Rockwell made the Excalibur announcement last week at the AUVSI Unmanned Systems show in Washington. Designing avionics systems for unmanned platforms is much less complicated than designing them for manned cockpits because it removes the complicated human machine interface, says Dr. David Vos, senior director of Unmanned Airborne Systems and Control Technologies for Rockwell Collins. Not having the human interface also cuts down on development time and costs, he adds. The Excalibur used the Athena 511 small form factor flight control and navigation system during a flight test to autonomously take off, execute heading control test points, and land, according to a Rockwell Collins release. Additional flight tests with increasingly longer durations and more complex flight profiles are planned later this year. The Rockwell Collins Athena 411 will be part of the SnowGoose upgrade program, Vos says.
The Athena 511 is a member of the Rockwell Collins Athena product line of flight control, inertial navigation systems, GPS, air data, attitude, heading, reference system with well over 300,000 operational flight hours. Some of the Athena technology is also being used in next-generation business jets for navigation and sensing, Vos notes. The sensors are integrated into a single package designed to operate in demanding temperature, shock, and vibration environments. The compact package delivers a simpler avionics architecture and facilitates easier installation and maintenance. The Excalibur vertical take off and landing (VTOL) UAS was developed under a contract with the U.S. Army’s Aviation Technology Directorate and flight tested at the Aberdeen Proving Grounds in Maryland earlier this summer. Excalibur is a revolutionary hybrid electric-powered UAS designed to carry small precision munitions to support forward deployed units requiring strike capability. The SnowGoose autonomously delivers as much as 575 pounds of cargo to as many as six individual locations. The UAV can be ground-launched from a truck or trailer, or air-launched directly from a C-130 or C-17 aircraft.
