High Power Density Cost-Effective MV DC Aircraft Cable
08/02/2021 - 07/31/2022
To make the power density of electric aircraft closer to conventional aircraft, an electric power system (EPS) with high power delivery and low system mass is necessary. As an essential component of aircraft EPS, cables are necessary to transmit power from one node to another. Virginia Tech will develop a high-power density, cost-effective ±5 kV cable for twin-aisle all-electric aircraft. Innovations include conductors with increased current-carrying capacity; a multilayer, multifunctional insulation system made of exceptionally high thermal conductivity materials; and a new insulation solution for higher voltages with superior mechanical strength and electrical reliability. Designed for DC voltage, the new insulator will allow fewer partial discharge events and provide improved electromagnetic interference protection.
