Fighting Fire From the Sky

exceed writes: "Yahoo! News has an article on an unmanned robotic airplane that is able to circle around wild fires for up to 24 hours, sending data and images back down to earth via satellite. The Altus II, created by NASA, employs cutting edge technology usually seen in military aircraft, giving fire officials a real-time view of fires that can burn over hundreds of thousands of acres. The plane could map dozens of fires and topographical features in a day, never endangering a pilot."

  34. Anti-fire bomb! by Anonymous Coward · · Score: 0

    Why don't they invent instead an anti-fire napalm type bomb!? A bomb that is surrounded with some uninflammable substance like foam with some explosives inside, the explosion would consume the surrounding oxygen in the area and the foam would be instantaniously spread across a large area also, it will be perfect for high intensity fires since it could be dropped from an helicopter or airplane.

    Why? why doesn't it exist yet?!

    1. Re:Anti-fire bomb! by SEWilco · · Score: 1
      Great design. Let's see.. to snuff a forest fire that's five miles in diameter you'd need about ...um...

      The Hiroshima bomb destroyed most buildings within a mile, so that's a two-mile diameter, so you'd need about five Hiroshima-sized bombs to have a significant blast effect over an area five miles across. That's 15 kilotons, so you'd need 15 x 5 = 75 kilotons, or 75,000 tons, or 150,000 pounds of conventional explosive. (Yeah, it might not snuff the fire, but the updraft under the mushroom cloud will tend to suck the fire inward and slow its outward travel -- ignoring the effect of flying flaming objects)

      Maybe five aircraft would be more practical, but let's see if one can do it. It looks like a 707 or KC-135 can handle 150,000 pounds and have capacity for some fuel weight. I don't know what the safety requirements would be to allow unmanned flight for civilian use of something like that.

      Now, about the foam.. The area of a circle 2.5 miles in diameter is 547 million square feet (pi * r^2), so if you're going to cover just the surface (not trying to cover all branches on trees) to a depth of one foot, you need 547 million cubic feet of foam.

      One Goodyear Blimp has 202,700 cubic feet of helium, so we'll assume it can hold that much foam.

      So, fill a 707 with explosives and strap around it 2,700 Goodyear Blimps full of foam. Probably want to add some more, as some of the foam will be vaporized by the blast. Well, might be easier to just drop the blimp-sized bags of foam separately. There ya go, it's all designed. The rest is just engineering.

      So, why doesn't it exist yet?

    At one point, the article says:

    The plane is a variant of the Predator unmanned surveillance aircraft manufactured by General Atomics and used by the U.S. Air Force.

    The Predator is unpiloted. Completely, I believe. It flies, lands, and takes off all by itself. I believe it's similar to the Global Hawk, a surveillance plane that can fly an entire recon mission just from one person making two mouse clicks.

    But they also say:

    Wegener said the Altus II, which is controlled by pilots on the ground, still needed to clear a few hurdles

    My own emphasis. Can anyone clarify this? They are calling it a robot plane (which to me suggests an unpiloted plane), but then they say it's remotely piloted (a rather different thing, I thought). My guess as to what it means is that either: a) they're going to make it unpiloted, but haven't yet, or b) It's 'sort of' piloted - it doesn't fly the whole mission by itself, but you have someone giving a good general idea of what to do most of the time.

    Either way, a valuable project. It's through stuff like this that Artificial Intelligence, one of the most hyped up fields of research that ever existed, can have useful, visible products.
