Abstract
The invention is a method for engaging the drogue of a hose and drogue refueling system with the probe of a receiver aircraft for aerial refueling from a tanker aircraft. The tanker aircraft and receiver aircraft approximately match speed and direction, with the probe of the receiver aircraft maintained at approximately a first predetermined distance behind the tanker aircraft. The hose and drogue are extended rearward from the tanker aircraft so that the drogue is positioned at a second predetermined distance (shorter than the first predetermined distance) behind the tanker aircraft. The drogue and probe are orthogonally aligned with each other, and the hose is extended back beyond the second predetermined distance so that the drogue moves away from the tanker aircraft to and into engagement with the probe. The force of the air stream on the drogue is sufficient to provide for secure engagement of the drogue with the probe.
