🚦Parasitic Drag, composed of Form drag,skin friction drag and interference drag ✈️Form Drag, which is the result of the aerodynamic resistance to motion due to the shape of the aircraft, ... ✈️Skin Friction Drag, which is due to the smoothness or roughness of the surfaces of the aircraft, and ... ✈️Interference Drag, which may occur where surfaces with different characteristics meet (e.g. wing and fuselage) ... 🚦✈️Induced Drag, which is a secondary effect of the production of lift, ... 🚦✈️Wave Drag, which comes into play when shock waves are developed close to the surface of the aircraft in transonic and supersonic flight.
