  provide almost sparkless commutation from no load to full load. Figure 5-18 illustrates the external circuit of a starter generator with an undercurrent controller. This unit controls the starter generator when it is used as a starter. Its purpose ... starter; the other, the undercurrent relay, controls the operation of the motor relay. Figure 5-16.

  Chapter 5: Engine Starting Systems › Gas Turbine Engine Starters

  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…

  Chapter 9: Aircraft Electrical System › Light Multiengine Aircraft › Power Distribution on Multiengine Aircraft

  starter generator units used to start the engines and generate DC electrical power. The system is typically defined as a split-bus power distribution system since there is a left and right generator bus that splits (shares) the electrical loads ... each sub-bus through a diode and current limiter. The generators are operated in parallel and equally carry the loads. The primary power supplied for this aircraft is DC, although small amounts of AC are supplied by two inverters…

  have different operating characteristics depending on the specific aircraft installation and operational environment. The DC generators used in turboprop airplanes double as starter motors and are called “starter/generators.” The starter/generator uses electrical power to produce mechanical torque to start ... produce electrical power after the engine is running. Some of the DC power produced is changed to 28 volt 400 cycle alternating current (AC) power for certain avionic, lighting, and indicator synchronization functions. This is accomplished by an electrical component…
