Quiet, Efficient, and Economical Power for Electric Aircraft

Moduar/Scalable - use one genset for smaller vehicles, two for larger vehicles

Broadly Applicable - suitable for UAM eVTOL, eSTOL, eCTOL


Quiet - much quieter than turbines and turbine-hybrids


Lowest Direct Operating Costs - compared to turbine-hybrids and battery-electric 

Flexible - multiple potential operating modes using optional thru-shaft:  mechanical shaft power on/off, electrical power on/off, burst power from battery to boost mechanical shaft power

Batteries alone can't meet the mission?

  • 5-7X higher energy density than batteries

    • Transformational range while meeting energy reserve requirements​

  • Up to 12X faster refuel/recharge

    • More flights per day = more revenue​

  • No charging infrastructure required

Turbine options too loud or too thirsty?

  • 40% better fuel economy for lower DOC and carbon emissions

  • Available with noise mitigation below 70 dB at 100 ft or less

  • Built around a certified engine and air cooling, familiar aerospace technology
