MEASURING DEVICE OF PARAMETERS OF AMBIENT AND INCOMING AIR FLOWS ON AIRCRAFT Russian patent published in 2024 - IPC G01L7/08 G01L11/02 

FIELD: measuring.

SUBSTANCE: invention relates to devices of measuring equipment and can be used to determine parameters of ambient and incoming air flows acting on an aircraft – static, as well as full pressure or angle of attack. Device comprises a housing, the inner volume of which is through cavities communicating with the measured medium by means of holes in the housing, it includes a closed cavity with a radiation source and optical lines attached to the generatrix of its inner surface, so that light flux from the radiation source can pass through slots in the shutters attached to the corresponding elastic sensitive elements to the active surfaces of the optical lines. In the design of the measuring device, the upper and lower aneroid boxes are introduced as elastic sensitive elements, having a hole in one of the rigid centres, wherein said closed cavity is composed of top and bottom rigid plates spaced apart in height and shaped to housing hole and provided with holes at their geometrical centres. Upper and lower introduced aneroid boxes are tightly attached along the perimeter of rigid centres, having holes, are attached to external, with respect to the gap, sides of rigid plates, wherein openings of rigid plates and aneroid boxes are aligned while shutters with slots are secured to inner sides of rigid centres of upper and lower aneroid boxes, respectively.

EFFECT: expanding the range of measured air pressures, as well as ensuring equal sensitivity of the meter to the height of atmospheric pressure.
