ABSTRACT:
An augmentor system for a gas turbine engine is drained of residual fuel after augmentor shutdown by means of a drain conduit connected to the augmentor fuel spray apparatus through a valve which opens upon augmentor shutdown. The outlet to the drain conduit is disposed within the flameholder. A pressure differential causes the residual fuel to flow from the spray apparatus into the drain conduit and thereupon into the flameholder, whereupon it is burned.
