Considerable research and development effort is going into increasing the maximum Tt4 in gas turbine engines for fighter aircraft. For a mixed- flow turbofan engine with 7r~. = 16 at a flight condition of Mo = 2.5 and To = 216.7 K, use the PARA computer program to determine and plot the required engine fan pressure, specific thrust, and specific fuel consumption vs Tt4 over a range of 1600 to 2200 K for bypass ratios of 0.5 and 1. Use hpR=42,800kJ/kg, Cp= 1.004kJ/(kg-K), and y = 1.4. Comment on your results in general. Why do the plots of specific fuel consumption vs specific thrust for these engines all fall on one line?
