Flap Hinge Moment Calc
Is there a quick way to calculate what the hinge moment (or turning
moment for the flap shaft for a specified condition) is for a flap on a symetrical foil. |

You don't need to calculate it ...
There is a a number of sources of such data that will be far more reliable than any calculation: * NACA reports (search NACA TRS online) - there is heaps of such reports * USAF Stability and Control DATCOM * Books such as Hoerners Lift, Etkin, Perkins and Hage (I think) will have limited data. * ESDU data sheets There are other sources if you cannot find any of the above ... just ask again and I will give you more.

There are too many details that can have a big effect on hinge moments that
you simply cannot allow for in calculations, such as the shape of the TE, degree of gap sealing etc. People who do this for a living rely on experimental data NOT calculation.
