PROBLEM TO BE SOLVED: To reduce dependency on jet air flow injection for attitude control of a vehicle body and reduce a loading amount of propellant by positively utilizing jet interaction effects to increase a vehicle body payload and downsize the vehicle body.SOLUTION: Jet interaction actuators 5A, 5B are designed to control an attitude of an atmospheric re-entry vehicle by utilizing jet interaction effects, and the actuator comprises: a wall body 6 that rises from a pressure-receiving surface 3, against which supersonic air current hits, of a vehicle body 2 of the atmospheric re-entry vehicle; and a jet injection nozzle 7 which is formed at a position at least on one side of the wall body 6 with a predetermined distance L from the top portion (bottom surface 6b) of the wall body 6, and injects jet air flow J in a direction orthogonal to a surface direction of a side surface 6a of the wall body 6. |
