Open Source Gas Turbine

Basics

• Essentially an Open Source Turboshaft Aircraft Engine that is used for stationary rotary motion generation
• It is relitively to throw together a turbojet. Our real challenge will be making it efficient and perhaps compact
• Should be able to use liquid fuels and gaseous fuels
• Liquid Fuels:
  • Ethanol
  • Methanol
  • Biodiesel
  • Bio-Jet Fuel
  • Dimethyl Ether
  • Really need to check what can and can't work NEEDS MORE RESEARCH
• Gaseous Fuels
  • Hydroge
  • RNG

Used For

• Medium to Large Scale Power Generators
• Large Vehicles
• Smaller home scale version?
• Hydrogen Cooled Gas Turbine for INTENSE industrial use? (Probably need a full on engineer for that one)

Industry Standards

Portable

• Goofy concept, but one such device was created the Dynajet Generator
• RC Turbojets/Turboshafts Exist

Home-Small Scale Commercial/Industrial

• 100kw-1Mw seems to be the common designs

Existing Open Source Designs

• Colin Furze makes all sorts of (albeit inefficient) jets
• Tech Ingredients has made some "lab scale" turbojets, and edfs, may one day do a turbogenerator

Minimum Viable Product

• Scaleable from commercial grade generators, and things like large commercial groundcraft/watercraft, all the way to industrial grade generators

Basic Design

Phase 1

• Automotive Turbocharger based compressor and expander
• Metal tube for combustion chamber
• Tech Ingredients this is essentially what it will be
• Question is how to couple this to an electric generator? (Or a Variable Piston Pump for hydraulic fluid?)
• Electric Fan Starter, or is there a way to use the generator stage for this (in reverse?)

Phase 2

• 5 Axis CNC Mill or somthing similarr for custom turbine blades
• Fuel Injector with small holes via thrown together EDM (needle/thin metal rod?)
