Research on Reliability Integration Test Method for Civil Aircraft Airborne Systems Based on Fault Injection

Reliability integration test is a kind of system integration tests which conducted on test benches such as iron bird to verify the safety and reliability design of civil aircraft airborne systems. It is necessary to inject faults into the tested airborne system through a fault injection system when conducting reliability integration test. By observing the status of the tested system and the changes in detection signals after injection of faults, and evaluating the impact of faults to verify the safety and reliability design of the airborne system. This paper studies the reliability integration test and fault injection technology of airborne systems, proposes a testing system and process for reliability integration testing based on fault injection. Through application cases, the operational methods and implementation effectiveness of the testing system and process were demonstrated.
