Solar thermal rockets and nuclear thermal rockets typically propose to use liquid hydrogen for an Isp (Specific Impulse) of around 600–900 seconds, or in some cases water that is exhausted as steam for an Isp of about 190 seconds. 太阳能火箭和核能火箭通常建议使用液氢以达到600-900秒Isp(比冲...
Enhanced Specific Impulse for Nuclear Thermal Rockets Using Variable Flow Area ChannelsApeloig, J. M.Kirk, D. R.International Review of Aerospace Engineering
The energy of propellant is measurement in terms of a specific impulse inside the motor of the rocket. It depend upon the flame temperature and average molecular mass of the gaseous products coming ot of the rocket nozzle. The specific impulse is given b
Specific impulse is a measure of efficiency forrocketengines. It is the change in momentum per unit of mass for rocket fuels. Simply put, specific impulse is a measure of how much push (thrust) accumulates as you burn the fuel. Specific impulse is a measure of efficiency for rocket engines...
The engines have been operated with electric power sources ranging from 0.5 to 30 kW and have a characteristic specific impulse in the range of 1000–1500 s [33]. Unlike chemical rockets which burn powerfully for short periods of time, these engines operate by providing small amounts of ...

Specific impulse is often used to find out how well the engine is producing thrust. This parameter is vital to compare the performance of engines of different classes, as it is only a function of thrust generated and exhaust velocity or mass flow rate. You can find more on rockets in our...
