Abstract
A fire protection device for an accessory of an aircraft engine includes a baffle located within an airflow passage in communication with the accessory, the baffle having fire shield elements made of a shape memory alloy. The fire shield elements are deformable between a deformed state and a natural state, wherein in the natural state the fire shield elements extend at least partially across the airflow passage to protect the accessory from flames, and in the deformed state the fire shield elements is bent to define one or more gaps between the fire shield elements in the air flow passage thereby allowing airflow through the baffle.
