A turbine engine is a type of engine that converts fuel into energy to produce thrust. It works by drawing in air, compressing it, mixing it with fuel, and igniting the mixture. This process creates high-speed exhaust gases that are expelled out of the back, propelling the engine forward. Turbine engines are commonly used in aircraft, such as those found in commercial jets like the Boeing 747. These engines are known for their efficiency and power, making them ideal for high-speed travel. They can also be found in other applications, such as power plants and helicopters. Overall, turbine engines play a crucial role in modern transportation and energy production.
