Technology Description:

GE Research will develop a safe, lightweight, and altitude-capable megawatt power cable system with electromagnetic interference shielding capability for large aircraft. The proposed 10 MW cable system is expected to achieve ten times greater power density than conventional technology without degradation by partial discharge and is fire safe and oil resistant. This cable system will enable all-electric distributed propulsors for future large aircraft to achieve zero emissions by using aluminum conductors insulated and cooled with CO2, both of which are readily available, manufacturable materials. The proposed cable technology can also be used in other applications requiring high cable power density with a relatively small footprint including electric ships, submarines, and offshore wind turbine platforms.
