The landing gear, one of the larger components of the aircraft, serves to manoeuvre during take-off, landing and taxiing. In its supporting parts, the landing gear holds the entire weight of the aircraft with passengers and freight on the ground. This means it has to absorb and transfer all the dynamic forces, shock and stress into the ground, especially when landing.
For these enormous, volume-specific types of stress there are two materials which may be employed: super high-strength steels and titanium alloys, with the alloy proportion steadily increasing.
The landing gear consists of a variety of individual parts, which are machined with turning, drilling and milling operations: for example, this is how holes become incorporated and how pockets, dowel holes and location faces are produced.
