This invention discloses a plug-in independent power supply hybrid power system for aircraft, which can be installed in situ without altering the original aircraft's core structure. The system employs an external independent power battery module, a small-power engine generator, and a small battery module to form a "three-level independent redundant power architecture," with each unit's power supply circuit electrically isolated from the others. The external independent power battery only charges on the ground and discharges unidirectionally during flight, without energy recovery or reverse charging. It only replaces all functions of the flight control system and electronic control system when the engine and small battery fail. The small-power engine does not participate in takeoff and climb, but is dedicated to cruise power supply. The small battery is responsible for powering the flight control system, electronic control system, and engine starter, sharing a high-voltage DC bus with the generator to achieve bus voltage stabilization and short-term power compensation. Ground charging simultaneously performs a full system self-check. When the battery power is insufficient or the test fails, there is no manual bypass, and the electronic control system is forcibly locked, prohibiting engine starting and ensuring absolute flight safety.
