Abstract

A model for the aircraft performance including a Brayton turbofan engine cycle analysis was developed in order to study the effect of varying the fan pressure ratio and bypass ratio on the range performance of a medium-size business jet. In the classic flight mechanics treatment of aircraft performance, maximizing range requires maximizing CL1/2/CD. This classic approach, however, assumes that thrust specific fuel consumption is a constant. Previous studies, which include the effect of variation in thrust specific fuel consumption, typically seek to determine the optimum flight Mach number under a constant altitude - constant speed flight condition. This project was motivated by a desire to study what effect variations in flight conditions such as speed, lift-to-drag ratio, or thrust settings have on aircraft performance. An increase in range of approximately 2% to 8% was obtained, depending upon the bypass ratio, by maximizing U(L/D)/TSFC compared to the case where CL1/2/CD was maximized.
