What do jet engines look like in reality? A lot more complicated than my little picture! Here's a typical example of a large, real turbofan engine, opened up and undergoing maintenance. I've labelled eight major parts in my explanation above; as you can see here, a real jet engine has...
Turbofan enginesFansNoiseAircraftThis article presents a comparative analysis of the influence of different types of flows over fan noise propagation and scattering within the nacelle intake of aircraft turbofan engines. The methodology for the noise simulation is explained. First, the fan noise source ...
Depending on the model, it has a range of between 6,700 to 9,000 nautical miles. The A340 is similar in design to the twin-engined A330 with which it was concurrently designed. Its distinguishing features are four high-bypass turbofan engines and three-bogie main landing gears. Airbus ...
Turbofan Engines A turbofan engine is much the same as a turbojet, but with an enlarged fan at the front which provides thrust in much the same way as a ducted propeller, resulting in improved fuel-efficiency. Although the fan creates thrust like a propeller, the surrounding duct frees it ...
In this quest, turbofan engines have a trend to design with a higher bypass ratio.1, 2 The large diameter fan constrains the axial length of the intake since the propulsive system weight and drag must remain within reasonable limits. However, short intake increases the risk of flow separation...

high-speed rubbingmaterial transferflash temperatureThe tribological behaviors of two types of seal coatings, nickel–graphite and aluminum–hexagon-boron nitride (Ni–Cg and Al–hBN, respectively) versus a Ti–6Al–4V blade used in turbofan engines were investigated using a high-speed rubbing test....
A jet engine is any of a class of internal-combustion engines that propel aircraft by means of the rearward discharge of a jet of fluid, usually hot exhaust gases generated by burning fuel with air drawn in from the atmosphere.
In a more restrictive sense, rocketpropulsionis auniquemember of the family of jet-propulsion engines that includes turbojet, pulse-jet, and ramjet systems. The rocket engine is different from these in that the elements of its propulsive jet (that is, the fuel and oxidizer) are self-contained...
