Provided is an ultra-high temperature thrust flow actuator to minimize friction and leakage, capable of minimizing the friction coefficient between a shutter and a high-pressure chamber, when a jamming occurs by thermal expansion at high temperatures between the rotating body and the housing, in structures like thrust devices used for controlling the attitude of spacecraft, such as satellites, or weapons, such as missiles, in aerospace and flight environments. The ultra-high temperature thrust flow actuator includes: a driving unit configured to open and close a jetting port of a flow jetting unit ejecting high-temperature high-pressure gas, thereby controlling a flow of the high-temperature high-pressure gas; and a plurality of protruding units, each protruding outwardly from the driving unit.
