Similar question was asked by a female student from the same dept in UMP..why can,t discus with her.

Hafiz,

Could you please give more detail of the experiment that you are designing for?

Is it to measure forces of a aerofoil/wing? Or to understand how pressure around the aerofoil/wing would be transformed to forces acting on the aerofoil/wing? Or, are you just looking into flow characteristics in the element of the rig?

The next thing you have to decide before hand is, how automated the rig would be? This question is important because, if it is intended for students' understanding of the fundamentals of fluid forces, then automation would not be good. But if is for research, then automation is good.

And then, is the whole scheme is for static case, or dynamic? When I say static I mean the measurements would be done when the system are constant, not changing with time.

When these are clear, may be help would be more forthcoming to you.

Mr. Wan Zaidi Wan Omar, thank you for your reply to my question.

I want to understand how pressure around the aerofoil/wing would be transformed to forces acting on the aerofoil/wing and measure the force using a sensor to collect the data for my research.  The system are dynamic.

Thank you.

As Lim Pei Xuan from the same dept ask the similar question and I had given her quite a comprehensive explanation so please refer to her or team up with her.

Well if you want to understand how lift /drag forces developed from pressure distribution around the aerofoil well  then you have to drill pressure taps into the aerofoil ,both pressure and suction surfaces .

If ypou are looking for system with direct valeus of forces then a simple three cpmponents balance could be constructed.
