generator after the engine has reached a self-sustaining speed. This saves weight and space on the engine. The starter generator is permanently engaged with the engine shaft through the necessary drive gears, while the direct cranking starter must employ ... some means of disengaging the starter from the shaft after the engine has started. The starter generator unit is basically a shunt generator with an additional heavy series winding. [Figure 5-16] This series winding is electrically connected to produce…

power demands required to turn the large turbofan engines during the starting cycle on transport aircraft. Electric Starting Systems & Starter Generator Starting System Electric starting systems for gas turbine aircraft are of two general types: direct cranking electrical systems ... starter generator systems. Direct cranking electric starting systems are used mostly on small turbine engines, such as Auxiliary Power Units (APUs), and some small turboshaft engines. Many gas turbine aircraft are equipped with starter generator systems. Starter generator starting systems…
