How does an aircraft shock strut work?

Oleo struts absorb and dissipate shock loads using a combination of two fluids — a gas and a hydraulic fluid — contained in two chambers — a cylinder and a piston. As the aircraft touches down, the piston travels up into the cylinder, forcing hydraulic fluid through the orifice into the upper chamber.

What are the three types of landing gear struts?

Three basic arrangements of landing gear are used: tail wheel-type landing gear (also known as conventional gear), tandem landing gear, and tricycle-type landing gear.

What do you mean by struts?

Definition of strut (Entry 2 of 3) 1 : a structural piece designed to resist pressure in the direction of its length. 2 : a pompous step or walk. 3 : arrogant behavior : swagger.

Is a strut a shock?

The major difference between shocks and struts is that a strut is a structural part of the vehicles suspension system where a shock is not. A strut is also crucial part of the vehicles steering system and greatly affects alignment angles.

How do you service shock struts?

Release any air pressure in the shock strut. Remove the air service valve assembly. Fill the strut to the level of the service port with approved hydraulic fluid. Attach the bleed hose to the service port and insert the free end of the hose into a container of clean hydraulic fluid.

What are seaplane floats called?

A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. British usage is to call “floatplanes” “seaplanes” rather than use the term “seaplane” to refer to both floatplanes and flying boats.

What is strut in mechanical engineering?

A strut is a structural component commonly found in engineering, aeronautics, architecture and anatomy. Struts generally work by resisting longitudinal compression, but they may also serve in tension.

What is the difference between column and strut?

1) both column and Strut is comprehensive member but main difference between two is column is comprehensive member of frame structure and strut is comprehensive member of truss structure. but strut is subject to only axial force that is compressive force. …

Do I need struts or shocks?

As a general rule, it’s recommended you replace your shocks every 12,000 miles, and replace your struts every 50,000 miles. Some signs of failing shocks or struts include taking potholes and speed bumps especially hard, a front-end nose-dive when braking, and any signs of leaking hydraulic shock fluid.
