Note:
An electric power system (EPS) with high power delivery and low system mass is required for all electric aircraft (AEA). Cables are an essential component of this future EPS. One way to reduce the weight of cables is to operate at a higher voltage and therefore the goal of this project is to develop a power-dense, cost-effective 10 kVdc (±5 kV) cable for twin-aisle AEA that can safely operate in high-altitude, low pressure environments. Expected innovations and impacts from this research include AAC/TW conductors with increased ampacity for the cable core as well as a multilayer, multifunctional insulation system that contains exceptionally high thermal conductivity aluminum nitride (AlN) materials and a novel insulation material for use with higher voltages that has the best combination of superior mechanical strength and electrical reliability. These innovations will be designed for a DC voltage cable and lead to considerable reduction in partial discharges. The cable will be optimized for 10 kVdc (±5 kV), a nominal power of 10 MW, very low partial discharges at an altitude/pressure of 12.2 km/18.8 kPa, and excellent electromagnetic interference and compatibility (EMI and EMC) performance. The cable will transfer maximum power in an innovative DC EPS optimally designed to make NASA’s N3-X become AEA.
