FIELD: aircraft engineering.
SUBSTANCE: passenger aircraft neutral gas system comprises the subsystems of neutral gas generation, neutral gas distribution and control. The neutral gas generation system comprises a shutoff valve, an air fine filter, an ozone converter, a two-way release valve, the main check valve, a pressure gauge, an oxygen analyser and two temperature gauges. The control system comprises the main and redundant units of a computer-concentrator with built-in diagnostics and control means, the main and redundant signal conversion units with built-in diagnostics and control means, a protection and switchover unit with built-in diagnostics and control means and an ARINC 825-standard redundant communication line.
EFFECT: higher reliability of the neutral gas system and flight safety.
