DARPA's air-steered X-65 jet heads into production with goal of flying by 2025


Re: Wing-Warping

Some aircraft do, indeed have linked yaw and roll control - Mooney aircraft feature a link between rudder and ailerons.

There are others. I believe Airbus has a mode where a link can be activated, but I may be mistaken.


Re: What could go wrong...

Actually they require increased lift for takeoff, and the combination of lift and increased drag for the landing. On landing, this allows a steeper descent profile with control.

You are confusing how it is accomplished with what is required. (The same mistake users make when describing software requirements. They tend to present the solution instead of describing the actual problem)

If this system handles the requirements via a different mechanism, then you don’t need the flaps. We have no way of knowing this from the article.

Flaps increase lift, with the penalty of increased drag - especially at large flap deployments. The drag is useful in landing, not so much for takeoffs.

Overtake the debris from behind, so the relative speeds are quite low. The nets would detach when sufficiently full, and have retro boosters to form a de-orbit burn.

Whatever the outcome is, if we figure out the universe, it will be replaced by something even more bizarre. There is much speculation that this has happened more than once.

Best attribution I came across in some code in a large project: this routine is very loosely adapted from “the sound of music”

I left that comment block in place as I re-factored the code to run on a different platform.

US Space Development Agency invests $1.3b in missile tracking satellites


the mix of missiles has changed since the cold war

I suspect the types of missiles and the means of tracking them is far more complex than the old cold war era systems of ICBMS. Cruise missiles, medium range missiles, hypersonic missiles, stealth technologies, are all (relatively) new threats to deal with. I would guess the older sensors aren't up to the task, plus the need to integrate the information into the "battle net" in real time is a factor as well.

The modern battlefield is basically a giant mesh network of sensors and and weapons. The pace at which technology evolves will result in more and more frequent updates to satellites and ground based monitoring platforms.

Re: Paint it orange and yellow . . .

Actually there are a number of uses:

including inspecting fence lines, runways, towers, tank farms (the kind that hold fluids, not the kind that run around on tracks), security - one or two soldiers could patrol a larger area than on foot, and probably quieter than in a Humvee. From an elevated position, you can see a far greater area.

There are locations with antennas on mountain tops - quick and cheaper way to get to them in a timely fashion. I can see the operating cost per hour being a lot cheaper than using a helicopter.

and that's just off the top of my head, limited in capacity though it may be.
