The thesis is devoted to increasing energetic efficiency of the conveyors on an air cushion with inclined round channels by the improvement of their construction parameters, such as : angle of inclination, diameter and relative square of channels. In thesis the mathematical models of lift force coefficient, traction force coefficient, consumption coefficient and aerodynamic factor of the conveyor on an air cushion with inclined round channels are obtained and experimentally tested. Using the obtained mathematical models, functional dependence between construction parameters of the conveyor on an air cushion with inclined round channels and its energetic efficiency is stated. Based on the stated dependence between construction parameters and energetic efficiency of the conveyor on an air cushion with inclined round channel, the energy-efficient angle of inclination, diameter and relative square of channels are determined. According to the results of lead researches, account technique of the conveyors on an air cushion with inclined round channels is created. The application of this technique allows to receive the highest energetic efficiency of conveyor. Keywords : conveyor, air cushion, lift force coefficient, traction force coefficient, consumption coefficient, energetic efficiency.
