ABSTRACT

A numerical simulation method of the flow in complex (branched and multi-component) pneumatic lines used in contemporary aircraft is presented. The method is based on integrating the crosssectional averaged Navier–Stokes equation and applying empirical data to the hydrodynamic losses in various elements of pneumatic lines. A comparison of the results of the calculations and experimental studies of real pneumatic lines of a maneuverable aircraft is given, and good agreement is shown.
