Abstract : A filter-cooler is provided for use with a rocket motor to cool and filter highly aluminized hot gases from around 5800 F. to around 2000 F. The cooled and filtered gases are then usable, for example, in thrust vector control or other mechanisms associated with the rocket. In the present system the cooler section is placed ahead of the filter section so that alumina present in the gases begins to solidify ahead of the filter and thus may be more efficiently removed. The filter section comprises a plurality of graphite vortex producing geometries. The vortex direction of the baffles is reversed in succeeding baffles so that the net effect of the high rotational velocities of each vortex is used to separate the particulate contaminates from the gas stream by momentum.
