Safety Design and Test Verification of Uncontained Fragment Event for Aeroengine

The aeroengine uncontained high-energy fragment is a failure event with hazardous effects that is unanimously recognized by national standards and airworthiness regulations. This paper starts from the perspective of aeroengine uncontained high-energy fragment incident, summarizes the relevant regulatory requirements for the incident, analyzes the safety design of the aeroengine in response to the incident, and summarizes the test method for the incident. The reference for safety design analysis and experimental verification research of other hazardous events is provided.
