WebDec 5, 2024 · So if we had a rocket of 1000 kg, that had a fuel tank of 1000 kg, where mass would magically reappear so that its total mass remained 1000 kg even when expelling fuel, and this rocket had engines with a specific impulse of 4 km/s, we can now conclude that this rocket could reach a maximum speed of 4 km/s. Now such a rocket is impossible. WebThe petroleum used as rocket fuel is a type of highly refined kerosene, called RP-1 in the United States. Petroleum fuels are usually used in combination with liquid oxygen as the oxidizer. Kerosene delivers a specific impulse considerably less than cryogenic fuels, but it is generally better than hypergolic propellants. WebJul 22, 2024 · The gauge for rating the efficiency of rocket propellants is specific impulse, stated in seconds. Specific impulse indicates how many pounds (or kilograms) of thrust are obtained by the consumption of one pound (or kilogram) of propellant in one second.

WebA modern solid fuel rocket has a specific impulse of up to approximately 2500 N s kg -1 whilst a good liquid fuel rocket can produce up to 4500 N s kg -1. It is common practice … WebThe Specific Impulse of any rocket engine is determined to a large degree by the type of fuel it uses. To date, liquid hydrogen has proven to be the most fuel-efficient propellant for launch vehicles and is commonly used in the upper stages of many orbital rockets.

WebA modern solid fuel rocket has a specific impulse of up to approximately 2500 N s kg -1 whilst a good liquid fuel rocket can produce up to 4500 N s kg -1. It is common practice to take a shortcut in the units, at ground level one kg of propellant weighs a little under 10 N and these two figures are cancelled out. 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.
