Question 20Gas Turbine - 1st Asst/Chief70% to pass
When tip clang takes place on a gas turbine engine, the major damage occurs to what area of the blade?
AI Explanation
The correct answer is C) Root.
When tip clang occurs on a gas turbine engine, the major damage happens at the root of the blade. This is because the high-speed impact of the blade tip against the casing causes high-stress concentrations at the blade root, which is the weakest section of the blade. The blade root is where the blade connects to the engine rotor, and this area experiences the highest stresses during normal engine operation. The tip, chord, and midspan sections of the blade are less susceptible to major damage from tip clang events.
