FIELD: experimental aerodynamics.
SUBSTANCE: aerodynamic assembly tube can be used for production of low turbulence air flux when making on-ground tests of aviation technology objects. Device has rehabber provided with members for improve of quality of flux, collector-nozzle, drainage system, working part and heaters. According to first version, assembly has two steps of compression of flux in collection; steps are separated by intermediate department provided with drainage-suck out system for part of flux, and heater for wall of department, which heaters are disposed along perimeter of department from outside aerodynamic circuit. According to second version, second compression step turns to working part directly after critical cross-section. Tube is additionally equipped with supports and check aids to keep its vertical position. Laminar boundary layer demonstrates higher stability and helps pulling laminar-turbulent transition.
EFFECT: reduced level of turbulence inside flux.
