ENERGY-EFFICIENT HYBRID ELECTRIC VEHICLES WITH ACOUSTIC SIGNATURE SUPPRESSION/VARIATION

Our research has redesigned the traditional fuel-driven system to include pure electric and hybrid electric modes. The on-board electric power system is based on a novel architecture with superior IMPACT coordination and enhanced stability. The • Reduction of running costs and CO2 emissions acoustic noise of the vehicle is significantly • Increased efficiency reduced. The pure electric (whisper) mode • Improved reliability and prolonged service life offers extreme reduction and optional • Improved balance and stability reshaping of acoustic signatures. • Reduced acoustic noise and electromagnetic interference • Acoustic silencing and camouflage

COMPETITIVE ADVANTAGE CAPABILITIES AND FACILITIES • Priority of electric power over fuel power (the latter • Prototype 22-feet hybrid (river trials in 2020) is engaged only when is not sufficient) • Laboratory model of electric power system for boat • Capability to charge batteries from land-based • Laboratory model of electric power system for aircraft electricity outlet (access to cheap power) • Capability to adapt to specific application requirements • Wide range of propulsion speeds, from very slow to very fast • Ongoing collaboration with equipment manufacturers • 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 for water police • Electric power system for More
