Analysis of the results of the well-known experimental researches carried out at the first third of XX century allowed for the first time to create the rational conceptual model of the flow kinematics and the interaction dynamics of the unrestricted uniform flow of real continuous medium – mainly air – with a solid body. The body is presented in a kind of the thin flat plate of the infinite span at any angle of attack. Unity of fields of the flow trajectories and velocities with the force field of the flow action onto the body is achieved by means of orthogonal conjugation of curves from assemblage of conical sections – circumference, ellipse, parabola, hyperbola – in combination with the local continuity condition and with introducing a conception on the jet streams induced by interaction of the body form with the unrestricted flow part running immediately against the body. Forces of viscosity act in accordance with the boundary layer theory in internal and external boundaries of these jet streams. Concrete examples of graphical construction and corresponding calculations show the method of determination of the pressure and rarefaction distribution on the body front and back sides and interaction of these forces between its.
