A Study of Rough-Terrain-Induced Structural Landing Loads. Phase III. Simulated Landings of an OV-1 Aircraft over Rough Terrain and Comparison of Experimental Loads with Theoretical Predictions

摘要

The report describes the third phase of a project directed toward the establishment of aircraft design criteria for rough terrain landing operations. The report presents the results of moving drop tests in which an OV-1 main landing gear was made to traverse simulated terrain irregularities of various sizes and shapes during landing impact. Test results for several cases are compared with the results of dynamic loads calculations performed on a digital computer. Recommendations for improvement of the analysis are made based on this comparison. (Author)
