🔍 Key Concepts

• Impulse vs. reaction turbine stages in marine steam turbines • How a Rateau stage expands steam pressure and converts it to velocity • The typical arrangement of nozzles (fixed blades) and moving blades (rotor blades) in an impulse stage

💭 Think About

• Ask yourself: In a classic impulse turbine stage, where does most of the pressure drop occur: across the nozzles or across the moving blades? • Think about whether a basic Rateau stage repeats within the stage (multiple rows) or is a single sequence of nozzle then moving blades. • Compare the options by imagining the steam path: nozzle → moving blades → (next stage). Which arrangement matches that simplest path?

✅ Before You Answer

• Verify that a Rateau stage is an impulse type stage, not a reaction type. • Confirm that in a pure impulse stage the pressure drop is concentrated across the nozzles, with mostly velocity change (not pressure) in the moving blades. • Check which option has the simplest one-pass sequence of fixed nozzles followed by moving blades, suitable as a basic building block for multiple stages.
