Drones. Everybody loves them, and everybody wants more of them, even if (in many cases) it’s entirely unreasonable. But let’s not get into that. No, instead we’re going to stick with something very reasonable today, and talk about how the U.S. Defense Advanced Research Projects Agency (DARPA) wants someone to build a system with the “ability to launch and recover multiple small unmanned air systems from one or more types of existing large manned aircraft.” Coooool!
Here’s DARPA’s thinking: UAVs are a way to keep human pilots out of danger in military operations. That’s good. Smaller, not crazy expensive UAVs can’t fly very far or very fast or for very long. That’s bad. If you got larger aircraft (like C-130 transports) to launch and recover small UAVs, though, you could potentially get the best of both worlds.
“We want to find ways to make smaller aircraft more effective, and one promising idea is enabling existing large aircraft, with minimal modification, to become ‘aircraft carriers in the sky’,” said Dan Patt, DARPA program manager. “We envision innovative launch and recovery concepts for new UAS designs that would couple with recent advances in small payload design and collaborative technologies.”
The agency envisions a large aircraft that, with minimal modification, could launch and recover multiple small unmanned systems from a standoff distance.
Our guess is that the recovery part is what’s going to be the
hardest most exciting. In addition to the C-130 (which has a minimum speed of about 115 mph), DARPA also suggests that it might be cool to develop something for the B-1B Lancer as well, which has a minimum speed of about 170 mph and looks like this:
The Lancer has reasonably spacious bomb bays underneath, and we’d love to see drones autonomously buzzing in and out of there. But at least initially, we’re guessing that the C-130 will be a bit easier to work with:
At the moment, UAVs that get recovered from moving platforms (like ships) do it by flying headlong into a rope or a net that can capture them by absorbing their momentum. Since the carrier planes won’t be able to hover, it seems likely that recoveries will have to be at speed, so perhaps something like this:
Hopefully, DARPA will have way better ideas than this to choose from. Suggestions are due on 26 November, and DARPA hopes that a full scale flight demonstration might be possible within four years.
