Turbine manufacturing process

  1. 1. Turbine ManufacturingGas Turbine<br />
  2. 2. Overview of the Report<br />Simple Definition of parts of the Gas Turbine<br />Materials needed in Gas Turbine<br />Gas Turbine Manufacturing with videos<br />
  3. 3. Parts of the Gas Turbine<br />
  4. 4. Parts of the Gas Turbine<br />
  5. 5. Gas Turbine<br />A type of internal combustion engine<br />It has an upstream rotating compressor and a downstream rotating turbine and a combustor in-between.<br />
  6. 6. Parts of the Gas Turbine<br />1.) Inlet<br />Brings free stream air to the engine<br />Three types of Inlet:<br />a.) Subsonic Inlet<br />b.) Supersonic Inlet<br />c.) Hypersonic Inlet<br />
  7. 7. Parts of the Gas Turbine<br />
  8. 8. Parts of the Gas Turbine<br />Compressor<br />
  9. 9. Parts of the Gas Turbine<br />2.) Compressor<br />Increase the pressure of the incoming air before it enters the combustor<br />Large influence to engines performance<br />
  10. 10. Parts of the Gas Turbine<br />
  11. 11. Parts of the Gas Turbine<br />Turbine<br />
  12. 12. Parts of the Gas Turbine<br />3.) Turbine<br />Extract energy on the hot air flow from the burner<br />
  13. 13. Parts of the Gas Turbine<br />
  14. 14. Parts of the Gas Turbine<br />4.) Burner<br /> heats the air at constant pressure<br />Also known as a combustor or a combustion chamber<br />
  15. 15. Parts of the Gas Turbine<br />5.) Nozzle<br />It is use to produce thrust<br />
  16. 16. Parts of the Gas Turbine<br />
  17. 17. Parts of the Gas Turbine<br />
  18. 18. Jet Engine<br />One type of a Gas Turbine<br />The power plant of today's aircrafts<br />It produces thrust<br />It gives power to the aircraft’s whole system<br />
  19. 19. Jet Engine<br />
  20. 20. Jet Engine<br />Cowling – an external casing that opens outward to have an access to inspections<br />Pylon – a metal arm that connects the wing of the plane and the engine<br />must be very strong, since an engine can weigh up to 10,000 pounds<br />
  21. 21. Jet Engine<br />Titanium - Strong, lightweight, corrosion-resistant, thermally stable component<br />It is very difficult to shape, its extreme hardness renders it strong when subjected to intense heat<br />
  22. 22. Titanium<br />To improve its malleability, it is often alloyed with other metals such as Nickel and Aluminum<br />
  23. 23. Materials<br />Titanium<br />Intake fan<br />Thrust Reverser<br />Inner exhaust duct<br />Aluminum<br />Intermediate compressor<br />Nickel – Titanium<br />Pressure section near combustor<br />Combustion chamber<br />
  24. 24. Materials<br />Nickel – Aluminum – Titanium<br />Turbine blades<br />Composites<br />Outer exhaust duct<br />
  25. 25. Manufacturing<br />
  26. 26. Fan Blades<br />
  27. 27. Fan Blades<br />Each fan blade consists of two blade skins produced by shaping molten titanium in a hot press<br />When removed, each blade skin is welded to a mate, with a hollow cavity in the center. To increase the strength of the final product, this cavity is filled with a titanium honeycomb.<br />
  28. 28. Compressor Disk<br />
  29. 29. Compressor Disk<br />For a long time, the most popular way to manufacture the disc entailed machine-cutting a metal blank into a rough approximation of the desired shape, then heating and stamping it to precise specifications<br />Today, they use powder metallurgy<br />
  30. 30. Turbine Blades<br />
  31. 31. Turbine Blades<br />are made by forming wax copies of the blades and then immersing the copies in a ceramic slurry bath. <br />After each copy is heated to harden the ceramic and melt the wax, molten metal is poured into the hollow left by the melted wax.<br />
  32. 32. Compressor Blades<br />
  33. 33. Compressor Blades<br />Casting- an extremely old method, is still used to form the compressor blades. <br />In this process, the alloy from which the blades will be formed is poured into a ceramic mold, heated in a furnace, and cooled. When the mold is broken off, the blades are machined to their final shape<br />
  34. 34. Combustion Chamber<br />
  35. 35. Combustion Chamber<br />Welded together before being mounted on the engine.<br />Made of titanium<br />
  36. 36. Exhaust System<br />The inner duct and the afterburners of the exhaust system are molded from titanium<br />while the outer duct and the nacelle (the engine casing) are formed from Kevlar<br />
