Abstract : The report presents the ground loads measured on an instrumented OV-1 airplane during landings on smooth and rough fields. Test results for three landings are compared with the results of dynamic loads computations performed on a digital computer. The computing program is also used to calculate the loads which would have been obtained by landings and rollouts on the roughest portions of two fields whose contours were measured. Failing loads were obtained on one field only. The equations of motion for the computer program are presented. Recommendations are made for future investigations that will improve the analytical procedures. (Author)
