How A Jet Engine Works 2023

Hi, I'm XE, Williams International's XJet. I introduced the world to personal flight, so I know a lot about turbine engines, and I'd like to show you how they work. Jet engines produce power by compressing air, adding fuel, and releasing the energy in the fuel. A jet engine performs a similar function to the piston engine in a car, but works differently. Instead of igniting the fuel intermittently to drive pistons up and down, the jet engine burns fuel continuously to maintain a stream of hot gases. This stream can be used to push an airplane through the air or to keep aircraft flying, or it can be used to drive other devices like propellers or generators. Now let's look inside to follow the air as it passes through the engine. Major components of a jet engine are the compressors, the combustor, and the turbine. When the engine is running, that compressor draws air into the engine. The job of each stage of the compressor is to squeeze the air until its pressure is many times higher than the outside air. The temperature of the air as it is squeezed so hard rises to nearly 1,000 degrees Fahrenheit. After passing through the compression section of the engine, the air enters the combustor, fuel is mixed with the compressed air in the combustor, where a continuous burning process releases a great amount of energy in the form of even higher temperature. The hot gas stream exiting the combustor can be over 3,000 degrees Fahrenheit. As the hot gas stream leaves the combustor, it passes through the turbine. The turbine is connected to the same shaft as the compressor so they rotate together as one piece. That turbine extracts a lot of power from the hot gas stream to turn the compressors while they squeeze the air and raise the pressure. Properly designed, the engine will not only develop enough power to keep itself running, it will have enough excess power in the form of expanding high-pressure gas exiting the rear of the engine to push a plane through the air. This remaining force is called thrust. Jet engines can produce an incredible amount of power for their weight, which is one reason they're so popular in aircraft. Thanks to their continuous combustion, jet engines also produce cleaner exhaust and less noise for the amount of power produced. They also can last a long, long time. As part of the Williams Blue Planet initiative to decarbonize aviation, all Williams engines are approved today to use up to 50% sustainable aviation fuel. Williams has already demonstrated its engines using 100% sustainable aviation fuel in flight tests. It's people like you who will design, build and fly these machines. Maybe you will be honored in a museum someday for future generations to see what you made. Bye! Come back soon!
