% Drag coefficient for subsonic, supersonic and hypersonic flight.
This combines subsonic, supersonic and hypersonic. All regimes
have a Mach number correction. The skin friction model is selectable.
If gamma is not entered it will be computed from p.
Type CD0Composite for a demo at an altitude of 1 km.
