This report covers work done on propellant formulations, motor design and testing, and igniter design for the Alecto and Cyclops II silver iodide-generating rocket motors. Propellant studies included tests on various Nitrasol and fluorocarbon propellants for extrusion production. Studies on these propellants were discontinued in favor of cast, nitroplasticized, polybutadiene-acrylic acid PBAA binder formulations that were found to be safer. Design and fabrication of the Alecto unit culminated in a 2 12-inch-diameter cast PBAA grain packaged in a modified M123 photoflash canister. The Cyclops II unit had drag fins and an 8-inch-outside-diameter motor package. Tests were performed on only a few of each type of unit. All units showed that they were applicable for flight use, and 390 Alecto units and 24 Cyclops II units were ready for use against a hurricane by September 1962.
