Full-scale dynamic landing-impact investigation of a prototype lunar module landing gear

In order to subject prototype components of a lunar-module (LM) landing gear to some of the dynamic loads of lunar-landing impact, full-scale tests were conducted at simulated lunar gravity.The full-scale tests were conducted with a planar (three degrees of freedom) lunar-gravity simulator and a full-scale test vehicle.a prototype landing-gear system (struts and deployment trusses) was substantiated.Dynamic performance of the landing-gear struts was good for all landing conditions tested including those which produced near maximum strokes and loads.results were in agreement with experimental results obtained for landing accelerations, gear forces and strokes, and vehicle pitch motions.Structural integrity of Theoretical Flat Flat Flat Flat Flat Elevation at g e a r s 1 and 4 Elevation at g e a r s 1 and 4 Elevation a t gear 4 ~ ~~ Flat Elevation a t gear 4 Elevation at gear 4 Elevation at gear 4 Elevation a t gear 4 Elevation at gear 4 ~_ _ Elevation at gear 4 Elevation at g e a r s 2 and 4 Elevation at g e a r s 2 and 4 Flat Flat Elevation at g e a r s 1 and 4 Elevation
