Notes

This class implements properties for rocket-grade RP-1, a highly refined kerosene fuel specifically designed for rocket propulsion. Properties are optimized for use with liquid oxygen in bipropellant rocket engines.

Definitions

‘Isentropic Expansion Factor’

Ratio of specific heats (cp/cv) for exhaust products

‘Combustion Temperature’

Theoretical maximum temperature achieved in the combustion chamber

‘Gas Specific Constant’

Individual gas constant for combustion products mixture

Major Assumptions

  • Properties are for rocket engine operating conditions

  • O/F ratio of 2.27 (oxygen to fuel mass ratio)

  • Uniform mixture properties
