AUTOMATED CONTROL OVER SPACESHIP NATURAL OUTER ATMOSPHERE DUSTINESS AT HEAT-VACUUM TESTS AND CAPACITIVE ASPIRATION SYSTEM WITH CAPACITIVE ASPIRATION TRANSDUCERS TO THIS END Russian patent published in 2015 - IPC G01N7/10 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering. In compliance with claimed process, vacuum chamber degassing is started simultaneously with dusty air suction into chambers of capacitive aspiration transducers. Note here that dielectric constant and capacity of aspiration transducer input capacitors, resonance modes of oscillatory circuits connected thereto vary. Then, dusty air is filtered at appropriate filters and, then, forced to tail capacitors of transducers without varying the dielectric constant, capacity of tail capacitors, resonance modes of oscillatory circuits connected thereto. Data written by the instruments are analyzed to decide on purity of spaceship aspiration air. The capacitive aspiration system comprises identical capacitive aspiration transducers with porous filter and identical head and tail capacitors including two sets of blade plates shaped to Archimedes coil. One set of said plates is secured equidistantly at cylindrical plates of the capacitors. The other set of porous blade coatings also shaped to Archimedes coils is secured at aerodynamic coaxial cores. The latter are isolated from cylindrical coatings and arranged in the capacitor lengthwise axis.

EFFECT: higher reliability and sensitivity, continuous control over dustiness, higher quality of control, validity and accuracy.
