Abstract
According to an aspect, a system for a gas turbine engine includes a reduction gear train operable to drive rotation of a starter gear train that interfaces to an accessory gearbox of the gas turbine engine. The reduction gear train includes a starter interface gear that engages the starter gear train and a core-turning clutch operably connected to the starter interface gear. The reduction gear train also includes a planetary gear system operably connected to the core-turning clutch and a jacking gear system operably connected to the planetary gear system and a core-turning input.
