A generalized mathematical model of dynamic hydraulic processes in the system of supercharging and drainage of the aircraft fuel system, which includes a centrifugal tank and wing tanks, is proposed. In the model, hydraulic processes are considered as quasi-stationary and there is a dynamic change in the structure of the design network of the supercharging and drainage system, the structure of boundary conditions and current pressure and flow limits, where part of the boundary conditions can be set implicitly. The description of the settlement network is presented. Typical calculation options and rules of their use in the calculation of time are highlighted. The general algorithm of calculation is described.
