WebMay 30, 2015 · Fig 31: TSFC and u9/u19 as function of βf and BPR for a Turbofan with separated flux (βc=20, Ta=290K, T4=1400K, M=0). Therefore, if the β f is fixed, by increasing BPR , the specific thrust will decrease (Fig 30), because its value changes from u 9,0 (obtained by the available work c p (T 41 -T 9 ) at downstream of turbine when BPR=0) to … WebGeneral Electric GE9X. The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aviation for the Boeing 777, with thrust ratings from 81,000 to 115,000 lbf (360 to 510 kN).
