Design Features

Gas generator & free power turbine configuration

  • Robust and efficient two-shaft design permits optimal operating conditions for individual components
  • Fluid coupled free power turbine allows direct-drive of alternator/generator – no gearboxes

Advanced turbomachinery

  • Centrifugal compressor operates at 175,000 rpm, producing a single-stage pressure ratio exceeding 4:1
  • Radial-inflow gas generator turbine is rugged and efficient, operating at inlet temperatures above 1600 F
  • Axial free power turbine operates at 80,000 rpm to match alternator/generator design requirements

Durable & efficient ball bearing system

  • Cartridge ball bearings with squeeze film dampers have been proven in turbocharger applications
  • Combined lubrication and cooling system improves life

Compact & reliable combustor

  • Radial entry air swirl stabilized combustion zone produces high efficiency and reliable performance over all operating conditions
  • High pressure fuel injection (>1,500 psi) for clean, low maintenance operation
  • Modular design for quick adaptation to different fuel types (JP8, JET-A, ethanol, gasoline, gaseous fuels)

Advanced materials & manufacturing technologies

  • Materials used in critical components include ultra-high strength aluminum, titanium, and heat-resistant superalloys
  • State-of-the-art manufacturing techniques include 5-axis CNC machining, DMLS, and rapid casting
