Hybrid propulsion engines for aircraft are described herein. An example hybrid propulsion engine includes a propulsor and a gas turbine engine to drive the propulsor during a first mode of operation. The gas turbine engine has a core air intake. The hybrid propulsion engine also includes an electric motor to drive the propulsor during a second mode of operation and a damper disposed in the core air intake of the gas turbine engine to block airflow through the core air intake during the second mode of operation.
