Question 91Gas Turbine - 1st Asst/Chief70% to pass
You are preparing for a borescope inspection of a GE LM2500 gas turbine engine. You are reviewing the correct geometric orientation nomenclature which includes which of the following?
AI Explanation
The correct answer is A) All references left, right, and radial are orientated as viewed from aft looking forward on the engine.
This is the correct answer because the standard convention for gas turbine engine orientation is to reference all directions from the aft (rear) of the engine, looking forward. This ensures a consistent frame of reference when inspecting or working on the engine components. The other options are incorrect because they either reverse the orientation (B), or reference the flow path from a different perspective (C and D).
Maintaining this standard aft-to-forward orientation is crucial for clearly communicating engine geometry and issues during borescope inspections and other maintenance activities. This helps ensure the work is performed correctly and safely on the complex gas turbine engine.
