RAM AIR FAN MOTOR COOLING
First Claim
1. A ram air fan assembly comprising:
- a ram air fan disposed at a fan inlet;
a ram air fan motor operably connected to the ram air fan; and
a blower operably connected to the ram air fan, the blower configured to redirect a cooling flow across the ram air fan motor from a substantially axially directed flow to a substantially radially directed flow thereby increasing the cooling flow across the ram air fan motor.

Abstract
A ram air fan assembly includes a ram air fan disposed at a fan inlet and a ram air fan motor operably connected to the ram air fan. A blower is operably connected to the ram air fan and is configured to redirect a cooling flow across the ram air fan motor from a substantially axially directed flow to a substantially radially directed flow thereby increasing the cooling flow across the ram air fan motor. A method of cooling a ram air fan assembly includes urging a cooling flow toward the ram air fan motor and is directed across the ram air fan motor thus removing thermal energy from the ram air fan motor. The cooling flow proceeds across a blower operably connected to the ram air fan motor, thus directing the cooling flow substantially radially outwardly toward the fan inlet.
