The Oleo Strut was a coffeehouse in Killeen, Texas, from 1968 to 1972. Like its namesake, a shock absorber in helicopter landing gear, the Oleo Strut’s purpose was to help GIs land softly. Upon returning from Vietnam to Fort Hood, shell-shocked soldiers found solace amongst the Strut’s regulars, mostly fellow soldiers and a few civilian sympathizers. But it did not take long before shell shock turned into anger, and that anger into action. The GIs turned the Oleo Strut into one of Texas’s anti-war headquarters, publishing an underground anti-war newspaper, organizing boycotts, setting up a legal office, and leading peace marches.
The GI anti-war press was everywhere and just about every base in the world had an underground paper. Vietnam GI was the first GI paper. It was sent directly to Vietnam from the U.S. in press runs of 5,000 and they were getting spread all over the place because they would be handed from person to person. Awareness of the GI Movement was at different levels but it was still very widespread.
That was where the coffeehouse came in. The GIs did the work, for the most part, off base. At the Oleo Strut there was an office that they worked in that had a printer who would do printing for the soldiers.
Some papers would get mimeographed secretly on the military bases because the individuals working on them would be clerks that had access to the proper resources. Soldiers would hand them out off base but they would also be distributed on base. Some soldiers would go into a barracks and put them on beds and foot lockers.
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.
Usage examples of "oleo strut".
The landing lock was going to fold on the fulcrum and the oleo strut was going to swing up and bring the wheels with it, their huge tyres spinning and their weight forced into the bay by the hydraulics, slamming home as the doors came together below.
