What is housed in the NO.3 strut of a gas turbine engine?

The NO.3 strut of a gas turbine engine specifically houses the radial drive shaft. This component plays a critical role in the functioning of the gas turbine by transferring power from the turbine to the accessories and other parts of the engine, which may include elements such as the fuel pump and other pneumatic accessories.

Understanding the role of the radial drive shaft is essential as it connects the high-speed, rotating components of the turbine to the components that require rotational motion to perform their functions. This integration is crucial for efficient operation and effective energy transfer within the gas turbine system. The positioning of this shaft in the NO.3 strut is designed to optimize the overall performance and reliability of the engine, ensuring that power is consistently supplied where it is needed.

The other components mentioned, such as turbine blades, the engine control unit, and the exhaust outlet, have their specific placements and functions within a gas turbine engine but are not located within the NO.3 strut. This distinction helps clarify the structural organization of components within the gas turbine, contributing to the overall understanding of engine design and maintenance.
