basic and simple information about turboshaft engines is given. The basic principles of turboshaft engines described in the video may contain different structural and systemic features in different aircraft. Watching videos of turbojet and turboprop engines before watching this video will be useful for better understanding of the subject. Have a good time....
In this video we take a look at the Arriel 2 helicopter engine. We use high quality animations to explain it, as easy as it gets. The Arriel 2 is a so called turboshaft engine and later in the video we will also show the differences to other fixed wing (aircraft) jet engines.
you can see the 2 right-hand cylinder covers (Bronze Colored Squares) of this 180hp, derated to 145hp Lycoming O-360 engine. To create enough cooling airflow, Frank Robinson (The original designer of this helicopter) created this fan shroud that pulls in air from the large round air inlet, goes through an engine-driven, squirrel-cage fan, and then blows across the cylinders to keep them cool, especially when the helicopter is hovering and there is no airflow from forward flight.
Once the engine has started, the pilot activates the ‘Drive-Engagement’ system via a switch on the instrument panel. There are a few different belt tensioning systems on piston helicopters but they all do the same job.
The system will then begin to tighten the v-belts, either by activating a motor and gearbox to push the two pulleys away from each other, thus tightening the v-belts, or by an electric linear actuator that moves an idler pulley and pulls the v-belts tight.
