A system for reducing a temperature of a braking assembly (320) includes the braking assembly of a wheel assembly, an airflow amplifier (310), and a conduit (305). The braking assembly includes a plurality of friction disks. The airflow amplifier (310) is coupled to the wheel assembly, and the conduit (305) extends from a compressed gas source (301) to the airflow amplifier (310). Generally, the airflow amplifier is configured to entrain ambient air ("entrained air") in response to compressed gas from the compressed gas source flowing to the airflow amplifier (310) via the conduit (305). The airflow amplifier (310) is configured to direct the entrained air and the compressed gas to the braking assembly (320) to reduce the temperature of the braking assembly.
