摘要
FIELD: transportation, aviation.;SUBSTANCE: aircraft model to study impact of jet stream at aerodynamic characteristics of the aircraft includes a thin-walled body fixed on a side holder with an aft nozzle and drainage holes along outer surface, drainage tubes laid in the side holder and connected to a pressure registration device, a compressed air supply system towards a model nozzle comprising a compressed air balloon, air ducts laid in the side holder and an internal cavity of the model. There are cavities arranged in the walls of the model body for placement of drainage tubes, covered by shells at the outer side and following the external contours of the model body. Drainage tubes stretch from the side holder of the model inside the arranged cavities and are joined with side channels in the body of main part of the model body. Channels are made from the side of cavities formed in the body until crossing with the external drainage holes perceiving the static pressure.;EFFECT: invention is aimed at increased validity of pressure distribution measurement results.;3 dwg
