Abstract : This Phase 2 technical report includes a review of the fabrication, assembly, debugging, and initial trial of the mechanical equipment to generate 30 ft. to 100 ft. diameter foam-in-place urethane dome structures. A commercial hydraulic telescoping rotary boom was produced and delivered by Fulton Industries, Inc. MOOG, Inc. furnished the automatic control system packages. Dow fabricated and assembled the pumping module and forming head systems which were integrated with the Fulton equipment to complete the package unit. After assembly, the preliminary debugging, trial wall sections were made on a polystyrene foam starter ring. These wall sections were tested and appeared satisfactory structurally.
