What engine is used for jets?

The engines used for jets are typically gas turbine engines, specifically turbofan engines. Turbofan engines are a type of jet engine that uses a combination of a gas turbine and a fan to generate thrust. The fan is located at the front of the engine and draws in air, which is then compressed by the fan blades. The compressed air is then mixed with fuel and burned in the combustion chamber, creating hot gases. These hot gases expand and pass through the turbine blades, causing them to rotate. The rotation of the turbine blades drives the fan, which provides most of the thrust for the jet. The exhaust from the turbine is also used to provide additional thrust. Turbofan engines are efficient and powerful, making them the preferred choice for most commercial and military jets.
