FIELD: jet facilities. SUBSTANCE: swirl tube is installed for turning around axis intersecting with axis of swirl tube at right angle to the latter by means of turning device. Longitudinal ribs are installed at both sides of swirl tube in diametral vertical plane. Ribs are made in form of wings with streamlined profiles, and tube has reservoir made in form of wing streamlined at side of approach air flow and arranged in the same plane as longitudinal ribs. One hole is made in end face of reservoir pointed towards approach air flow. This hole provides communication of inner space of reservoir with surrounding medium. Inner space of reservoir communicates with inlet hole of swirl tube. EFFECT: enlarged operating capabilities. 118 cl, 58 dwg
