Hybrid Power System (P1P3) on eVTOL application

This white paper outlines a sophisticated thermal management system (TMS) designed for the P13 hybrid-electric aircraft, framing heat control as a strategic performance enabler rather than a secondary function. The text identifies a critical "ice and fire" dilemma, where the system must simultaneously cool high-temperature engines and sensitive low-temperature batteries, particularly during high-stress hover phases when natural airflow is unavailable. To resolve these conflicting demands, the document proposes a tri-loop topology using dielectric fluids to ensure electrical safety and prevent catastrophic short circuits in the high-voltage powertrain. Beyond basic cooling, the paper details intelligent control features like battery pre-conditioning and waste heat recovery to maximize efficiency and regulatory compliance with global aviation standards. Ultimately, this engineering framework serves as a safety-centric foundation meant to ensure the commercial and operational viability of next-generation urban air mobility.
