% 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. Since version 2014.1 -------------------------------------------------------------------------- Form: [cD0, cDW, cDF, cDP] = CD0Composite( m, d, alpha, p, gamma ) -------------------------------------------------------------------------- ------ Inputs ------ m (1,:) Free stream Mach number d (.) Data structure .length (1,1) Characteristic length (m) .oswaldEff (1,1) Oswald efficiency factor .aspectRatio (1,1) Aspect ratio .cDM1 (1,1) Drag coefficient at Mach 1 .mDD (1,1) Drag divergence Mach number .thicknessRatio (1,1) Thickness to chord ratio .model (1,:) Skin friction model alpha (1,:) Angle of attack (rad) p (.) Standard atmosphere data structure gamma (1,1) Ratio of specific heats, optional ------- Outputs ------- cD0 (1,:) Drag coefficient cDW (1,:) Wave drag cDF (1,:) Skin friction drag cDP (1,:) Pressure drag -------------------------------------------------------------------------- See also CDWave, CPHypersonic, CDSkinFriction --------------------------------------------------------------------------
