Web1 de jun. de 2024 · A low molecular weight propellant is desirable because for a given chamber temperature, the lower the molecular weight, the higher the resulting I SP (or Specific Impulse, a measure of rocket engine efficiency); e.g. H2 provides ~900 seconds I SP at a fuel temperature of ~2800K, while comparably using H2O in an NTP system … Web31 de out. de 2024 · The highest specific impulse for a chemical propellant ever test-fired in a rocket engine was lithium, fluorine, and hydrogen (a tripropellant ): 542 seconds …
Which engine has the highest specific impulse? – ShortInformer
Web1 de out. de 2015 · The higher the specific impulse, the more “push off the pad” you get per each pound of fuel. The LH2-LOX propellant has the highest specific impulse of any commonly used rocket fuel, and the … WebHigh values of specific impulse are obtained from high exhaust-gas temperature, and from exhaust gas having very low (molecular) weight. To be efficient, therefore, a propellant … ironcraft stroud

WebSpecific impulse (often shortened to I sp) is a way to describe how well a rocket performs. It is also used to describe how well a jet engine performs. It can be used to compare rockets of different sizes. It is a way to know how much force a given engine makes for each bit of fuel. To do this, one needs to know how much fuel is in the engine.
