Early results of study to establish procedures for predicting tumbling histories for vehicle that impacts on nonlevel surface; symmetrical and asymmetrical inelastic impacts are discussed; under symmetrical case main points of simple theory are restated, critical modes of overturning for 4-legged body are identified, computed and experimental landing stability boundaries for 4-legged rigid model are correlated, and computed boundaries for 2 rigid configurations representative of lunar landing vehicles are compared; it is found that asymmetrical approaches can be more critical than symmetrical approaches.
