No particular effort had been made to maximize the specific impulse, that not being the reactor's purpose, but Pewee achieved a vacuum specific impulse of 901 seconds (8.84 km/s), well above the …

May 13, 2021 · Two different rocket engines have different values of specific impulse. The engine with the higher value of specific impulse is more efficient because it produces more thrust for the same …

The design requirements were a thrust of 250,000 pounds, a specific impulse (I sp) of 840 seconds, and a reactor power level of 5,000 megawatts. The Phoebus-1 series was intended to study increasing …

Specific impulse (Isp) is a crucial metric for rocket engines, representing how efficiently a rocket uses propellant. In a vacuum, where there's no atmospheric drag, Isp is primarily determined by the …
