Inlet Particle Separator is associated with which engine section?

• A. Hot Section
• B. Power Turbine Section
• C. Cold Section Module
• D. Accessary Gear Box Section

Answer: (C)

The Inlet Particle Separator belongs to the cold side of the engine. Its purpose is to remove sand and dust from incoming air before it reaches the compressor, protecting the compressor blades from abrasive wear and maintaining efficient airflow. Because it operates in the air intake path and feeds the compressor, it is part of the cold section module, not the hot section where combustion occurs, not the power turbine area, and not the accessory gear box. This placement keeps clean air flowing into the compressor, which is essential for reliable engine operation in dusty or sandy environments.
