Our research has redesigned the traditional fuel-driven propulsion system to include pure electric and hybrid electric modes.

The on-board electric power system is based on a novel architecture with superior coordination and enhanced stability. The acoustic noise of the vehicle is significantly reduced. The pure electric (whisper) mode offers extreme reduction and optional reshaping of acoustic signatures.

Competitive advantage

  • Priority of electric power over fuel power (the latter is engaged only when electricity is not sufficient)
  • Capability to charge batteries from land-based electricity outlet (access to cheap power)
  • Wide range of propulsion speeds, from very slow to very fast
  • Modular design with energy efficiency and weight distribution advantages
  • Electric motors and power electronic drives capable of shaping noise signatures

Successful applications of research

  • Hybrid electric boat for water police
  • Electric power system for More Electric Aircraft
