3. Parts of the Gas Turbine

4. Parts of the Gas Turbine

5. Gas Turbine A type of internal combustion engine It has an upstream rotating compressor and a downstream rotating turbine and a combustor in-between.

6. Parts of the Gas Turbine 1.) Inlet Brings free stream air to the engine Three types of Inlet: a.) Subsonic Inlet b.) Supersonic Inlet c.) Hypersonic Inlet

12. Parts of the Gas Turbine 3.) Turbine Extract energy on the hot air flow from the burner

13. Parts of the Gas Turbine

14. Parts of the Gas Turbine 4.) Burner heats the air at constant pressure Also known as a combustor or a combustion chamber

15. Parts of the Gas Turbine 5.) Nozzle It is use to produce thrust

18. Jet Engine One type of a Gas Turbine The power plant of today's aircrafts It produces thrust It gives power to the aircraft’s whole system

19. Jet Engine

20. Jet Engine Cowling – an external casing that opens outward to have an access to inspections Pylon – a metal arm that connects the wing of the plane and the engine must be very strong, since an engine can weigh up to 10,000 pounds

21. Jet Engine Titanium - Strong, lightweight, corrosion-resistant, thermally stable component It is very difficult to shape, its extreme hardness renders it strong when subjected to intense heat

22. Titanium To improve its malleability, it is often alloyed with other metals such as Nickel and Aluminum

23. Materials Titanium Intake fan Thrust Reverser Inner exhaust duct Aluminum Intermediate compressor Nickel – Titanium Pressure section near combustor Combustion chamber

24. Materials Nickel – Aluminum – Titanium Turbine blades Composites Outer exhaust duct

25. Manufacturing

26. Fan Blades

27. Fan Blades Each fan blade consists of two blade skins produced by shaping molten titanium in a hot press 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.

28. Compressor Disk

29. Compressor Disk 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 Today, they use powder metallurgy

30. Turbine Blades

31. Turbine Blades are made by forming wax copies of the blades and then immersing the copies in a ceramic slurry bath. 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.

32. Compressor Blades

33. Compressor Blades Casting- an extremely old method, is still used to form the compressor blades. 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

34. Combustion Chamber

35. Combustion Chamber Welded together before being mounted on the engine. Made of titanium

36. Exhaust System The inner duct and the afterburners of the exhaust system are molded from titanium while the outer duct and the nacelle (the engine casing) are formed from Kevlar
