Modern turbofan engines operate by applying Newton's second law, efficiently generating thrust with benefits like better fuel economy, reduced noise, and lower emissions.
The process begins with a large fan drawing in air, with the majority bypassing the engine's core, accelerating to provide up to 80 percent of the total thrust.
A smaller portion of the air is compressed, mixed with fuel, and ignited in the combustor, creating hot gases that drive turbines.
These turbines power the front fan and compressors, while the exiting exhaust gases provide the remaining thrust, completing the continuous cycle.
Take a close look at the inner workings of a modern turbofan engine and you’ll discover a marvelous network of parts that puts Newton’s second law of motion to work with elegance and surprising simplicity, allowing today’s jets to go farther on less fuel while making less noise and emitting lower emissions. Here’s how a turbofan works:
