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 ).
