Autonomous Damage Control System

Rockwell Collins has just picked up the third phase of a damage tolerance contract by the Defense Advanced Research Projects Agency (DARPA). Under the contract, Rockwell Collins will demonstrate completely autonomous takeoff, recovery from extreme damage and failure, and autonomous landing of an unmanned subscale F/A-18. Additional flight tests will be conducted on an operational Unmanned Aircraft System (UAS).

Over the course of approximately 15 months, Rockwell Collins will demonstrate its full Damage Tolerance and advanced controls capabilities.
Flight tests will demonstrate increasing damage to both the subscale F/A-18 and an operational UAS, including the failure of control surfaces and parts of the wing, as well as loss of vertical and horizontal tail surfaces. The flight tests will also include an "engine-out" condition followed by automatic adaptive recovery and emergency autoland.

​

"In addition to demonstrating increased reliability of unmanned aircraft, the damage tolerance work we are doing with DARPA goes a long way in facilitating evolving applications for UAS and the safe coexistence of manned and unmanned aircraft in common airspace," said Dr. David Vos, Senior Director of Control Technologies for Rockwell Collins. "Unmanned aircraft reliability in the battlespace will ensure that U.S. and Allied forces receive real-time high quality Intelligence, Surveillance and Reconnaissance (ISR) data."

​

"This next phase of the Damage Tolerance program will demonstrate that technology exists to reliably control UAS operating under the most challenging conditions such as extreme damage, upset or failure," said DARPA Program Manager James McCormick.

​

Damage Tolerance Phase III follows Phases I and II, which were completed in April 2008. In Phase II, the technology demonstrated an aircraft could survive catastrophic wing damage, recover its baseline performance, and safely land - all autonomously.


The final flight test for Phase II, was an eye opener in that 60 percent of a wing was ejected and the adaptive controls were turned off and on -- successfully.

I posted this a while back. The thing I really find interesting is how it doesn't actually use any preset flight envelope but retools the control inputs in real time to attain stable flight.

One of my friends worked Dryden one summer back in college and this seems to be the culmination of what he worked on. Back then, he said that all he did all summer long was to crash F-18 into each other. Pretty impressive to see that people can actually design software that thinks quick enough for that kind of flight envelope.

Reminds me of the Israeli F-15 and the two Marine F/A-18s.

Maybe that viral video of the pilot landing the Extra wing a wing missing isn't fake after all!

No doubt. Still one has to wonder how he was able to reconfigure the push rods and pulleys to get independent movement of the controls. :nana2: Regardless, some real fast thinking on his part.

All of them were nice saves. Just happy that wasn't me flying them at the time. I remember seeing the History Channel on the F-15 and the pilot just said that he saw fuel leaking out the side of the aircraft. Didn't have a clue that the wing was gone until he had the aircraft stopped on the runway.

Peekaboo, I'm not here! anic:

It's nice to know that there are some really good sticks out there.
