Drach O. Magnetic gas dynamics influence on the inlet duct flow parameters of the aviation power plant

Mathematical flow calculation methods for cylindrical channels with and without central body under and without electro-magnetic forces influence have been designed and adapted. Radial nonuniformity influence existence on the turbofan (turboprop) engine inlet duct effectiveness have been analyzed and established. Methods of sufficient partial ionization for electromagnetic and electrostatic flow control at standard atmospheric conditions in cylindrical channel with or without central body were designed. Recommendations on inlet duct effectiveness increase by electromagnetic and electrostatic flow control means were given. Approbation results of the designed method were represented. The designed method allows to decrease the value of radial nonuniformity to the acceptable level - 17-18%, that doesn't influence significantly on the compressor gas dynamic stability.
