Impulse rocketry

Witryna4 mar 2024 · This is why rocket engines have different specific impulse and thrust numbers quoted for sea level and vacuum conditions. Consequently, the engines designed for the lower stages of a rocket tend to expand their exhaust less than the engines designed for the upper stages of a rocket, because they have to operate … WitrynaThe specific impulse is a concept similar to the fuel efficiency in automobiles, which is measured in miles per gallon or kilometers per liter of fuel. In rocket or airplane engines the specific impulse represents the trust per unit propellant flow rate. In other words, it represents the force generated with respect to the fuel material used in a given …
