The purpose of the work is to develop methods and calculation methods for investigating aerodynamics, obtaining new knowledge about the laws and specific features of processes that are investigated on the basis of non-stationary Navier-Stokes equations and process models. Methods of investigation - methods of numerical integration of differential equations in ordinary and partial derivatives, Navier Stokes equations, experimental studies in an aerodynamic tube. The results of the work are new numerical methods, which in their efficiency and accuracy exceed the known in world practice, and, with their help, the systematization of subsonic and transonic flow of profiles has been carried out. New regularities of modes of flow profiling have been determined, new regularities and specific features of the processes occurring in the transaxial flow of profiles, wings and aircraft cabin aircraft, which will be useful for increasing the safety of flights of civilian and military aircraft, helicopters, small aircraft, etc., are determined. The developed scientific and methodological support takes into account the influence of the icy elements that grow on the streamlined surfaces during the flight under the conditions of glaciation, on the aerodynamic characteristics of the wing profiles, and also the possible auto-oscillations of local jumps of the seal in the conditions of the unsteadiness of the flow field. The glaciation regimes have been studied and a corresponding classification has been compiled. The ways of perfection of aerodynamic form of small aircraft are determined. The sphere of implementation of the results of work - aviation, space technology, power engineering, wind energy, transport, metallurgy, education.
