Explain what specific impulse means
Did you know?
WebSpecific impulse, like you said, is a measurement of a rocket engine's efficiency. It's given in seconds (kind of odd but I'll explain). Let's say an engine generates 10 kilograms of thrust (10 kgf for kilogram-force) and consumes one kilogram of propellant per second (1 kg/sec). WebJan 27, 2024 · Specific impulse is a measure of the efficiency of rocket fuels. It can be defined as impulse per mass (or thrust per mass flow rate), and it is equal to exhaust velocity and has the SI unit of meter per second. \ (j_ {SP} = \frac {j} {m} = \frac {T} { …
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 … See more 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, … See more 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.
