Why is it called oleo strut?
History and applications Vickers’ oleo strut was first applied to an aeroplane by the French aircraft company Breguet Aviation. The design proved to be viable and was extensively adopted across the aviation industry for fixed undercarriages, becoming simply referred to as an “Oleo unit” or undercarriage leg.
What is oleo strut in landing gear?
a hydraulic device used as a shock absorber in the landing gear of aircraft, consisting of an oil-filled cylinder fitted with a hollow, perforated piston into which oil is slowly forced when a compressive force is applied to the landing gear, as in a landing.
What is an aircraft oleo strut?
The oleo strut is an increasingly reliable aircraft component used on the aircraft landing gear that can withstand tremendous loads and has a relatively more straightforward design. It utilizes hydraulic fluid and air pressure to create a spring effect.
What type of oil is used in an oleo strut?
The main structure of the oleo strut consists of a piston that’s attached to the wheel and a cylinder that’s attached to the airframe. Inside the tubes are what’s generally referred to as oil, but usually is hydraulic fluid, and compressed air or nitrogen.

How much hydraulic fluid should be put into an oleo strut?
around a gallon
Typically it takes around a gallon of hydraulic fluid to service three struts. Nitrogen is better than compressed air for strut servicing because it is drier and doesn’t vary in pressure as much as air; it is also less corrosive to the inside of the strut housing.
How does an oleo strut dampen the shock of landing?
By converting a portion of the aircraft’s kinetic energy to heat, oleo struts absorb and dissipate forces associated with landing.
Is oleo still made?
“Oleo” is another word for margarine (or oleomargarine). Nothing more, nothing less. It’s still used today, but it’s not as common as it once was.
Why is both fluid and air used in the design of an air oil oleo strut?
Shock struts, often called oleo or air/oil struts, use a combination of nitrogen (or sometimes compressed air) and hydraulic fluid to absorb and dissipate shock loads on landing.

Can a 747 take-off with 3 engines?
The 747 is certified to fly on just three engines, and there was no indication of any damage to the aircraft’s other engines. Safety experts and aviation regulators still questioned the decision to operate such a long flight with one engine out.
