19th Century Airship Technology for Port Security 295

fenimor writes "Airships - known today mainly for advertising flyovers at football games - are the core of a new coastal surveillance system in development for the the U.S. Department of Defense. These stationary platforms 25 times the size of a Goodyear blimp will be equipped with an array of cutting-edge equipment for remote sensing, communications, and risk analysis, providing surveillance coverage over a surface area of 500,000 square miles from an altitude of 70,000 feet."

      There are much cheaper alternatives in the works, such as the High Frequency Surface Wave Radar [drdc-rddc.gc.ca] being developed by Raytheon Canada [raytheon.ca] and Defence Research Development Canada [drdc-rddc.gc.ca].

      The big problem with conventional radar is that it only works in line-of-site, but Raytheon's SWR-503 Surface Wave Radar [raytheon.ca] uses high-frequency radar waves that "wrap" around the curvature of the earth. The system has been proven to detect and track aircraft, surface vessels and icebergs out to 500 km from the shore in a sector of up to 120 degrees. Suspicious objects can be investigated by satellite, surface ship, patrol aircraft or very cheaply & covertly via unmanned drone [dreo.dnd.ca].

      Canada plans to install an array of radar installations along the East Coast in order to provide a seamless picture of all maritime activity occuring in the country's economic zone. Similar research is being carried out in the US, Australia and other countries. This seems like a much more effective use of resources than a massive blimp installation

        You mention Icebergs and maritime activity. But most drug smugler boats are less than 8 feet above water at the top while most icebergs and any ships worth tracking are at least 40 feet at the top. Can the radar work with such a small profile? Also, will it work in high seas? Even normal weather in the north atlantic has at least 8 foot swells when you get out to sea. Will it still work then?

        Small correction: The surface radars in question actually use low frequency "radar waves" (no such thing, it's radio waves). Correctly: the system uses HF RF (HF band RF) which is a considerably lower frequency band than most modern radars operate at. At a guess these HF radar systems will suffer from problems of low resolution, making them less suitable for detection of small targets than an S or X band airborne system would.

        You'd be surprised what you can do with a little knowledge of physics.

        Let's start designing a really good airgun. Or actually describe something which already exists.

        First let's remember that you can only accelerate something via gas pressure to the speed of the gas mollecules themselves. Any faster, and the gas will literally be left behind.

        So we'll want to maximize the velocity of those mollecules. The energy of one of those little buggers depends on temperature. But that's not our ticket. Our ticket is noting that at the same energy (hence temperature) the less mass you have, the more velocity is needed to achive that energy.

        Hence, you'll want a very lightweight gas. Hydrogen or helium will do just nicely. So we'll build a hydrogen gas gun.

        Now to compress the helium. Well, have the airgun's barrel, which is a thin tube. We'll also have a much larger tube with a piston to compress the gas.

        Think: a syringe. We push the piston in the large syringe body, to shoot a tiny sting through the tubular needle. Of course, at a much larger scale.

        We'll also need to push the piston really hard, to create a lot of pressure. An explosion will do that just nicely.

        It's really much like a conventional gun with a twist. Instead of the (relatively) heavy gasses from the explosion directly pushing the projectile, we compress hydrogen with them and the hydrogen pushes the projectile.

        It's a very large device and very much a one shot gun, because reloading it takes ages. As such fairly useless against either ground targets or aircraft. (Against aircraft you really want something which sprays a lot of bullets.)

        It also accelerates a dart to miles per second velocities. Theoretically, you could shoot at a sattellite in low orbit with it, except you would need to aim very very well. However, to punch a hole through a huge stationary blimp, it's perfect.

        It's also low tech. A lot lower tech than rail guns. Any third world country could build one, if they wanted to. Heck, theoretically you could build one in your back yard. (But in practice the police would want to know about all those explosives you're buying.)

        Until now, well, there was no problem for which it would be a solution. Now those blimps are just the problem for it.

      Gravity.

      It has been called an "unforgiving motherfucker" by the walker-bound elderly, but the fact is, only gravity can protect our prescious airships from the terrorists who seek to destroy our way of life.

      Let's suppose you've got a nice powerful 50 cal that fires at 2000 feet per second.

      physics [ucsd.edu] tells us that it'll take 2000 feet per second / 32 feet per second per second = 62.5 seconds to reach it's max height.

      Then we can figure out how high that is with this equation:

      distance = initial speed * time - ( 1/2 ) * acceleration * time^2

      2000 * 62.5 - 0.5 * 32 * 62.5^2
      125000 - 62500
      == 62500

      So your bullet will turn around roughly a mile short of the target. :)

    At 70,000 ft, atmospheric distortion (looking down) because a huge problem. You might be able to have optics that can make out a license plate in theory, but in practice it wouldn't be possible without some seriously adaptive optics.
  • It seems like every few years, someone trots out an idea to use airships for some mission requiring heavy lift or long loiter time (say, roadless logging or maritime sensor platform). After a while, the idea vanishes.

    I've seen a Goodyear blimp flying along the California coast in a strong crosswind. It was barely under control.

    Until such issues can be answered, airships have no future.

    This story [cnn.com] is about a blimp currently in the skies above Washington D.C. What better way to have surveillance over a population than with a very quiet slow moving craft that can carry a large payload. Unmanned flying drones cost too much, travel too fast, don't have the long flight times, and have the payload capacity. Airships (or blimps) give more bang for the buck.

    Funny thing about that guy, Captain Scarlet;

    During the end credits, you would always see him pinned under a pile of boulders, with a lit fuse on a bundle of dynamite just out of his arm's reach [spectrum-h...arters.com],

    Or you'd see him underwater, bound by chains attached to weights pulling him to the bottom as great sharks loomed towards him [spectrum-h...arters.com],

    Or tied up with ropes while a cobra coils, preparing to strike him [spectrum-h...arters.com],
