AEROMETRIC PRESSURE SENSOR Russian patent published in 2019 - IPC G01L7/08 G01L11/02 

FIELD: measuring equipment.

SUBSTANCE: device relates to an instrumentation technique and can be used to measure the height and speed of flight of aircraft based on the use of the aerometric method. Device comprises a housing with two openings, two main membranes, tightly attached along the perimeter to the housing and forming a gap by spacing in height, the holes communicating with the measured medium are placed above and below the gap, mounted on the rack a radiation source and, in addition, the upper and lower curtains with slots. Device also contains two photodetector bars, with the geometric centers of the upper and lower main membranes containing openings that are blocked on the outer sides of the membranes with respect to the gap by additional upper and lower membranes, tightly attached along the perimeter to the outer sides of the main membranes, with the photo-receiving lines attached to the upper and lower additional membranes respectively and facing the slots of the upper and lower curtains.

EFFECT: increasing the sensitivity and accuracy of pressure measurement both in altitude and in flight speed of the aircraft.
