🔍 Key Concepts

• Difference in operating temperature and stress between power turbine and high-temperature (gas producer) turbine stages • Typical root designs used to attach turbine blades to the rotor disc (e.g., dovetail, fir-tree, bulb roots) • Purpose of shroud tips and why some blades are left solid vs cooled/hollow

💭 Think About

• Think about which turbine stage is exposed to the highest gas temperatures and which one runs slightly cooler. How does that affect the need for special cooling or special blade constructions? • Which root fitting style is commonly used on later turbine stages where loads and temperatures are different than at the first (high‑temperature) stage? • Ask yourself: which feature is mainly used where blades do NOT need internal cooling passages and extreme thermal protection?

✅ Before You Answer

• Compare which stage (power vs high‑temperature turbine) is more likely to use hollow, cooled blades instead of solid blades • Recall which root types (dovetail, fir‑tree/bulb) are more typical on high‑stress, high‑temperature first‑stage blades • Check which option describes a feature that you would expect specifically on a lower-temperature, power‑extraction stage rather than on the hottest turbine stage
