The article considers the issue of ensuring fire safety on board a modern helicopter. The purpose and composition of the accident-proof fuel system (AFS) are described. The principle of operation and design of such an AFS aggregate as a flame arrester is analyzed in detail. Its hydraulic calculation was carried out, the distribution fields of the total overpressure, velocity vectors and coolant flow lines are presented as the results. An example of using the data obtained in this calculation to construct a one-dimensional mathematical model of an accident-proof fuel system of a helicopter is described.

Keywords:mathematical model, flame arrester, accident-proof fuel system, helicopter.
