For electric aircraft to be commercially feasible, substantial improvements need to be made to electric propulsion system technology. Today, best-in-class motors and inverters have a combined power density of 3-4 kW/kg. ARPA-E has determined that for a Boeing 737 to complete a typical five hour flight, the propulsion system must be >12 kW/kg continuous.
We have the solution.
At 12 kW/kg continuous, the HPDM exceeds ARPA-E’s requirements and is at least 3X better than current systems. It is a step change in electric propulsion technology and removes one of the main barriers blocking widespread commercialization of electric aircraft.
