Auxiliary Power Unit (APU)

The APU was developed for the RoKN (Republic of Korea Navy). It is a small-sized, 400 Hz, gas turbine generator with a 60 kW capacity. The APU produces bleed air to start a craft’s propulsion/support gas turbine and produces electric power as a generator. Since multiple motors and turbines are normally needed to do these tasks, utilizing the APU allows for more lightweight warships.
