Occupations | Performs combination of following duties to produce solid-propellant rocket fuel, prepare rocket motor cases for inserting propellant, cast and cure propellant, install propellant and ignition components in motor case, prepare assembly for static testing, and pack assembly for shipment: Blends fuel ingredients and tends roller mill that grinds mixture to uniform consistency from remote control instrument panel, viewing operations on television monitor. Lowers motor case into degreasing pit filled with solvent, using hoist. Transfers case to sandblasting cabinet and starts compressor to sandblast unit, removing rust and scale. Paints motor case, using spray gun. Weighs out prescribed ingredients for insulating interior of case and starts agitator in mixing tank to blend ingredients to desired consistency. Sprays insulating liner onto case interior, using spray gun. Hoists case into oven to cure lining preparatory to inserting propellant. Fills fuel transfer can with propellant mixture, according to prescribed safety procedures, bolts lid onto can, and starts vibrator to remove air bubbles from mixture. Transfers filled can to casting area, using lift truck. Brushes mold-releasing lubricant onto casting core to facilitate removal of propellant after curing. Positions motor case in rack or pit and aligns casting core in case, using gauge and following markings on case interior. Couples safety hose to valve in lid of transfer can and turns air valves to force propellant into case. Bolts hydraulic jack to retainer ring of case and turns valve from behind safety barrier to force core into position, using system of mirrors to regulate movement of core. Slips plastic bag and metal cap over assembly and transfers filled case to curing oven. Sets automatic temperature controls of oven according to critical specifications for each type of propellant and size of motor. Removes casting core from propellant after prescribed curing time, using hydraulic jack, and trims excess propellant from rim of case, using remote controlled air-powered knives. Secures retaining collars, exhaust nozzle, ignition cable, and igniter motor in motor case, using torque and impact wrenches, to ensure alignment of all components. Hoists motor onto cradle of scale and records weight. Determines center of gravity of assembly, using centering devices and standard formula. Stencils identity and motor specifications on case, using stencil and roller. Prepares assemblies for static testing by transferring units to and from temperature-controlled rooms, securing them to test stand, recording test instrument readings, and disassembling faulty units for inspection. Slides completed assemblies into pressurized shipping containers, using hoist and aligning devices to prevent damage during shipment. Seals container, using gaskets, bolts, tape, resilient packing, and moisture-absorbing agents. May be known as Mold-Release Worker (chemical); Rocket-Assembly Operator (chemical). When casting smaller fuel elements in molds to produce free-standing grain (fuel element), wrapping grain in inhibitor sheath to control rate of burning, and manually loading grain into motor case or container, is designated Technical Operator, Grain Preparation (chemical).

| Sets up and operates small-scale chemical production equipment under laboratory conditions to test methods and chemical processes for product development, following specifications and guidance from research chemists or engineers: Sets up production equipment, such as reactors, stills, stripping towers, separators, and blending tanks, using mechanics' handtools and portable power tools. Starts pumps and compressors. Turns valves to regulate equipment temperatures, pressures, flow rates, and liquid levels, following process specifications or instructions of technical personnel. Observes meters and gauges to verify process conditions. Performs standard quantitative or qualitative chemical analyses, such as titration, distillation, caustic-insoluble, and color-measurement tests, to verify process conditions and compile research data. Mixes chemical solutions as directed for use in tests. Prepares operating records and reports of test results. May adjust and repair mechanical and electronic testing equipment, using handtools, circuit diagrams, and maintenance manuals. (references) | |
| Tends mixing machine, evaporating pans, grinding mills, and drying oven that process powdered ingredients into granulated effervescent salts for use in drug preparations: Dumps prescribed quantity of citric acid crystals into mill and starts machine to grind crystals. Starts mixer and adds ground crystals and specified amount of powdered ingredients to blend for designated time. Sets thermostat to regulate temperature of steam-jacketed evaporator pans, and dumps mixture into pans to heat for specified period and remove moisture. Inserts screen in mill and dumps contents of evaporator pans into machine to granulate to uniform size. Scoops granules into trays. Places trays in drying oven for predetermined time. Dumps or scoops dried granules into hopper or chute for transfer to storage or packaging area. May screen granules to remove particles smaller than specified size, using sieve. (references) | |
