Question 9Gas Turbine - 1st Asst/Chief
70% to passZero reference for the GE LM2500 gas turbine engine is established by the use of which of the following engine components?
ALocking lug blades.
BVane blades.
CCarboloy blade pads.
DVane shrouds.
AI Explanation
The correct answer is A) Locking lug blades. The locking lug blades on the GE LM2500 gas turbine engine are used to establish the zero reference for the engine. The locking lugs on the blades fit into corresponding slots in the engine casing, which allows the position of the blades to be precisely determined and used as a reference point for engine operations and maintenance. The other answer choices are incorrect because vane blades, carboloy blade pads, and vane shrouds do not serve the specific purpose of establishing the zero reference for the engine. They are other components of the gas turbine engine, but do not perform the critical function of providing the necessary reference point.
