Aerodynamics is a mix of subsonic, transonic and supersonic airflow on a single fan/gas compressor blade in a modern turbofan. The airflow past the blades has to be maintained within close angular limits to keep the air flowing against an increasing pressure. Otherwise the air will come back out of the intake. The Full Authority Digital Engine Control (FADEC) needs accurate data for controlling the engine. … WebDetermine the specific thrust T / ˙ m a and the TSFC. a. e p a p a 3 4 5 a u 2 7 6 7 MIXING REGION u.

At the cruise condition, the flight and engine operating conditions are (1) TSFC in mg/s/N (g) all engine efficiencies op and n. M = 0.88, P. = 15 kPa, To = -40°C, Y = 1.4, N 1004J/kg. 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.
WebMay 13, 2024 · F = (m dot * V)e + bpr * (m dot)c * Vf - (m dot * V)0. Because the fuel flow rate for the core is changed only a small amount by the addition of the fan, a turbofan generates more thrust for nearly the same amount of fuel used by the core. This means that a turbofan is very fuel efficient. In fact, high bypass ratio turbofans are nearly as fuel ... 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.
