WebDec 11, 2024 · For a jet going slower than the speed of sound, the engine is moving through the air at about 1000 km/h (600 mph). We can think of the engine as being stationary and the cold air moving toward it at this speed. A fan at the front sucks the cold air into the engine and forces it through the inlet. WebIf we dive into a bit more detailed explanation, the path would be refined like this: Vanes pressure side is upward while blades pressure side is downward. 3. Taking into account blade rotation With blades rotation, blades of the second stage do move while air is traveling across the first stage.
