The embodiment of the invention provides a reentry vehicle head repeatable jet flow thermal protection device and a control method thereof. The thermal protection device comprises a load cabin, wherein a gas collecting bottle and a first electromagnetic valve communicated with the gas collecting bottle are arranged in the load cabin; the protection assembly comprises a heat protection part arranged at the head of the load cabin, the heat protection part is provided with a gas inlet and outlet, the gas inlet and outlet is communicated with the first electromagnetic valve, and when the air pressure in the gas collection bottle is larger than the external air pressure, the gas collection bottle is used for absorbing external gas from the gas inlet and outlet for storage; and when the air pressure in the gas collection bottle is smaller than the external air pressure, the gas collection bottle is used for spraying out the stored gas through the gas inlet and outlet. According to the embodiment of the invention, the collected gas is used as a jet flow releasing working medium to perform thermal protection on the head of the aircraft, and the gas collecting and releasing process can be repeatedly used, can be suitable for various ballistic modes, and has better maneuverability.
