METHOD OF CREATION OF LIFT FORCE

摘要

FIELD: mechanical engineering; designing of devices for creation of lift force of apparatus. SUBSTANCE: method consists in creation of lift force on surface placed in viscous fluid medium which consists in creation of difference in pressures acting on opposite sides of this surface through forming layer of particles of viscous fluid medium on part of this surface; particles move at some distance from this surface; then at least part of layer is turned in direction of surface; turn is effected through reduction of pressure in at least part of area bounded by layer on one side and by part of surface on other side. In realization of this method, part of layer may be formed by flow of viscous fluid medium around surface at simultaneous separation of least part of flow and injection of least one jet of viscous fluid medium at angle to surface. EFFECT: extended range of application and enhanced efficiency of method. 7 cl, 2 dwg
