WebThe aerodynamic and mechanical design of a 3.8m engine with an OPR of 34.3 and a BPR of 6.5 was defined over the course of this project. This design provided 12.36 kN of thrust with a TSFC of 16.14 g/(kNs) at a design altitude of 40,000ft. This process began with the selection of an appropriate thermodynamic cycle using GasTurb. WebApr 28, 2012 · This graph shows how thrust and TSFC varies with M and altitude for a high bypass Turbofan. We can see that the static thrust falls a lot and that the TSFC goes to 0.7 at M 0.8 and FL350 and above. Perhaps some engine wizard could explain a bit more why? What would be the scale of effects from inlet losses?
