Investigation of the Air-compression Process During Drop Tests of an Oleo-pneumatic Landing Gear
This is a 1951 NASA technical report, published in the United States for aeronautical engineers, on drop tests of an aircraft oleo-pneumatic landing gear. The pictures are mostly instrument traces and photographs of the test gear, showing how the strut's air compression and load were measured. A designer might take from them the clean line-chart style of stacked oscilloscope-like traces and the labelled engineering photograph of a wheel and strut with callouts.
