Detailed turbine aero design is ready

Despite coronavirus attack, the design progresses. The aerodynamics of the 250kW turbine is ready and can be considered frozen. All the latest trends of microturbine have been incorporated including:

  • supersonic guide vanes optimized for oblique shock control
  • very high expansion ratio
  • swept 3D airfoil profile

Volute has been designed not only to provide a proper swirl but also additionally strengthened to act as a containment shield in case of impeller burst.

Depending on subsequent heat transfer studies an additional thermal barrier ceramic coating may be introduced.

The isentropic T-S efficiency is 90%
