Which item is included in the Power Turbine Components?

• A. Exhaust Frame
• B. P3 Air Port
• C. 7 Lug Holes Engine Mount
• D. 2 Igniter Port

Answer: (A)

In a turboshaft engine, the power turbine components are the parts that make up the section where the turbine extracts energy and directs the exhaust flow. The Exhaust Frame is part of that assembly; it provides the structural support around the power turbine and serves as the mounting and routing path for the exhaust system, directing exhaust away from the turbine and into the exhaust stack. This integration with the turbine and exhaust path is why it’s included among the power turbine components.

The other items belong to other subsystems: P3 air port relates to air access/pressure in the engine’s core, not the turbine hardware; the engine mount holes are part of the mounting structure for attaching the engine to the aircraft; and igniter ports are part of the combustion/ignition system, not the power turbine itself.
