flygplansfjädring

Flygplansfjädring, commonly referred to as aircraft suspension, is a critical system that absorbs landing impact and absorbs turbulence during flight. Unlike the suspension systems found in automobiles, aircraft suspension is primarily designed to handle immense vertical forces and energy dissipation upon touchdown. The most common type of aircraft suspension is the oleo-pneumatic strut, which utilizes a combination of hydraulic fluid and compressed air or nitrogen.

During landing, the oleo-pneumatic strut compresses, forcing hydraulic fluid through a small orifice. This process converts the kinetic energy of the aircraft into heat, effectively damping the shock. As the strut extends after impact, the compressed gas absorbs any remaining energy and returns the strut to its normal length, preparing the aircraft for taxiing. The design of these struts is crucial for ensuring passenger comfort and protecting the airframe from excessive stress.

Aircraft suspension is typically located within the landing gear assembly, connecting the wheels to the aircraft's fuselage or wings. The specific design and complexity of the suspension vary greatly depending on the size, weight, and intended use of the aircraft. Smaller general aviation aircraft may have simpler spring-based systems, while large commercial airliners employ sophisticated oleo-pneumatic struts capable of absorbing significant landing loads. Regular maintenance and inspection of the suspension system are essential for safe aircraft operation.
