| Abstract: |
| In this paper the power cycles of liquid propellant rocket engines are divided into open cycle and close cycle and analyzed.Through the analysis, formulae for the power cycle efficiency of liquid propellant rocket engines are set up.Based on those formulae, the factors effecting cycle efficiency of the rocket engines are also analyzed.The conclusions in this paper are for refference in the design calculation of the liquid propellant rocket engines. |
| Key words: Liquid propellant rocket engine Thermodynamic cycle Energy conversion efficiency System analysis |
