The main provisions of the nonlinear vortex method for solving non-stationary problems and the use of the method to determine the aerodynamics of the main rotor (RO) when maneuvering a helicopter are considered. In order to reduce the complexity of calculations, the possibility of using a numerical version of the classical method is also justified, which allows one to determine, taking into account experimental data, the distribution of aerodynamic forces and moments along the span of the NV blades in the general case of helicopter motion.

The article considers the main directions of development of aviation unguided missiles. Further development and perfection is reduced to the fact that aircraft guided missiles are being developed on the basis of the latest samples of unguided missiles. It is possible that such missiles are being tested and may have already been adopted.

The article presents the results of modeling the firing of unguided aircraft missiles with a helicopter series, obtained using the ANSYSCFX software environment for numerical simulation of gas and hydrodynamics. The modeling process involves the construction and study of solid-state models of the Mi-28N helicopter and the S-8OFP missile under the influence of the helicopter's main rotor and the torch in front of the flying missile. The use of modeling results will make it possible to obtain and evaluate the aerodynamic pa-rameters of unguided aircraft missiles under the influence of the helicopter rotor and the torch ahead of the flying missile in the interests of increasing the accuracy of the use of unguided aircraft missiles.
