IPS 3 engine frames include which of the following frame types?

• A. Swirl Frame
• B. PTO
• C. Scroll Case
• D. Inlet Particle Separator

Answer: (A)

The main idea is that IPS 3 engine frames include a specific frame type dedicated to directing and shaping the airflow within the engine. A Swirl Frame is the frame type designed for that purpose, providing the structural location and flow-deflecting features needed to create a controlled swirl before entry into subsequent stages. The other options are not frame types: a Power Take-Off is an accessory-power drive, a Scroll Case is part of the flow-path housing around a compressor impeller, and an Inlet Particle Separator is a pre-cleaning device at the inlet. Therefore, Swirl Frame is the correct frame type included in IPS 3 engine frames.
