INTEGRATED STARTER-GENERATOR OF MODULAR DESIGN Russian patent published in 2024 - IPC F02C7/12 H02K9/197 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly, to devices for starting an aircraft engine and aircraft onboard power supply. Integrated starter-generator of the gas turbine engine includes a stator, a rotor connected to the output shaft of the gas turbine engine, a cooling system with cooling air supply and removal channels. Integrated starter-generator is made modular and comprises a housing in which a stator with a winding and a sealed cylindrical insert is fixed, rotor with permanent magnets pressed to it by bandage, fixed on hub by means of coupling, and installed with possibility of rotation relative to stator in front and rear end shields attached to housing. At the same time the rear end shield is made in the form of a flange, and the cooling system is combined with air and liquid coolant supply and discharge channels.

EFFECT: improving reliability, energy efficiency and simplifying maintenance.
