A Unique Micro Gas Turbine at ONERA (10W – 100W)

Applications

Geometry and calculations  
Streamlines in the turbine  

 > Aerospace

• Propulsion of micro UAV.

 > Other Industries

• Independent power supply, in particular for portable systems, 10W-100W range.
• Energy distributed to drive actuators.
• Cooling of electronic circuits.

Advantages

• High power: weight ratio.
• Reduced size (size of a button!).
• Safe, easy, portable power supply.

Description

• Conceive and control the micro combustion and heat fluxes with the walls.
• Gas bearings at high speed, great stiffness and low fuel consumption of energy.
• Design micro machines of the type MEMS, as much as being made that can, accordingly developing methods of major engraving and sealing of the layers of materials like Si or Sic.
• Micro electric engine/generator at high speed and high output in hot environment.
• New gas micro turbine with high performances, starting from the original study by Professor T. Nagashima.
