- Abstract
- Safe issue is the most important consideration in the transport aviation activity. As the powerplant of civil aircraft, the operational safety of aero engine is pursued as the upmost target by each engine manufacturer. Prior to the final delivery, the engine is required to go through series of rigorous rig tests such as vibration, overspeed, bird and hail ingestion, and blade containment to demonstrate its safety margin to the relevant authoritative rules under different critical operating conditions, which is well known as the airworthiness certification procedure. Only the products passing through all the proof tests successfully can be approved to enter into service. Based on a typical aero engine, this paper aims to elaborate the primary test demonstrations in the safety verification process, and introduce the feasible approaches to meet the stringent requirements of world-popularized engine certification standards: FAR Part 33. Although there are still some optional methods to show the compliance with applicable rules, the illustrations presented here can be treated as the helpful guideline for the engine manufacturers to prepare for the final engine safety demonstration.
