The paper presents the results of the analysis of the simulation tests of the flow of fuel through the fuel rail for the designed radial aircraft engine. A 3D model has been developed for CFD calculations including the fuel rail and elements supplying the fuel to the injectors. Simulation tests were carried out using Star-CD software. The objective of simulation tests has been to determine flow characteristics of the fuel rail design. This design is atypical due to: the shape of the rail - a torus with internal diameter 630 mm, and the fuel flow rate of approximately 30 l/min. Analysis covered flow velocity and pressure at selected points of the design. The tests were conducted for two cases. The first covered constant fuel flow from all injectors; the second covered dynamic states that take place when the injector is opened. The purpose of these tests was to check the possibility of using this solution for prototype purposes.
