So, as I understand it, the wing is broken down in sections, each of which will use some tabulated lift and drag for that airfoil at the current velocity vector and dynamic pressure? That seems fine. But it doesn't talk about how it deals with the fuselage and how it calculates its lift/drag. Calculating pressure drag is complicated and depends on the details of the airflow around the fuselage, and there's intersection drag at the interfaces with the wings/empennage. A significant portion of the drag for piston airplanes is also the cooling drag of the air that's forced through the cowling and the engine baffles. Does anyone know to what extent this is taken into account? |
