Claim:
1. An aircraft intake assembly comprising: a nacelle with multiple intake side doors disposed on an outer periphery of the nacelle; an internal air injection unit having controllable impeller blades arranged on an outer periphery of the internal air injection unit, the controllable impeller blades located adjacent to the respective intake side doors of the nacelle; a shielding blade assembly having a stored configuration and an extended configuration; the shielding blade assembly having blades that retract and overlap in the stored configuration and rotate inwardly towards a centerline of the aircraft intake assembly from the stored configuration to the extended configuration, the extended configuration providing an aerodynamically closed seal to prevent airflow from flowing through the centerline of the aircraft intake assembly; a proximity sensor array for detecting incoming objects towards the aircraft intake assembly and transmitting signals in response to detecting said incoming objects to a controller that transmits command signals when detecting said incoming objects; a motor assembly configured to rotate said blades from the stored configuration to the extended configuration in response to the controller transmitting the command signals to prevent said incoming objects from entering the internal air injection unit.
