FIELD: hydrodynamics and aerodynamics of vehicles moving at high speed.
SUBSTANCE: boundary layer of medium is acted upon by revolving magnetic field of modified induction motor built into vehicle body. Proposed method for reducing resistance to vehicle movement in space includes setting-up of magnetic field moving at constant speed by means of stator multiphase electromagnetic system on its external surface. Stator is disposed in front of vehicle and on its section creating highest resistance during its movement. Tops of stator teeth are aligned with external surface of vehicle, magnetic field is accelerated to desired speed, desired magnetic strength is set up in boundary layer of medium wherein vehicle is moving. Discharger is disposed in front of stator so that tops of its contacts come in contact with boundary layer of medium and electrical discharge occurs in direction transversal to vehicle movement. Discharger is positioned relative to stator so that desired clearance is provided between them and contacts are disposed opposite stator teeth. Voltage is applied to these teeth and discharger operation is synchronized with magnetic field movement. Electrical discharge is produced in boundary layer of medium to saturate the latter with free charges. Magnetic field moves charges and connected mass of medium away from vehicle surface thereby reducing boundary layer density and resistance to vehicle movement.
EFFECT: reduced power requirement.
