Introduction to the problem of calculating the parameters of the mixing chamber of an afterburning bypass engine

The article considers the problem of calculation accuracy when using mathematical models gas-turbine engines second level complexity, example a device for mixing flows core engine and bypass duct gas turbine engine, suggests methods solving it. processes taking place in chambers air-breather are considered to be difficult modeling since exchange kinetic thermal energies characterized by different velocities, pressures, temperatures chemical composition occurs them simultaneously. mixer does not only ensure from ducts, but also acts as kind throttle. It regulates pressure downstream fan and, consequently, air consumption duct, thus affecting directly characteristics distribution over ducts. paper presents dependencies workflow parameters that allow more accurate verification complexity.
