http://spacecraftintl.com/ 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 … Zobraziť viac 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, … Zobraziť viac 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 … Zobraziť viac • RPA - Design Tool for Liquid Rocket Engine Analysis • List of Specific Impulses of various rocket fuels Zobraziť viac 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 … Zobraziť viac • Jet engine • Impulse • Tsiolkovsky rocket equation • System-specific impulse Zobraziť viac
