Oleo strut

An oleo strut is a pneumatic air–oil hydraulic shock absorber used on the landing gear of most large aircraft and many smaller ones. This design cushions the impacts of landing and damps out vertical oscillations.

It is undesirable for an airplane to bounce on landing - it could lead to a loss of control. The landing gear should not add to this tendency. A steel coil spring will store impact energy and then release it - the impact energy being the force of the airplane hitting the ground. An oleo strut absorbs this energy, reducing bounce.

As the strut compresses, the spring rate increases dramatically, because the air is being compressed, while the viscosity of the oil dampens the rebound movement

The largest cargo airplanes in the world, like the Antonov An-124 Ruslan, use oleo struts to allow for rough-field landing capacity with a payload of up to 150 tons. This design also cushions the airframe from the impacts of taxiing.

History

Oleo struts have been in use for many decades.Oleo-pneumatic shock absorber technology has continued to be refined, for example with US patent 2959410 A in 1960).

He grounds her after learning she skipped school, prompting Claire to be more outraged. Claire later shows up at Meredith's trailer, hoping that her biological father could help Mrs. Bennet. Meredith tells Claire that he will only disappoint her, and Meredith herself is going back to Mexico. She takes a picture of Claire as remembrance, which she later shows to a visiting Nathan.
