Abstract: A hybrid engine system including a turbine engine having a fan section, a compressor section, a combustion section, a turbine section, a shaft coupled to the compressor section, and a nacelle circumferentially surrounding the fan section. A duct extends from the nacelle upstream of the fan section. An electrical power generator is mechanically coupled to the shaft, the electrical power generator being configured to convert at least a portion of mechanical power generated by the turbine engine into electrical power. A part-span inlet guide vane is disposed between the duct and the nacelle, the part-span inlet guide vane including a plurality of inlet guide vanes that are configured to rotate to adjust an amount of pressure of the airflow towards the fan section.
