MEASUREMENT OF THE PARAMETERS OF THE AMBIENT AND RAM AIR STREAMS ON AIRCRAFT Russian patent published in 2023 - IPC G01L7/00 

FIELD: instrumentation.

SUBSTANCE: device contains a housing, which has two openings communicating with the measured medium, and inside which there is an aneroid sensitive element formed by the upper and lower membranes, which are tightly attached to the housing with formation of an airless gap between them. In this case, two openings of the housing are located respectively above and below the gap, one radiation source and one optical ruler are installed, rigidly attached to the side wall of the housing. In addition, shutters with slots of a certain shape are installed in the geometric centres of the upper and lower membranes with an offset relative to each other, and the geometric centres of the study source, the optical ruler and the slots of the shutters are located on the same axis.

EFFECT: invention can be used to measure the height and speed of aircraft, as well as angles of attack, based on the use of the aerometric method
