Web(TSFC). Turbofan engines are separated into two kinds including mixed-flow turbofan and un-mixed flow turbofan. Also it can also be divided into two parts: hot flow and by-pass flow. Also, at the unmixed flow turbofan engines the output flow of bypass channel and low-pressure turbine exhausted to the environment separately through separate nozzles. WebTURBOFAN CYCLE 5.1 T URBOFAN THRUST The figure below illustrates two generic turbofan engine designs. Figure 5.1 Engine numbering and component notation The upper figure shows a modern high bypass ratio engine designed for long distance cruise at subsonic Mach numbers around 0.83 typical of a commercial aircraft. The fan utilizes a …

WebJul 8, 2006 · CFM56-7B20 is rated at 91.6kN of Thrust. At 100% N1, it burns 0.91 KG of Fuel per second. This gives it a TSFC of 0.035752. This now means that the FFPH at cruise is around 2784.6kg per hour which when you multiply by two (for 2 engines) is equal to 5569.2. The fuel consumption of TSFC is \"how much fuel the engine burns each hour.\" The specific of TSFC is a scientific term meaning \"divided by mass or weight.\" In this case, specific means \"per pound (Newton) of thrust.\" The thrust of TSFC is included to indicate that we are talking about gas turbine engines. There is … See more If we divide both numerator and denominator by the engine airflow mdot 0, we obtain another form of the equation in terms of the fuel to air ratio f, and the … See more TSFC provides important information about the performance of a given engine. A turbojet with an afterburner produces more thrust than a plain turbojet. If the … See more Engineers use the TSFC for a given engine to figure out how much fuel is required for an aircraft to perform a given mission. If the TSFC = 0.5, and we need 5000 … See more WebThe author developed two machine-learning predictive analytics for turbofan TSFC and core-size predictions, respectively. The development used the database of 183 manufactured engines and engines that were studied previously in NASA aeronautics projects.
