Modern turbofan engines efficiently generate thrust using a four-step process (Suck, Squeeze, Burn, Blow) that minimizes noise and emissions.
The engine's large front fan draws in massive amounts of air, with the majority bypassing the core to provide up to 80 percent of the total thrust when accelerated.
The remaining air is compressed, mixed with fuel and ignited in the combustor, and then expands through turbines to power the fan and compressors, creating a continuous cycle and providing additional thrust.
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:
