This work studies the SCRAM jet engine using the First Law of Thermodynamics to analyse and study the effect of cyclic static temperature ratio and equilibrium heating value on the efficiencies of the engine. Thermal, cycle, propulsive and overall efficiencies were studied while a brief study of component efficiencies on their influence on overall efficiency was studied. It was seen that the optimum value of cyclic static temperature ratio was close to 7 and the overall efficiency depended upon the expansion efficiency the most. The study was conducted by the use of mathematical formulation and a rigorous excel code.
