| 31. | It is used to calculate the local forces on a propeller or wind-turbine blade.
|
| 32. | Nickel-based superalloys are used for HP turbine blades in almost all modern jet engines.
|
| 33. | It's normally used for such things as inspecting jet engine turbine blades for hairline cracks.
|
| 34. | By 1946 thrust had been increased to 4, 200 lb using Nimonic 90 turbine blades.
|
| 35. | :: : Large turbine blades are hard to move.
|
| 36. | The new engines suffered damage to the turbine blades, a problem not solved until 1943.
|
| 37. | The UK designs also had better materials such as the Nimonic alloys for turbine blades.
|
| 38. | As a result, turbine blades are typically monocrystalline or polycrystalline with a preferred crystal orientation.
|
| 39. | Weakened engine mounts, bad turbine blades, defective cargo doors.
|
| 40. | These coatings increased turbine blade temperature capability by about 200 �F ( 90 �C ).
