High Revolution Jet Turbine

Hi Thingiverse,

**here is my Jet Turbine Project.**
This is a hand operated high revolution compressor turbine blowing through a chopper ring thus generating pressure waves..

The design consists of a Modular High Ratio Step Up Transmission and a Fan/Chopper Stage.

My own challenge for this project is to get the biggest Step Up Transmission Ratio as possible!

**The key to success is all about friction, strength and balance:**
- lower friction -> higher possible StepUpRatio -> higher rpm
- get the tolerances right (gear play)
- strength to withstand high input torque to overcome all the friction.
- strong muscles, good grip
- well balanced turbine and drive shaft to avoid extreme wobble (more friction), wear, damage or even total failure from high rpm

Uploaded AddStageV05 with Ratio i=4.71 and i=5.57 and corresponding Carriers

You can stack..
MainStage4.71 + MainStageCarrier4.71
AddStage5.57 + AddStageCarrier5.57
AddStage4.71 + Handle4.71
..or..
MainStage4.71 + MainStageCarrier4.71
AddStage4.71 + AddStageCarrier4.71
AddStage4.71 + Handle4.71

4.71x5.57x4.71 works but is much harder to turn. I think I reach higher rpm with 4.71x4.71x4.71 or maybe I'm just not strong enough. I will test more and measure over the holidays. V05 Stages are compatible with previous V04 prints as long as you use the corresponding V04…
