The “28” in PT6A-28 denotes the specific model within the PT6A series, each with its own unique features and capabilities.

PT6A-28 Engine Specs

The PT6A-28 engine is equipped with various components that work together to provide reliable and efficient propulsion. Let’s delve into some of the key specifications:

HUB (Part No. 3013111)

The HUB is a critical component of the PT6A-28 engine. It plays a pivotal role in connecting the engine to the aircraft’s propeller. The design and quality of the HUB are essential to ensure a seamless transfer of power from the engine to the propeller.

C2 (Part No. 3013712)

The C2 component is an integral part of the PT6A-28 engine’s compressor section. Compressors are responsible for drawing in and compressing air before it enters the combustion chamber. The C2 component contributes to the engine’s overall efficiency and performance.

C3 (Part No. 3011713)

C3 is another vital component within the compressor section of the PT6A-28 engine. It works in conjunction with other compressor components to ensure optimal air compression, which is crucial for the combustion process.

IMPELLER (Part No. 3013176)

The impeller is a key component of the PT6A-28 engine’s turbine section. As the engine’s exhaust gases pass through the turbine, they drive the impeller. This action powers the compressor, creating a continuous cycle that generates thrust and propels the aircraft.

CT DISK (Part No. 3013411)

The CT DISK, or compressor turbine disk, is an essential element in the engine’s turbine section. It is designed to withstand the high rotational speeds and extreme temperatures generated during engine operation. The quality and durability of the CT DISK are crucial to engine safety and performance.

PT DISK (Part No. 3026812)

The PT DISK, or power turbine disk, is another critical component in the PT6A-28 engine’s turbine section. It plays a significant role in harnessing the energy from the high-velocity exhaust gases and converting it into mechanical power to drive the propeller.
