Webb1 okt. 2024 · Specific impulse is a measure of a rocket engine's efficiency. It is essentially the thrust per pound of propellant consumed per second. Isp = F / ṁ, where Isp is the specific impulse in seconds Although a rocket designer might be tempted to always use the highest Isp propellant combination available, the propellant density is also a factor. WebbNASAs Green Propellant Infusion Mission program is the first-ever, on-orbit demonstration of an ASCENT fueled spacecraft. DIFFERENTIATED THROUGH DELIVERED PERFORMANCE Similar to hydrazine, ASCENT monopropellants are decomposed by a reactor based thruster to produce high temperature and velocity gas.

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.
