• According to the experiments on the bursting of the rotor with a rim, a boss, and blades, there are two modes in the bursting of the rotor depending on the magnitude of a boss. For instance, when the thickness of a boss varies widely and its diameter is constant, the bursting of the rotor occurs as follows ; - (i) The rotor bursts in the diametral section until the boss thickness reaches a certain value, and the bursting speed increases as the thickness increases in this range. (ii) The rotor bursts in the section around a boss and the bursting speed keeps a constant value when the boss thickness increases over this value. Therefore, the certain value is considered to be the critical thickness of a boss, and it is meaningless to increase the thickness of a boss over this critical value. These experimental data on the bursting of the rotor are accounted for considering individual effects of a rim, a boss, and blades on the bursting strength of a uniformly thick disc, and the practical dimensions on the critical thickness of a boss can be suggested.
