Supersonic Elevon Lift Coefficient

[dantheman999]

Does Anyone know how to find the Lift Coefficient for a trailing edge elevon on a delta wing in supersonic flight?

I am trying to compute balance the moments of a tailless delta wing aircraft in supersonic flight. The lift of the delta wing itself is not an issue to find, but the lift of the elevons is very hard to find.

I know I can calculate the pressure differentials using expansion fans + shock waves, but i need a solution in terms of alpha and elevon angle, in order for me to solve for them.

hi dantheman999 my suggestion is cfd. Have u done an analysis using it?or if u have access to windtunnel u can model it and compute the forces involving it.
theoretical solutions may give a value close to the approximate values.
