A turboshaft engine is a type of turbo engine that uses the airflow generated by the combustion chamber to drive a free turbine to output shaft power instead of jet thrust. Structurally similar to a turboprop engine, the main difference is that the exhaust gases emitted by the turboprop engine also produce some residual propulsion. In addition, for turboprop engines, the main reducer of the drivetrain is integrated into the engine, while for the turboshaft engine, it is separated. Turboshaft engines are mostly used in helicopters, tanks, hydrofoils and so on. It was first designed and manufactured in 1948 by the French engine manufacturer Turbomeca.

WHAT IS A TURBINE SHAFT USED FOR?
The turbine shaft connects the turbine to the generator, turning at the same speed as the turbine. It is essentially an item that is used in machine designed for producing continuous power. The system it is used in basically extracts energy from a fluid flow and then converts it into a usable form or medium. You will often find large turbines in power generation sector, where they play a keep role in the successful running of these types of units.

HOW ARE TURBINE SHAFTS MADE?
As with other types of large shafts, they need to be produced in a way that will optimise the durability and performance levels when they are installed. Turbine rotor shafts are commonly made of steel grades 25Cr1Mo1VA, 30CrNi3Mo1VA, 26CrNi3Mo2VA, 23CrMoNiWV88 and X750. Turbine shafts are mainly machined through turning and groove-cutting operations with some amounts of drilling. Large amounts of metal are removed and demanding grooves have to be cut.
