Abstract
A pre-cooler system employs a powered pre-cooler fan assembly having a fan adapted to receive bypass engine fan air through an inlet plenum with an outlet guide vane array (OGVA) adapted to control airflow from the inlet plenum and fan, with a rotational power source operationally connected to the fan. A shroud directs airflow from the inlet plenum, fan and OGVA into a pre-cooler disposed downstream of the fan and OGVA.
