Specific impulse measures how effectively a rocket engine creates thrust from the mass it throws out the back, whether by chemical or any other means. The higher the specific impulse of a rocket ...
This would be about 20 times more efficient than most chemical rockets. Exhaust velocity would be 66 km/second. The 300 ton design has a thrust of 2.9 Mlb, and a T/W of 40 is assumed. The specific ...
In order to significantly increase the effectiveness, performance and specific impulse of future rocket engines, high combustion chamber pressures are required above all. If the combustion chamber ...

Nuclear rockets could travel to Mars in half the time − but designing the reactors that would power them isn't easyNuclear propulsion would expel propellant from the engine's nozzle very quickly ... systems have roughly twice the specific impulse of chemical rockets, which means they could cut the travel ...
