Claims11
A filter for a radially outward flow gas generator comprising:
- a radially resilient tubular assembly having a longitudinal slit formed therein extending the length thereof, and including:
- a. fluid permeable outer support means;
- b. inner support means formed of fluid permeable material and disposed radially inwardly of said outer support means and including means for longitudinally closing the radially inward end of said slit to prevent the passage of gas through the slit;
- and
- c. a plurality of layers of generally tubular concentric deformable fibrous filter material, disposed between said inner and outer support means each having longitudinal slits which are aligned with one another such that they all lie in substantially the same plane, said sheets being adapted to effect filtration of the combustion products of the gas generator.
