

[RandomGuy88]

Hi, I am wondering if anyone out there has some experience testing semispan wing models in a tunnel. Most of my tunnel experience is 2D testing such as airfoils but I am going to be starting some 3D wing tests soon and I would like to know what sort of issues to expect. For example I have been reading up on the interaction of the tunnel wall boundary layer and the wing root. Are there other potential issues I should worry about that are typical of semispan models? What about tunnel corrections? If anyone has any suggestions on references that would be great.

Thanks!

Read Barlows book on Wind Tunnel Testing. It goes over it in detail.

Hello, I have some experience testing semispan wing models in a tunnel and I can offer some advice. One issue you may encounter is the interference between the wing and the tunnel walls, which can affect the accuracy of your results. To minimize this, make sure your wing is mounted securely and as far away from the walls as possible. You may also want to consider using a smaller scale model if possible. As for tunnel corrections, they can vary depending on the specific tunnel you are using, so it's best to consult with the tunnel operators or refer to their documentation for guidance. As for references, I would recommend checking out the book "Tunnel Testing of Semispan Models" by John D. Anderson Jr. Good luck with your testing!
