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\
- Efficiency tends to increase with rpm
- Will a Gearbox be needed, or can direct to generator work? ( Planetary Gearbox most likely )
- 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
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
Commercial/Industrial
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?)
BOM
Phase 1
- A good Scrap Yard run to get turbochargers, and anything else you can find still in working order
- If not get them OTS A Guide Here
