To evaluate the efficiency of the system of forced cooling of disc-pad brake mechanisms, the temperature on the working surfaces of the brake disc is proposed as a criterion. The parameters of influence on the forced cooling system include the pressure at the inlet of the ventilation unit, the angle of attack of the air flow, the number of air supply sources and the geometry of the ventilation unit. As a result of multifactorial experiments, the regression equations of temperature on the working surfaces of the brake disc were obtained from the above-mentioned influence parameters. The obtained data can be used in two directions: designing systems for forced cooling of brake mechanisms and controlling the thermal load of the brake disc.
