A key portion of this program is the development of tools to evaluate the fire suppression performance of new candidate extinguishants for use in suppressing in-flight aircraft fires.

The flow patterns in the device have been modeled to extend the applicability of the experimental results to a variety of conditions prevalent during aircraft fires. |
