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. %8 2018-04-04
