AI Technical Summary
Existing technologies make it difficult to implement high-voltage direct current electric propulsion systems for distributed electric propulsion aircraft in engineering applications, especially in low-power centralized electric propulsion systems for general aviation, where they cannot meet the requirements of high-voltage direct current electric propulsion systems for distributed electric propulsion aircraft.
A high-voltage direct current electric propulsion system suitable for distributed electric propulsion aircraft was designed, including symmetrically distributed channels, busbars, battery packs, contactors, propulsion motors and propellers, etc. Power conversion and non-similar redundancy control are realized through the system control unit to ensure reliable power supply to the propulsion motor.
It enables automatic power supply conversion in a distributed electric propulsion system, ensuring reliable power supply to the propulsion motor and improving flight safety and overall system efficiency.
