The Application of Forgings in Aviation Aircraft

Forging technology has a wide range of applications in the aviation industry, mainly used in the manufacture of aircraft to withstand alternating load and concentrated load of key parts. Such as for the manufacture of aircraft fuselage structure, engine rotation parts and landing gear and other main bearing parts.The quality of parts made of forgings accounts for 20% ~ 35% of the total weight of aircraft body structure and 30% ~ 45% of the total weight of engine structure. It is one of the important factors that determine the performance, reliability, life and economy of aircraft and engine.

Application of forgings to aircraft fuselage structure

Forgings are widely used in aircraft fuselage, such as engine frame, door frame, fuselage bearing frame beam, wing frame beam, joint and other parts. Among them, the fuselage bearing frame beam, wing frame beam, joint and other parts are mainly produced by die forging, and the materials are mainly titanium alloy, aluminum alloy and structural steel. At present, the characteristics of aircraft fuselage structure forgings are: complex structure, large projection area, forming difficulty; In recent years, more and more new materials have been used, and the requirements for their structure, fracture toughness and fatigue strength are increasing.

Application of forgings to the landing gear

Landing gear is a vital part of both military and civilian aircraft. In the process of frequent takeoff and landing, the landing gear of the aircraft has to bear large impact load. Therefore, the requirements for the structure and performance of forgings are higher, and the metallurgical process and forging process of structural materials need to be strictly controlled.

Material with high strength structural steel and high strength and high toughness titanium alloy, deformation resistance in the process of processing. It has high requirements on the uniformity, impact resistance and fatigue resistance of forgings.
