Turbine blades are generally more susceptible to operating damage than compressor blades because of

  1. the high probability of carbon deposits

  2. exposure to high temperatures

  3. less exposure to solution during engine pressure wash

  4. lower quality material

The correct answer is: exposure to high temperatures

Explanation Turbine blades are subjected to high temperatures due to the combustion process, making them more brittle and susceptible to thermal fatigue. This is not the case for compressor blades, which operate at lower temperatures and are less prone to damage. The other options, while also potential concerns for turbine and compressor blades, do not directly address the main factor that makes turbine blades more susceptible to operating damage.
