The invention discloses a flight and energy management cooperative control platform of a distributed electric aircraft. The flight and energy management cooperative control platform comprises an environment monitoring unit, a flight profile selection unit, a flight control unit and an energy management unit, the environment monitoring unit calculates an air density parameter in the current environment and sends the environment temperature to the energy management unit, and the energy management unit responds to the influence of different temperatures on the battery; the flight profile unit selects an aircraft dynamics model according to the input of a flight profile, and determines theoretical propulsion demand power according to the profile; the flight control unit calculates a final actual thrust demand and sends the final actual thrust demand to the energy management unit to serve as the input of the energy management unit; and the energy management unit sets an optimization target, selects a constraint and energy management strategy to perform energy flow scheduling, and performs power control to stabilize the bus voltage. According to the invention, the defect of unclear labor division of the flight control unit and the EMS in the electric aircraft is overcome, and the real-time performance and the energy utilization rate of the energy management system are improved.
