In article discusses the modeling problems the behavior of underwater vehicles, based on the analysis of which it was established that insufficient attention is paid to the influence research of the vehicle configuration on the immersion and ascent processes. The mathematical model development for optimal control of the immersion and ascent processes, taking into account the influence of the vehicle configuration on the basis of the accepted assumptions, is considered. The mathematical model is a Cauchy problem in the form of a system of second-order ordinary differential equations with initial conditions. The system of equations solution is described based on the Euler method with control of the time step. A software with a graphical user interface has been developed for numerical simulation. The ascent process modeling of the project 945 В«BarracudaВ» submarine is considered as an example. Regularities that can be used to develop an optimal strategy for controlling the immersion or ascent processes of a submarine are identified based on the analysis of the numerical experiments results.
