Abstract: A drogue is provided having a projected area associated with an aerodynamic drag-generating arrangement of the drogue. The drag generated by the drogue is a function of the projected area, and the drogue has a mechanism for controlling the drag generated by the drogue with respect to changes in airflow dynamic pressure by adjusting said projected area. The mechanism comprises control members for driving said adjustment, the control members being configured for providing a driving force for driving said adjustment that is generated by and related to the airflow dynamic pressure. An in-flight refueling system having such a drogue, and a method for operating a drogue are also provided.
