SYSTEM FOR DETERMINING AIR FLOW PARAMETERS Russian patent published in 2011 - IPC G01P5/16 

FIELD: instrument making.

SUBSTANCE: system for determining air flow parameters includes in-series connected multi-channel receiver of air signals, which is made in the form of rotation body and includes air flow parameters determining unit, two screening discs and atmospheric parameters determining unit. In screening discs there are cavities of local static pressure, which contain receiving holes of local static pressure and are located in circumferential direction of discs. Atmospheric parameters determining unit includes compressed-air electric static pressure converter, thermal electrical measuring schemes, analogue-to-digital converter and computing device. Multi-channel receiver of air signals includes additional unit for determining air flow parameters, which includes primary information sensors. Atmospheric parameters determining unit is made in the form of chamber with air-permeable walls, inside which temperature sensor is installed.

EFFECT: improving operating safety of helicopters and operating reliability of system.
