DEVELOPMENT OF MECHANICAL FITTINGS. PHASES 1 AND 2

Abstract

The purpose of this program was to develop a family of improved lightweight mechanical fittings for service with rockets' fluid systems under stringent environmental and operating conditions. The work consisted of (1) a review of the design and use of present fittings for missiles, (2) a review of candidate materials for the required operating conditions, (3) the establishment of recommended classifications for improved fittings, (4) the development of a design procedure for flanged fittings, and the preparation of typical designs, and (5) the design, fabrication, and laboratory evaluation of a 1/2-inch threaded fitting. Three major conclusions were drawn from this program: (1) the reconnectable union should be either threaded or flanged; (2) the connection between the tube and the fitting should be a permanent joint made independent of the seal mechanism or the reconnectable union, and (3) a helium-tight disconnectable fitting which incorporates a yielding radial seal can be achieved in tubing sizes of 1-in. diameter and less.
