(PhysOrg.com) -- NASA's Deep Space Network personnel sent commands to the Voyager 2 spacecraft Nov. 4 to switch to the backup set of thrusters that controls the roll of the spacecraft. Confirmation was received today that the spacecraft accepted the commands. The change will allow the 34...
The thruster valve, which is one of the key components applied to the mono-propellant system for the satellite, has a circular plate spring structure. It can be designed as a structure that does not have positional deformation and partic... S Ko,M Son,N Kim,... - Korean Society of Pro...
In this case, the laser-induced plasma should be leading the main discharge from a capacitor, where a certain amount of neutral components of vaporized propellant must be ionized through the discharge. At 8.65-J discharge energy, the maximum current reached about 8000 A. With a newly developed...
ManufacturingDesignAdditive manufacturingMetalsPrior research has shown that powder bed fusion additive manufacturing (AM) can be used to make functional, end-use components from powdered metallic alloys, such as Inconel? 718 super alloy. However, these end-use products are often based on designs ...
The molecular sources contributing to the inorganic components of the plume backflow contaminant are estimated, and a qualitative characterization of the liquid droplet contribution to the organic part of contaminant is conducted. The total calculated mass flux of the molecular contaminant in the backflow...
The U.S. Naval Academy (USNA) and the George Washington University (GWU) are jointly developing components and subsystems for the first on-orbit demonstration of a novel electric propulsion system called the Micro-Cathode Arc Thruster (渭CAT). A quad-channel microthruster subsystem will be used...
