The composition of total Drag as it is shown below:
Graças ao DRAGBUSTERS ... Este documento pode resolver esta questão, e analisa o arrasto em detalhes.
Profile Drag Definition: Profile Drag is the drag incurred from frictional resistance of the blades passing through the air. It does not change significantly with angle of attack of the airfoil section, but increases moderately as airspeed increases. Taken from here.
Definições de arrastar perfil como estão nos dicionários:
The portion of the wing drag that is due to friction and turbulence in the fluid and that would be absent if it were nonviscous
The part of the drag on an aerofoil or aircraft which arises directly from its profile and from skin friction (i.e. the part not attributable to lift).

Form Drag Definition: Drag which depends on the shape of the aircraft, is called form drag.
A seguinte definição foi retirada de aqui .
Profile Drag or, sometimes called form drag, is the drag caused by the separation of the boundary layer from a surface and the wake created by that separation. It is primarily dependent upon the shape of the object. Form or pressure drag is caused by the air that is flowing over the aircraft or airfoil.
E, finalmente, os tipos mais comuns de arrasto encontrados são
Parasitic Drag, composed of
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)
Arraste Induzido, que é um efeito secundário da produção de sustentação e
Wave Drag que entra em jogo quando ondas de choque são desenvolvidas perto da superfície da aeronave em vôo transônico e supersônico.
