What is the suspension of an airplane?

The suspension of an airplane refers to its landing gear system, which includes components like wheels, tires, struts, and shock absorbers. This system supports the aircraft during ground operations, absorbs landing impacts, and ensures stability while taxiing, taking off, and landing. Proper suspension is crucial for maintaining control and comfort for passengers and crew during these phases. Additionally, it helps protect the airframe from damage caused by runway irregularities and landing forces.
