The invention discloses a gas-phase sweating cooling thermal protection system based on self-sustaining channel supply. The gas-phase sweating cooling thermal protection system comprises a gas source supply device and a gas-phase sweating cooling thermal protection device. The gas source supply device comprises a self-sustaining channel, a gas storage tank, a regeneration cooling channel and a spray cooling assembly; the gas-phase sweating cooling thermal protection device comprises a porous medium layer and a cooling working medium supply channel; the self-sustaining channel comprises a front section part and a rear section part and is used for sucking high-speed incoming flow and conveying the high-speed incoming flow to the gas storage tank; the regeneration cooling channel is arranged on the periphery of the front section part and is used for cooling high-speed incoming flow for the first time; the spray cooling assembly comprises a plurality of spray coolers arranged in the rear section part and is used for cooling the high-speed incoming flow for the second time; the porous medium layer is arranged on the outer surface of the aircraft. The device is applied to the technical field of thermal protection of high-speed aircrafts, the mass of the coolant carried by the aircrafts is greatly reduced, and the cruising ability of the aircrafts is improved while the cooling efficiency is guaranteed.
