Turbocharged gas turbine engine with electric power generation for small aircraft electric propulsion

A power plant for an aircraft propelled by at least one propulsor fan, the power plant comprising:

• a low spool having a low pressure compressor driven by a low pressure turbine;
• a high spool having a high pressure compressor driven by a high pressure turbine;
• a combustor positioned between the high pressure compressor and the high pressure turbine;
• an outlet of the low pressure compressor is connected to an inlet of the high pressure compressor;
• the low pressure turbine includes a variable inlet guide vane;
• the low pressure turbine is located adjacent to the high pressure turbine and hot exhaust from the high pressure turbine flows into the low pressure turbine;
• a main fan driven by the low spool;
• an electric generator driven by the high spool;
• an exhaust nozzle to receive hot exhaust from the low pressure turbine;
• the high pressure turbine having turbine hot parts with internal cooling air passages;
• and
• an intercooler with a boost compressor connected to the low pressure compressor and the combustor through the internal cooling air passages of the turbine hot parts.
