Bats Inspiring Future Micro Unmanned Aircraft

Posted by kdawson on from the same-bat-station dept.

coondoggie writes "It's not the first time researchers have tried to emulate flapping as a way to fly aircraft, but US Air Force-funded researchers are now looking at how bats move to help them develop future micro-aircraft. According to these researchers, birds, bats, and insects have some highly varied mechanical properties that researchers have so far not utilized in engineering flight vehicles. The idea is to reproduce bat mechanics and develop technology could lead to small, remote controlled aircraft able to move in places where fixed-wing aircraft have a hard time — like the interiors of buildings, caves, or tunnels."

      Actually, the "Bat Bomb" was a striking success.

      The "bomb" was essentially a large casing, filled with a stack of "honeycombs". Inside each cell of the honeycomb was a Mexican Freetailed Bat carrying an incendiary device.

      The bats were chilled to induce torpor, then fitted with the device. While still chilled, they were loaded into the honeycombs and the devices were armed by pulling the string through the top of each cell. The combs were then strung together and loaded into a casing.

      The casing would be dropped over a city, and once it reached 4000 feet, a chute would deploy and the case would fall off. The honeycombs would then fall like an accordion, stretching out. Each bat would then be shaken out of their cells and onto the top of the bottom cell. The device is now armed.

      This was actually deliberate, as it gave the bats time to warm up, get their bearings and fly off for shelter.

      The intent was that the bats would fly toward homes and buildings, seeking shelter from the daylight. After 20 minutes, the incendiary device would ignite. And since most Japanese homes of the time were made from washi paper, wood and bamboo, the resulting fires would be catastrophic.

      The concept worked perfectly, as the Army found out quite by accident. Here's a video. Advance to 6:25 for the "successful test"

      Unfortunately for a few million Japanese, but fortunately for the bats, the program was canceled in lieu of the A-Bomb.

      Engineers have always looked to nature for design inspiration.

It has also had some notable successes, most recently with those "sharkskin" swimsuits.

      But the thing that is certain is that every time the routine use of natural inspiration is pointed out to anyone who is completely ignorant of all good engineering practise for the past few centuries, they will boldly announce that it is "new" and "surprising" that engineers would do any such a thing. Unfortunately this leads to journalism that misses everything interesting.

      I'm afraid I'm going to have to disagree. I think that we don't do enough biomimetic design, especially for production systems. Look around you. What was built using biological principles? The answer's probably "not much".

      The problem seems to be engineers' blindness to "solved problems". Once somebody comes up with a workable solution, everybody just iterates upon it rather than stopping and rethinking the problem entirely. Take the "bat-craft" example. UAV design has consistently been a process of taking classic aircraft design, and then shrinking it. The problems are well understood, but you're never going to get any revolutionary features.

      A couple of years ago, I was part of a competition for AUV design (autonomous submarines). Every single entry, except for ours, used the same principles that we've been using on submarines for forever. Pressure hull, with tandem thrusters for turning and propulsion. We tried to go with a more "natural" design, copying fish (flooded hull, the whole body was a control surface).

      Talking to the big defense contractors that build these things for the military, all of their designs lacked any biomimetic features. Current AUV design consists of taking classic submarine designs, making them smaller, and whacking out the crew compartment. A lot of them are pretty cool, but they're certainly not borrowing anything from nature.

      The same situation exists with UAV design. Look at the designs for the Int'l Aerial Robotics Competition. These are the engineering students that get recruited to design and build "the real thing" for Northrup Grumman and General Atomics. Smart guys, but they're (generally) not looking to nature.

Make them autonomous and the fun really starts (what happens whey they accidentally get into wake turbulence from a nearby jet?).

      Tiny UAVs are even more of a hazard - think bird strikes, except instead of a somewhat feathery lump of meat, you have metal, composites, electronics and fuel. I'm sure the folks at LAX would just love to have a jet suck one of those into their engines on takeoff or landing. Something the size of a Predator would at least have a chance of being seen by the pilot and hopefully avoided, but those tiny ones...

    The idea is to reproduce bat mechanics and develop technology could lead to small, remote controlled aircraft able to move in places where fixed-wing aircraft have a hard time â" like the interiors of buildings, caves, or tunnels.


    Why would you want to take the time and effort to research a bat based ornithopter RPV just to move around in buildings? just use a rotary wing aircraft instead. I have a $20 helo that works just find in my living room. I could easily get a larger one for $50 that could carry the extra weight of a wireless 2.4GHz mini-pinhole camera.

      -----No, I'm assuming that it would be used at all. Whether or not it is being used as a weapons system or surveillance/recon system, it can *still* be brought down by wayyy cheaper methods, from a shotgun to an electromagnetic pulse, that can easily be either requisitioned or built.

They're doing something right.

    Referencing the post above who suggested that artificial bats could easily be disposed of by a shotgun, have you ever tried to aim at a bat? They are difficult enough to follow with low power binoculars. They also obviously have a fair bit of computing power in rather small brains.
