The concept of fuel system's mathematical modeling based on certification requirements

The article discusses the concept of fuel system's mathematical modeling based on certification requirements. A detailed description of the safety of aircraft operation, taking into account the standard of airworthiness, and methods for conformity assessment of certification has also been presented. The development concept modeling is not possible to without a methodology to construct an integrated mathematical model which presents a solution using a one-dimensional and three-dimensional functioning model. The combined calculation in a one-dimensional and three-dimensional setting allows the modulating of the refuelling process with drainage system, signaling and centralized fuelling management process. Also as the calculation results of simulation of fuel flow from tanks when one pump fails are shown. Dynamic simulation of fuel production from tanks for calculation of static change fuel static moment and geometric modelling of non-working and non-poured remainder also presented. The article analysed fuel system requirements. This conformity can be met using a complex of mathematical modeling tools.
