Inside the Rolls-Royce Jet Engine Factory.

Описание: Inside the Rolls-Royce Jet Engine Factory. How does a jet engine not melt? Jet engines operate at temperatures exceeding the melting point of their components. This video explores the materials science behind turbine blade construction, revealing the intricate design and manufacturing processes. From initial wax molds to advanced nickel superalloys and single-crystal structures, learn how these blades withstand extreme conditions.
Why don’t jet engines melt even though their combustion chambers run hotter than many metals? In this cinematic deep dive we go inside a modern turbofan to reveal the engineering secrets — single-crystal turbine blades, nickel superalloys, film cooling, and the production tricks Rolls-Royce uses to build parts that run at 1,500°C.

▶ What you’ll learn in this video:
• How a turbofan creates thrust and why 80% of thrust comes from the front fan
• Why turbine blades face extreme centrifugal forces and molten-sand erosion
• The role of nickel superalloys and the gamma / gamma-prime microstructure
• How single-crystal casting, internal cooling passages, and ceramic coatings stop blades from melting
• Real factory footage and tests that show blades surviving in the harshest conditions
