METHOD AND SYSTEM FOR CONTROL OF AIR PRESSURE IN FLYING VEHICLE Russian patent published in 2004 - IPC

FIELD: devices for automatic check of air pressure in ventilated pressurized rooms of flying vehicle.

SUBSTANCE: proposed method includes optimization of air pressure in ventilated pressurized rooms of flying vehicle by action on air supply regulator of outlet valve. Power signal to electric drive of regulator is formed by respective mismatch of preset and real magnitudes and rate of change of absolute pressure in these rooms. To this end, use is made of electronic computer unit equipped with software for realization of algorithm of forming power signal control commands. Power signal is formed in accordance with required position of working member of outlet valve. Magnitude of signal is calculated as sum of products of respective constants by mismatch of absolute and excessive pressures and first and second derivatives of absolute pressure in time with product of time integral of this sum by respective constant. Power signal is formed in accordance with characteristic of position of working member of outlet valve versus power signal and absolute pressure in ventilated room and atmospheric pressure on the outside of flying vehicle.

EFFECT: improved automatic control.
