Abstract: The arrangement serves to control the structural dynamic response characteristic of a booster rocket, which is provided with a propulsion engine as well as a payload. The booster rocket includes at least one control unit as well as at least one control element for altering a flight path perpendicularly to a lengthwise axis of the rocket. The control element is embodied as a rotatably supported control fin, arranged at a lateral side area of the booster rocket. Sensors are provided to measure lateral wind loads. An adjustment element is connected to the control fin and is adjusted by the control unit in such a manner that measured values provided by the wind sensors are converted into position adjustments of the control fin for compensating crosswise forces.
