Re: How do I solve equations if not knowing the fu

I have equations in terms of aerodynamic coefficients and these are
greater than the equations itself. Now, there is some experimental
data of these coefficients CL, CM, Cn etc etc in terms of the control
variables that I have to find out ultimately. But this data is very
limited , its is at few values and that too the other variable inputs
kept zero. Say rudder deflection of my model is varied but the other
control surface deflections like aileron and elevator is zero
throughout. So I don't have any functional form , neither do I have
the data at evry possible combination of the the variables I have to
findout finally. Even the interpolation through which I can predict
the value of some aerodynamic coefficients at some combination of
control surface deflection will be on an assumption andI have no way
to verify whtehr such a thing is correct or not.
Hopefully I am clear.
