DroneWatch: Hier tankt die Drohne, autonom

US Navy's X-47B, AV-2, Bureau # 168064, of Air Test and Evaluation Squadron Two Three (VX-23) successfully complete Air-to-Air Refueling (AAR) with the K-707 Omega Tanker over the Chesapeake Bay on 22 April 2015.  VX-23 is part of the Naval Test Wing Atlantic in Naval Air Station Patuxent River, MD.  The Mission Operators of the X-47B are Northrop Grumman Corporation’s Mr. Corey Lazare and Mr. Dave Fulton. Pilots of the Omega Aerial Refueling Services are Mr. Tom Straiton and Mr. Dennis Warren. (U.S. Navy Photo by Liz Wolter)

Über die Experimentaldrohne der U.S. Navy, die X-47B, war auch hier bei Augen geradeaus! schon einiges zu lesen – zum Beispiel über ihre autonome Landung auf einem Flugzeugträger. Jetzt folgte ein logischer nächster Schritt: Das unbemannte Flugzeug dockte ebenfalls autonom an einen Tanker an und übernahm im Flug Treibstoff. Das Video dazu:

Und aus der Mitteilung des Naval Air Systems Command:

The X-47B successfully conducted the first ever Autonomous Aerial Refueling (AAR) of an unmanned aircraft April 22, completing the final test objective under the Navy’s Unmanned Combat Air System demonstration program.
While flying off the coast of Maryland and Virginia in the Atlantic Test Ranges, the X-47B connected to an Omega K-707 tanker aircraft and received over 4,000 pounds of fuel using the Navy’s probe-and-drogue method.
“What we accomplished today demonstrates a significant, groundbreaking step forward for the Navy,“ said Capt. Beau Duarte, the Navy’s Unmanned Carrier Aviation program manager. “The ability to autonomously transfer and receive fuel in flight will increase the range and flexibility of future unmanned aircraft platforms, ultimately extending carrier power projection.“
During the test, the X-47B exchanged refueling messages with a government-designed Refueling Interface System (RIS) aboard the tanker. The aircraft autonomously maneuvered its fixed refueling probe into the tanker’s drogue, also known as the basket, the same way a Navy pilot would refuel a manned aircraft.
“In manned platforms, aerial refueling is a challenging maneuver because of the precision required by the pilot to engage the basket,” Duarte said. “Adding an autonomous functionality creates another layer of complexity.“
This testing helps solidify the concept that future unmanned aircraft can perform standard missions like aerial refueling and operate seamlessly with manned aircraft as part of the Carrier Air Wing, he said.

Auch wenn alles offensichtlich nach Plan geht: es scheint schneller zu gehen, als es sich viele vorstellen können.

Ein interessantes Detail am Rande: Aus der Bildunterschrift zum Foto oben geht hervor, dass der Betankungs-Test nur von zivilen Contractors durchgeführt wurde, ohne einen einzigen Soldaten dabei…
