Abstract
FIELD: mechanical engineering; manufacture of wings; main rotors and compressor and turbine blades for reduction of resistance of streamlined surfaces. SUBSTANCE: lifting surface has vortex generators made in form of fences located across the incoming flow and partitions mounted in vortex generators over entire length of fence in parallel relative to each other in way of flow; in the bottom portion of vortex generators there are through slotted holes brought out to streamlined surface. When lifting surface is washed with liquid or gas, area of reduced pressure with bound vortex is created in bottom portion of vortex generator. Due to bottom rarefaction, part of flow passes from boundary layer on streamlined surface to vortex generator through slotted holes preventing flow from being separated and enters the flow on lifting surface in directed jet. Innovation of invention consists in control of boundary layer on streamlined surface through slotted holes making use of local areas at reduced pressure on streamlined surface. EFFECT: reduced resistance due to control of boundary layer on streamlined surface.
