The invention discloses an active and passive combined thermal protection system for an aircraft. The system comprises a pneumatic heat conduction part, an aircraft shell, a local active cooling part, a main cold supply source, a heat exchange conveying pipe network, a secondary cold supply source, a bypass conveying pipe network, a local cooling conveying pipe network and a measurement control system. The pneumatic heat conduction part is arranged at the front end of the aircraft shell; the main cold supply source and the measurement control system are arranged in the aircraft shell; the main cold supply source, the heat exchanger of the pneumatic heat conduction component and the secondary cold supply source are communicated through a heat exchange conveying pipe network; a local active cooling part is arranged in the middle of the aircraft shell; the main cold supply source is communicated with the local active cooling part through the bypass conveying pipe network and the local cooling conveying pipe network; and the secondary cold supply source is communicated with the local active cooling part through a local cooling conveying pipe network. According to the system, flexible combined thermal protection of active and passive combination in space and active and passive switching in time is adopted, and the global optimal comprehensive thermal protection efficiency of the long-time high-speed near space aircraft is achieved.
