hy-generation unveils a self-adjusting electric boat propeller without an axis

french start-up hy-generation has unveiled a new type of electric thruster, equipped with patented self-adjusting blades that improve the performance (thrust and speed) and autonomy of ships. dubbed the electro propulsion PM5kW, this top class electric thruster has been designed essentially for OEM and electric project conversion, suitable for licenseless navigation.

developed to meet the need for expertise and engineering on technologies that profoundly change the energy landscape: fuel cells and hydrogen, hy-generation integrates the latest practices in permanent magnet electric motors with the patented self-adjustable blade system to set a new standard in terms of performance and efficiency. after two years of development, the technology has been refined to be adapted to slow, high displacement boats.

the difference between a classic engine and hy-generation’s one is that the classic one has propellers that turn around an axis while on the other one they always turn, but inside a nozzle. a nozzle is a duct of variable cross-section placed on the rear of an engine producing hot combustion gases which transform the thermal energy into kinetic energy.

‘we have done everything to optimize performance and energy efficiency. when we look at a classic propeller, we see that the axis creates a hydrodynamic disturbance. the circumferential propulsion is more efficient,’ explains rémi champeaux founder of hy-generation.
