Abstract
The modern concept of brake disc development provides for two main tasks: ease of manufacture and efficiency of operation with minimal economic costs. As a rule, both of these tasks are incompatible and have different goals. The operating principle of all ventilation devices of brake discs is the same, heat removal by passing cooled air through the channels. However, the efficiency of this physical process varies depending on the design of the disk. The influence of the opening angle of diffuser-type ventilation channels on the efficiency of the brake disc ventilation device is considered. The study presents a comparative characteristic of various, most common designs of ventilation apparatus, and a new method for solving the tasks is proposed.
