The Nordin Jet Engine

The Nordin Jet Engine as a jet turbine with a single moving part. The whole jet revolves around an axis including the shell.  Fuel is either fed through the axis and through a centrifugal pump or "inhaled" by the jet from the front in the form of gases.

Advantages:

1. Easy to manufacture (even 3d print)
2. Low friction and long life
3. 100% tight between blades and casing
4. strong (since turbine blades and casing form a single object)

Other variant: fuel acts as diffusor:
