Synchrophasing for sound control in airplane, defined as control of each propeller in unique position with respect to aircraft structure; besides holding identical speeds of all propellers, blade relationship remains fixed within limits when under phase control; it is claimed that synchrophasing distinctly lowers sound level in cabin; psychological aspects.
