Abstract : An experimental investigation was performed of the dynamic response characteristics of the Princeton 20-foot annular jet Ground Effect Machine and the U. S. Army Transportation Research Command 15-foot 'Hula-Hoop.' The tests ranged from dynamic stability and control responses to performance and for the P-GEM also the operation over specially prepared test tracks simulating various conditions of rough terrain. The P-GEM successfully negotiated all prepared obstacles. The calculated values of frequency and damping ratio from existing two-dimensional theories are found to be inadequate for the prediction of the dynamic characteristics of the test vehicles.
