A computerized spray chamber for rapid implementation of spray deposit experiments was developed and evaluated. The system has been in use for a number of months and has significantly improved the efficiency of running spray-related laboratory experiments. The main features of the system include time-delay system to clear spray out of the chamber before the operator opens the door, charcoal filter to filter the air before exiting the building, a spray table with adjustable height, variable nozzle speed from 0.8 to 9.33 km/h (0.5 to 5.8 mph), nozzle mounting bracket that is supplied with air pressure of 0 to 412 kPa (0 to 60 PSI), liquid pressure of 0 to 412 kPa (0 to 60 psi), and 12 Volt DC power source to accommodate hydraulic, pneumatic, or rotary (electrical) atomizers. The pressures and travel speed are displayed during an entire spray run. Electronic measurements indicated that the system was able to maintain repeatability of speed of greater than 98%. This paper describes the mechanical and electrical design and the operation of the system.

Saturn's Rings

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.
