AI Technical Summary
Existing aircraft electrical architectures are primarily adapted for high-voltage direct current (HVDC) and do not efficiently utilize alternating current (AC) power from turbomachine shafts for propulsion and load distribution, lacking optimal power utilization and safety in hybrid propulsion systems.
An improved hybrid propulsion architecture that includes AC aircraft electrical networks with reversible AC/AC electrical power conversion modules, allowing power sharing and injection on high-pressure and low-pressure turboshaft engine shafts, and utilizing electronic control systems for safe and efficient power distribution.
Enables optimal use of turbomachine shaft power for propulsion needs, ensures functional availability, and operational safety while maintaining an aircraft network in AC, allowing for efficient power sharing and converter sharing scenarios.
