MEASUREMENT SYSTEM OF AIRBORNE VEHICLE ALTITUDE AND SPEED PARAMETERS Russian patent published in 2013 - IPC G01P5/00 

FIELD: instrument making.

SUBSTANCE: measurement system of airborne vehicle altitude and speed parameters includes an air pressure receiver, in the flow passage of which receiving openings as to full pressure of the receiver are marked, a generator and recording elements of an ion-marking channel, a pneumatic module of an aerometric channel, a primary informative signal formation unit and an output signal processing unit. In addition, the receiver is provided with a capillary pressure divider, and the flow passage is provided with throttled pressure receiving openings interconnected with the first input of capillary pressure divider, the second input of which is interconnected with full pressure receiving openings of air pressures receiver, which are interconnected by means of pneumatic channels with an aerometric channel pneumatic module. Further, a pneumatic module of barometric channel, the pneumatic input of which is interconnected with capillary pressure divider output, and a self-correction unit and an electric pneumatic valve, are introduced.

EFFECT: improving measurement accuracy and reliability, providing the possibility of continuous monitoring of the operating mode of measurement channels and adaptation of measurement channels to the change of flight conditions.
