Wind tunnel, a tunnel where planes are born

[@noneNone-mw1px]

If the actual speed for real air raft for example is .8 M , do you apply the same wind current for maket in wind tunnel?

[@WilliamScheetz]

I also had this question but he states early that the wind speed goes up to 250kmh so I assume that if the model is scaled the lift factors are also.

No, the similarity theory let you simulate phisical effects using different phisical conditions. The important thing Is ti achieve similarity through a series of non dimensional coefficients, such as drag coefficent, lift coefficient, reynolds Number for incompressible flow, or mach Number for compressibile flow and so on

To have the good and consistent result for scale model in a wind tunnel, you have to aplly in the equation, a new factor, the "Reynolds number" adjusted to the scale of the model. The Reynolds number is about kinematic viscosity (interaction between the skin and shape of the objetc and the fluid) of air or any fluid, in short.

Why are the planes hung upside down

[@TXNWS]

India have its own hypersonic wind tunnel

What is hypersonic i know just super-sonic trans-sonic and sub-sonic
