The embodiment of the invention provides a thermal protection structure of an aircraft and the aircraft, and relates to the technical field of thermal protection structures of aircrafts, the thermal protection structure of the aircraft comprises a shell, a storage unit and a control assembly, the front end of the shell is provided with a first air nozzle, and the side wall of the rear end of the shell is internally provided with at least one cooling medium channel; each cooling medium channel is connected with a conveying mechanism for storing a cooling medium in the aircraft, the storage unit is arranged in an inner cavity of the shell and connected with the corresponding cooling medium channel, and the control assembly is connected with the storage unit and the first air jet opening and used for controlling the air jet opening when the temperature of the outer surface of the shell reaches the preset temperature. And the control storage unit is communicated with the first air nozzle. In the embodiment of the invention, the cooling medium is gasified and reversely jetted on the outer surface of the shell after heat exchange in the cooling medium channel to form a protective barrier, so that efficient thermal protection of the aircraft shell is realized, the thermal stress in a high-temperature environment is remarkably reduced, and the safety of an aircraft is improved.
