FUNDAMENTALS OF GAS TURBINE ENGINES
FUNDAMENTALS OF GAS TURBINE ENGINES INTRODUCTION The gas turbine is an internal combustion engine that uses air as the working fluid. The engine extracts chemical energy from fuel and converts it to mechanical energy using the gaseous energy of the working fluid (air) to drive the engine and propeller, which, in turn, propel the airplane.

Factcheck: How often do wind turbines break? - Unearthed
Jan 15, 2015 · The how and why of the fallen turbine at County Tyrone – one of eight at the Screggagh wind farm – is being formally investigated by German manufacturer Nordex. It's suspected that there was a break with the machine's brakes, that the blades then span so fast the head became unhinged, and ultimately the whole thing came crashing down.

Broken turbine wheel + The turbine wheel is driven by the outgoing exhaust gases and transfers this energy to the impeller via a shaft. If a problem occurs here, the turbocharger no longer achieves the necessary speed and the boost pressure falls. The most common type of damage to the turbine wheel is caused by foreign objects.

Why not use turbine engines in cars? | Physics Forums
Aug 25, 2015 · cjl said: Turbine engines aren't used for a number of reasons. 1) Their idle and low-load fuel efficiency is appalling. Most car engines spend the majority of their lives far from peak power output, so turbines' high efficiency at high load wouldn't really help them here. 2) Throttle response.
