WebFeb 22, 2024 · Unlike a rocket engine, a ducted fan must first do work on the onflow, and the slower the onflow, the more work must be done on it. Of course the onflow in a static test is sped up before it reaches the inlet, but in flight with a faster moving onflow less work is needed to speed it up and the result is greater thrust when in flight. WebThe fast design method of the rotor and stator of the ducted fan aims to design the blade of the ducted fan that meets the thrust demand. Before the design, the design state and the …
