The KRET concern has developed a new integrated control system for the import-substituted Superjet aircraft. The project is currently in the final stages of certification. Over the past three years, 500 units have undergone 1,500 reliability tests to ensure performance under diverse operational conditions.
Engineers implemented a quadruple redundancy architecture to maintain flight control even if individual components fail. According to Rostec, the system demonstrates a reliability rate of one failure per billion operations. The electronics are designed to function within a standard range of -40 to 70 degrees Celsius.
During stress testing, the equipment was subjected to temperatures ranging from -55 to 85 degrees Celsius, including simulated fire conditions. The system also withstood voltage pulses of up to 1,500 volts, mimicking lightning strikes. Additional tests covered resistance to vibration, icing, salt fog, and dust.
The development involved 11 KRET enterprises, which produce approximately 650 distinct components for the aircraft as part of the import substitution program. Finalizing the certification of this control system marks a critical milestone in preparing the domestic airliner for active service.
