Definitions

  • This invention pertains to the manufacture of reinforced hollow articles, and, more particularly, to the manufacture of pressure vessels reinforced lwith wound lilamentary material.
  • the apparatus of this invention has particular appl-ication in the reinforcement winding of pressure vessels which lare generally of cylindrical shape with hemispherical ends.
  • pressure vessels may be so rein-forced with continuous iilarnentary material that the ultimate tensile strength of the lamentary material is utilized without the necessity for excessive layers of reinforcement maten'al which would result in prohibitive finished weights, requiring even more undesirable additions tothe airframe structure containing the vessel.
  • the weight advantage thus :gained may then be used for larger paylo-ads or increased fuel loadings.
  • filament reinforced pressure vessels have long been recognized, they have not been fully realized due to the problems which arose in winding doubly curved surfaces such as the hemispherical ends of elongated cylindrical vessels. These surfaces :are Lmost advantageously reinforced by winding the reinforcement in a ser-ies of geodetic loops from a location at, or as near as possible to, one end or pole portion of the article to Ia corresponding location at or correspondingly near the opposite end of a longitudinal axis through the article. of such vessels are easily reinforced by circumferential traverse winding.
