Abstract
Система регулирования давления воздуха в гермокабине летательного аппарата, содержащая командный прибор, ко входам которого подключены задатчики давления, датчики атмосферного и кабинного давления и датчик скорости изменения давления в гермокабине, а выход связан с исполнительным устройством, состоящим из последовательно соединенных усилителя мощности, электропневмопреобразователя и выпускного клапана, резервный регулятор давления, связанный с выпускным клапаном исполнительного устройства через повторительное устройство, в атмосферную линию которого включен ограничитель минимального давления через нормально открытый клапан соленоида, бортовой вакуумнасос, включенный в линию сброса электропневмопреобразователя и переключающее устройство, отличающееся тем, что, с целью повышения надежности системы и сокращения времени предполетного контроля, в ней переключающее устройство включено в атмосферную линию резервного регулятора давления, причем нормально открытый канал переключающего устройства связан с атмосферой, а нормально закрытый канал - с линией сброса электропневмопреобразователя, к которой подключен и нормально закрытый канал соленоида.Air pressure control system in the aircraft cabin pressurized cabin, containing a command device, pressure inputs, atmospheric and cabin pressure sensors and pressure change sensors in the pressure cabin are connected to the inputs, and the output is connected to an actuator consisting of a series-connected power amplifier, electropneumatic transducer and outlet valve, backup pressure regulator connected to the exhaust valve of the actuator through the repeater device in the atmosphere The ferronic line of which includes a minimum pressure limiter through a normally open solenoid valve, an onboard vacuum pump included in the discharge line of an electropneumatic transducer and a switching device, characterized in that, in order to increase the system reliability and reduce the time of pre-flight control, the switching device is included in the atmospheric backup pressure regulator, and the normally open channel of the switching device is connected to the atmosphere, and the normally closed channel is connected to the discharge line ektropnevmopreobrazovatelya, to which it is connected and the normally closed solenoid channel.
