Aircraft forgings are an important part of the aircraft manufacturing process. If there are problems with their quality and performance, they can seriously affect the safety of the entire aircraft. The following is a detailed analysis of this issue using an example from actual production.
In September 2018, a Boeing 737 passenger plane crashed during takeoff in Kazan, Russia, killing 55 people. The investigation showed that the accident was related to the quality of the aircraft component forgings.
According to reports, before this accident occurred, the aircraft had been maintained and some parts had been replaced, including the turbine fan forging. However, due to the company’s insufficient experience in forging production, a low-quality metal material was used, which caused problems with the performance of the turbine fan forging, ultimately leading to the accident.
This case shows that if there are problems with the quality and performance of aircraft forgings, they can seriously affect the safety of the entire aircraft. Therefore, during the production process, measures must be taken to ensure that the quality and performance of the forgings meet relevant standards and regulations, in order to improve the safety and reliability of the aircraft.
Strict control measures are necessary during the production process to ensure the quality and performance of forgings. Firstly, high-quality materials must be chosen to ensure the strength and toughness of the forgings. Secondly, during the forging process, suitable forging methods and process parameters should be chosen according to the shape, structure, and functional characteristics of the forgings. Fine control should be exercised over the heating, forging pressing, and other operations to ensure that the structure and performance of the forgings meet the required standards. Finally, the forgings should undergo inspections, including physical property testing, defect detection, and dimensional inspection, to ensure that their quality meets relevant standards and regulations.
In conclusion, insufficient experience in the production of aircraft forgings can seriously affect the overall performance of the aircraft. Therefore, during aircraft manufacturing, the quality and performance of forgings must be strictly controlled to improve safety and reliability.
