Aviation forgings play an important role in the aircraft structure, mainly in the following aspects: bearing and transferring load: Aviation forgings are usually used to withstand a variety of forces and loads from the aircraft, such as the aerodynamic force generated during flight, ground operation and the impact force during take-off and landing, engine thrust and so on. These forgings, through their strength and stiffness characteristics, transfer the load from one desired structural part to another and guarantee the safety and stability of the entire aircraft structure. Connection and support: Aviation forgings, as connectors or support parts, realize the connection and support function between different parts and systems. For example, the use of large forgings as connectors at the joint of the aircraft wing and fuselage ensures a tight connection between the wing and fuselage; Forgings are used as support components on the main landing gear to withstand huge loads during takeoff and landing. Fatigue resistance and durability: Aviation forgings require excellent fatigue resistance and durability, as they are subjected to reciprocating loads and vibrations during long-term use. Through reasonable design, high-quality materials and advanced processing technology, aviation forgings can withstand the action of high load stress for a long time and continue to crack or fail. Weight saving: The weight control of the aircraft structure in the aviation industry is very important, and the aviation forgings can achieve effective weight saving because of their high specific strength and high material utilization. Avoid the use of too many connectors and reinforcing structures, through the rational application of forging process, so that the forging can bear the load while reducing the overall structural weight as much as possible. In general, aviation forgings play an important role in supporting, transferring and connecting loads in aircraft structures, and have the characteristics of fatigue resistance and weight saving. They play an irreplaceable role in ensuring the safety, reliability and economy of aircraft.
