Abstract

The main mistake that Professor Nikolay Yegorovich Joukowski has committed in formulating the Kutta–Joukowski theorem, formula (1), is the introduction of such an incorrect notion as circulation, .

The Kutta–Joukowski theorem, derived by Professor Nikolay Yegorovich Joukowski, does not stand up to any criticism, as it absolutely does not agree with experimental data of the modern theory of jet engines, where it, formula (1), is incorporated as fundamental. This is due to the fact that under such a concept as circulation, , the maximum pressure of blowing flow on the blade of blowing profile is where circulation is maximum, that is on the outlet edge of blowing profile, and zero pressure of blowing flow on the blade of blowing profile is on the inlet edge, as on the inlet edge .Such a diagram of pressures of blowing flow on the blade of blowing profile, generating a gradient of static pressures, directed against the flow, is in direct contradiction with the experimental data of modern theory of jet engines, which declare that the maximum pressure of blowing flow on the blade of blowing profile is within the inlet edge and this pressure is gradually reduced as blowing flow is displaced to the outlet edge of blowing profile, thus forming the pressure gradient directed along the flow, [1]. Therefore, the Kutta–Joukowski theorem, derived by Professor Nikolay Yegorovich Joukowski in 1912, is incorrect and can not be fundamental for any theory, this theorem should be formulated in the other way, which is described in the paper.
