Web1 de out. de 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. WebA rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines , producing thrust by ejecting …
