A fixed core engine model is developed in NPSS to study the performance of N+3 technology level turbofan engine. NPSS model is validated against the results obtained from fundamental propulsion equations coded in MATLAB for a conventional Jet-A fuel. The results from NPSS and MATLAB codes for variation in Thrust Specific Fuel Consumption (TSFC) with Bypass Ratio (BPR) are compared; good agreement is obtained. The validated NPSS is then used to study the performance of N+3 engine using liquid hydrogen and ammonia as fuels. The comparisons for the variation of TSFC with BPR are presented using alternative fuels.
