OK, I need enough accuracy to run experiments such as plotting CL and CD vs. angle of attack. :biggrin:
I'm trying to use load cells or strain gauges that can be hooked up to digital readouts.
Need some mechanical contraption that can isolate the lift and drag forces as much as...
I have constructed a wind tunnel with approximately 15 x 15 in. cross-sectional area test section.
Where can i get some ideas/plans to build a simple force balance that can measure lift and drag forces simultaneously?
Currently I'm using a single-axis button load-cell setup to measure...
