May 19, 2014 · Turbofan is the most efficient engine and most of the thrust is produced from the bypass air. The efficiency of the engine mainly depends on the engine bypass ratio. Turbojet is mainly used …

Nov 4, 2019 · The thrust from the hot combustion products coming out the back is minor. In a low-bypass turbofan, a good fraction of the thrust still comes from the jet part so it's part way between a …

Mar 6, 2023 · The Fan Pressure Ratio (FPR) is part of the Overall Pressure Ratio (OPR, ratio of highest to lowest pressure in your primary gas path from inlet to combustor). The importance of the FPR …

Nov 4, 2018 · In jet engines, I read that thrust is related to the fuel flow rate, whereas in turboprop engines power produced is related to the fuel flow rate. What is the reason and brief math behind this?

Oct 19, 2019 · Similarly, why is power available (nearly) constant with speed for a propeller engine, while it varies for a jet engine?

What is the operating temperature of a turbofan engine? If advancements were made to materials through material science for the internal components would increasing the operating temperature …

Feb 28, 2023 · The turbofan that you see in the video is a "geared turbofan". In this kind of engines the fan is not directly connected to the same shaft of the turbine (s) but there's a gearbox between the …

Apr 5, 2018 · There are two advantages; It's easier to match the compressor rotational speed with the turbine. Typically, the first stages of the compressor want to rotate slower than the turbine is required …

Dec 15, 2019 · This thrust contributes to the total thrust of the engine. How much will depend on the bypass ratio of the engine and other parameters, but 80% is plausible for a high bypass turbofan. …

Dec 9, 2021 · What we want to achieve is the behaviour of a low bypass turbofan engine from sea level at Mach 0 to an altitude of 15000 meters and Mach 2.1 Easiest done with the 2nd graph type, since …
