METHOD OF ADAPTING WORKING SECTION OF WIND TUNNEL TO PRODUCE NONINDUCTIVE AIRFLOW ON AIRCRAFT MODEL AND DEVICE TO THIS END

摘要

FIELD: transport.;SUBSTANCE: proposed method incorporated new technology of producing velocity components at airflow boundaries that correspond to unlimited airflow at tested model. Said technology is based on using inclined bores, valves and surfaces in the wall that allow bleeding pressure chamber air from the flow and forcing it therein in counterflow to acting local static pressure difference which is required at separate sections of current lines at unlimited airflow. Invention covers also the device to implement above said method.;EFFECT: adapting wind tunnel to noninductive airflow.;2 cl, 7 dwg
