Gas Turbine

Basics

• A Brayton cycle ( Jet Engine ) Optimized for Rotary Power Production rather than Thrust
• Can be used for Propulsion ( Turboprop / Turboshaft ) or for pumping fluids (Turbine Driven Pumps in Flood Control or Turbine Driven Pumps in Oil and Natural Gas Extraction + Refining), or for Electrical Generation
• They have the Advantage of Energy Efficiency*, Reduced Part Count , and High Power Density
  • This comes at the cost of increased design (ie not finished device, but the planning / design process / modeling) complexity, and Precision Required (See Turbine Balancing )
• They can be "Fuel Agnostic" to an Extent, however anything with a high Ash Content should be avoided due to the issue of Abrasive Turbine Wear

• Micropower / PowerMEMS (These tend to use Rotary Engines or Gas Turbines due to lower part count and high power density, although Solid Oxide Fuel Cells seem to have made this research slow down due to simplicity (despite needing Catalysts consisting of Rare Earth Metals etc)
• Combined Cycle Engines tend to use a Gas Turbine + Steam Turbine (Or Recently Even a Supercritical CO2 Turbine !), and that is one of the most common modern thermal power plants, especially since they work well as Peaker Plants
