This invention relates to methods of fabricating components of a pressure vessel using a dicyclopentadiene prepolymer formulation in which the purity of the dicyclopentadiene is at least 92% wherein the formulation further comprises a reactive ethylene monomer that renders the prepolymer formulation flowable at ambient temperatures and to pressure vessels that are fabricated by said methods.

A semi-ellipsoidal, semi-toroidal, or toroidal shell includes an annular sheet metal wall that is longitudinally segmented so as to include a plurality of annular wall segments. Each of the plurality of annular wall segments is joined to an adjacent wall segment by a respective latitudinal wall weld. Also disclosed is a tank including the shell, a vehicle including the shell, a multi-conic preform used to manufacture the shell, a method for assembling the preform, and a method for manufacturing the shell using the preform.

Dismountable aeronautical pod device 30 with cryogenic storage capacity, for external transportation by an aircraft, comprising a front cryogenic tank 36, a rear cryogenic tank 37, and at least one central temporary storage tank for the rise in pressure of the gas supplied by the front cryogenic tank 36 and the rear cryogenic tank 37.

A toroid pressure vessel includes a toroid body having an inner shell and an outer shell. The toroid body includes a toroid outer perimeter. The outer shell extends along the toroid outer perimeter. A planar exterior face extends along at least a portion of the outer shell and the toroid outer perimeter. A support belt circumscribes the toroid outer perimeter and is coupled along the planar exterior face. The support belt braces and supports the pressure vessel along the toroid outer perimeter against bulging force (and hoop stress) generated by pressurized fluids within the vessel. The support belt facilitates the use of thinner pressure vessel shells and thereby decreases the weight of the pressure vessel while providing a support to the outer shell that substantially prevents deformation of the planar exterior face.
