METHOD OF CONTROL OF AIR PRESSURE IN PRESSURIZED COMPARTMENTS AND PRESSURE CONTROL SYSTEM FOR REALIZATION OF THIS METHOD Russian patent published in 2003 - IPC

FIELD: life support systems; rocketry and space engineering; launching systems. SUBSTANCE: proposed method includes delivery of air from atmosphere to compartments. By the moment of launch and during launch, conditioned air is additionally fed to compartments from individual pressure source. Optimal excessive pressure of 30-70 Pa is maintained in compartments. Proposed system is equipped with plenum-exhaust ventilation with compressed conditioned air bottles, flight director, exhaust valve in form of pneumatic damper, pressure indicator and normally closed electropneumatic valve. Bottles are communicated with pneumatic damper through gas reducer and electropneumatic valve. Pressure indicator furnishes signal to flight director when excessive pressure drops below 30 Pa or rise above 70 Pa. EFFECT: enhanced safety of personnel attending launch complex. 3 cl, 2 dwg
