FIELD: measuring technique, possibly measuring parameters of gaseous medium flows or determining movement parameters of transport vehicles such as airplanes, missiles and others relative to air environment. SUBSTANCE: receptacle includes body restricted by means of portion of lateral surface of round cone with apex angle no more than 20 degrees having central and peripheral receiving openings designed for determining direction and speed value of gas flow and by means of secant plane parallel relative to axis of round cone and having opening for determining Mach number and static pressure. EFFECT: enhanced accuracy of measuring static pressure and Mach number in flows of gaseous media moving at subsonic, transonic and supersonic velocities, lowered disturbances caused by receptacle in gas flow. 3 dwg |
