What special factors should be considered in the design and manufacture of aircraft forgings?
The design and manufacture of aircraft forgings need to consider the following special factors: Strength and stiffness requirements: Aircraft forgings need to meet the requirements of high strength and stiffness to withstand the huge loads and vibrations faced in flight. Factors such as material selection, section shape and size need to be taken into account in the design to achieve the required strength and stiffness. Safety and reliability: Aircraft forgings must have a high degree of safety and reliability during use to cope with various extreme conditions. Factors such as fatigue life, fracture toughness and corrosion resistance of the material need to be taken into account in the design to ensure that the forgings remain safe and reliable under various conditions. Weight and space constraints: The aircraft is a weight-sensitive vehicle, and every part needs to meet strength and function requirements while being as light as possible. In the design, the structural shape and material need to be reasonably optimized to reduce the weight of the forgings and meet the space constraints of the aircraft. High temperature and heat resistance: Aircraft will face high temperature environments during operation, such as forgings in the engine exhaust system need to have high temperature resistance. In the design, it is necessary to choose the appropriate material and heat treatment process to improve the high temperature strength, creep resistance and heat fatigue life of the forgings. Manufacturing feasibility: The manufacturing of aircraft forgings needs to take into account the malleability, complexity and machining difficulty of the shape of the forgings. The feasibility of forging process, subsequent processing process and equipment need to be reasonably considered in the design to ensure that the forging can be effectively realized in the manufacturing process. 6. Inspection and quality control: Aircraft forgings need to undergo strict non-destructive testing and quality control to ensure that there are no defects in the production process and meet the design requirements. The feasibility and applicability of various non-destructive testing technologies should be taken into account in the design, as well as the reasonable setting of quality control points and standards. In short, in the design and manufacture of aircraft forgings, it is necessary to consider various factors such as strength, stiffness, safety, reliability, weight, space constraints, high temperature performance, manufacturing feasibility, testing and quality control to ensure that the forgings can meet the high requirements of performance and reliability in the use of aircraft.
