WebDec 20, 2014 · High-bypass turbofan engines do not create condensation trails. The ratio of air-to-exhaust is much too high to facilitate the formation of condensation because the majority of air expelled from the back of the engine is not combusted. It is passed through the "fan" and simply blown out the back without mixing with any fuel at all. WebUltrahigh-bypass engines (as shown in Figure 4) may have a gearbox between the drive turbine and the fan to simplify the design of the small-diameter turbine (with the attendant high rotative speed) without compromising the performance of the very large-diameter …

Turbofan engines come in a variety of engine configurations. For a given engine cycle (i.e., same airflow, bypass ratio, fan pressure ratio, overall pressure ratio and HP turbine rotor inlet temperature), the choice of turbofan configuration has little impact upon the design point performance (e.g., net thrust, SFC), as long as overall component performance is maintained.
