The fan blades are moving so fast that they essentially act like a rubber skin; as soon as a gap opens up, the next blade arrives to cover it, maintaining a permanent wall of movement that prevents high-pressure air from escaping.

How the fan in a turbine engine works
常见问题
The fan is the first major component of a turbofan engine, acting as a large-scale propeller that pulls massive amounts of air into the system. It accelerates this air to create thrust, with a significant portion of the air bypassing the engine core. This process is fundamental to modern aviation propulsion, as it provides the necessary force to move the aircraft forward efficiently while maintaining lower noise levels compared to older jet designs.
The bypass ratio refers to the amount of air that flows around the engine core versus the amount that passes through it. In modern turbine engines, a high bypass ratio is preferred because the large fan can move a high volume of air at lower speeds, which is much more fuel-efficient for commercial flight. This mechanical balance allows for greater thrust and improved fuel economy, making it a critical factor in gas turbine mechanics and design.
A turbofan engine consists of several key components including the large front fan, the compressor, the combustion chamber, and the turbine. The fan initiates the process by drawing in air, which is then split between the core and the bypass duct. Inside the core, the air is compressed, mixed with fuel, and ignited. The resulting high-energy exhaust spins the turbine, which is connected by a shaft to drive the front fan, completing the propulsion cycle.
