WebbLike many electric propulsion concepts, it becomes more efficient as more power is applied to the system; in addition, the higher the specific impulse being used, the more efficiently it uses the electrical power available. http://www.isp.se/
Webb4 feb. 2024 · But when looking at propellant efficient (Isp) the tables turn. Here, Archimedes with a specific impulse of 329 seconds beats Merlin 1D with only 282 seconds of specific impulse. That means the same amount of fuel can provide thrust for a longer time on a Neutron rocket than a Falcon 9. It is 17 percent more propellant efficient. WebbWhile not specifically a propulsion type, propellant management devices (PMDs) are frequently used in large liquid propulsion systems to reliably deliver propellant to …
