I completed a wind tunnel test on a NACA 23012 aerofoil last week and am now writing a report on my findings! I need some help with working out the lift Coefficient as i seem to be going wrong somewhere.
Cl= L/.5 ρ Vw² S
To find the lift force i am subtracting the lift force which was...
Why aren't pressure sensors used for measuring forces in a wind tunnel? Why are strain gauges preferred? Is it because strain gages are sensitive?
The lift and drag plates attached to the stinger should feel strain in two directions. How come the strain gage manages to measure the strain of...
Hey,
I'm trying to measure the lift/drag of a wing in a low-speed wind tunnel, the only ways i might know are using a load cell or force probs, but have no idea about how to set it all up and my school doesn't have the material. So please, can u give me any way using simple things to measure...
