Specific impulse (usually abbreviated Isp) is a measure of how efficiently a reaction mass engine (a rocket using propellant or a jet engine using fuel) creates thrust. For engines whose reaction mass is only the fuel they carry, specific impulse is exactly proportional to the effective exhaust gas velocity. A propulsion … Visa mer The amount of propellant can be measured either in units of mass or weight. If mass is used, specific impulse is an impulse per unit of mass, which dimensional analysis shows to have units of speed, specifically … Visa mer The most common unit for specific impulse is the second, as values are identical regardless of whether the calculations are done in SI, imperial, or customary units. Nearly all manufacturers quote their engine performance in seconds, and the unit … Visa mer • RPA - Design Tool for Liquid Rocket Engine Analysis • List of Specific Impulses of various rocket fuels Visa mer An example of a specific impulse measured in time is 453 seconds, which is equivalent to an effective exhaust velocity of 4.440 km/s (14,570 ft/s), for the RS-25 engines when … Visa mer • Jet engine • Impulse • Tsiolkovsky rocket equation • System-specific impulse • Specific energy Visa mer WebbIn electric (electrostatic) propulsion, a high-velocity jet is produced by accelerating charged particles through an electric potential. The propellant medium in electrostatic thrusters is a plasma consisting of electrons and positively charged ions. The plasma is usually produced by ionizing a gas via electron bombardment.
