China's DIY Aviators Take Flight 113
ScuttleMonkey writes "China’s emerging aviator class is spreading its wings with a plethora of approaches, from the ramshackle to the sophisticated to the potentially revolutionary.

There are several flying examples in the U.S. of amateur-built helicopters. Granted, most of them are built from professionally manufactured kits (i.e., the manufacturer builds a prefab kit, and the "builder" assembles the parts), some of which are relatively sophisticated. Google Rotorway and Mini-500 (I think the Mini-500 is defunct now, but there were several built back in the '90s).
...but *anybody* can dream, especially if he doesn't realize how incompetent he really is.
I would argue that often times, those who don't realize how incompetent they really are are, in fact, the ones who make the biggest advancements. They don't know it's impossible before they try, therefore they are the ones who go ahead and do it anyway. "The Ark was built by amateurs; the Titanic was built by professionals." ;)
The next step up is the human powered guy. He needs a long carbon fiber boom as the main longitudinal structural component, and probably another one to carry the lift generated along the wings to the main boom. That's pretty expensive. Once he has that, then the drivetrain is bicycle technology.
Human powered flight is about as difficult as aviation gets, at least for right now. The problem is that it takes more energy than most people realize to lift a human body; we simply don't have the strength or endurance to generate that much power for very long. I believe the current record is 199km [gizmag.com] -- not too shabby, and much better than I thought before I looked it up just now. FWIW, building the carbon fiber boom isn't difficult (although the carbon fiber is relatively expensive -- but less so than most power plants for experimental aviation). I did the calculations for a carbon fiber wing spar about a decade ago, and estimated a ~1500 pound airplane stressed for a max G-loading of +6/-4 (plus reserve) would cost around $1000 - $2000. It isn't cheap, but it's certainly within the realm of possibility for someone of reasonable means. There was also a guy in Arizona about ten years ago who built a foot-launched sailplane called the Carbon Dragon, that would probably be worth studying if you were interested in trying to build a DIY human powered airplane. He sold plans for the airplane, but I believe he died a few years ago, so they might be a little hard to find now.

That's not a bad way to do it. I remember reading magazines dating from the late '60s (I read them in the '90s, though) about people who had build entire airplanes with this method. My experimental airplane [google.com] uses a slightly different method, that also might work. The wing spar is an aluminum tube with foam ribs glued to it. The leading edge is 2024T3 aluminum wrapped over the ribs to make a stiff skin over the first 1/4 of the wing, then the entire wing is covered a material made by 3M for building greenhouses called Tedlar (as the story goes, 3M freaked and pulled Tedlar from the market after hearing people were building airplanes out of it; I haven't verified the story). It looks like a full-scale model airplane wing covered in clear Monokote ;) For human powered flight, I would probably replace the aluminum spar with carbon fiber, like you mentioned earlier, but the principle is the same.

A huge trend in the near future (0-20 years) will be home and distributed engineering (inventing) and manufacturing. People will trade information on technologies, how-to information, plans, and parts to make sophisticated products in their home or workshop.
This is not to say we're all going to get replicators or nanotech manufacturing like in "The Diamond Age" but the level of sophistication of home built products is going to go way, way up. From small appliances to tools to vehicles to weapons, it'll be possible to make a large number of items in places other than traditional factories, in small quantity and high quality.
To see this sort of thing emerging, look at efforts like Reprap to make a self replicating 3d prototyping machine (which probably won't be 100% self replicating for a long time, but which is a great starting point for at-home applications of the technology) or home CNC machines like router tables and small CNC machine tools. You can buy a CNC milling machine capable of producing small parts eg. for firearms and small engines for less than $3000 with computer. Once these become widespread part libraries for them will be as available as clip-art. Want a new part for your bicycle? Download the pattern, place the raw material in the machine, and walk away.
As quality items become harder to find in mass produced outlets, items made at home will take their place. Any item with a niche market will probably be made in these mini manufactoria... there won't be a profit any more in making small quantity items since there'll be tremendous competition from small manufacturers.
No need to keep an inventory of obscure auto parts on hand (or to pay for storage space or sunk costs in the inventory). Just keep the pattern available and churn out parts as needed. Need a part you don't have a pattern for? Ask someone on the internet to measure their part and make a pattern from it, using the same CNC mill to automate the measurements.
I like the trend myself... but can you imagine the fit the government will throw when it figures out it can no longer regulate eg. firearms because anyone with a CNC mill can turn one out in a day or two? I can see them at first trying to ban home manufacturing, trying to ban precursor items and materials, then trying to create an overarching government agency to police the whole thing.
It'll be similar to recording companies figuring out they're no longer needed since anyone can distribute or purchase music on-line without their involvement.
Likewise I can see large corporate manufacturers of some items begging for a government bail-out because no one wants to buy their mass produced crap any more. Why pay $100 for a cheap wal-mart bike when the CNC machine shop in the next town can produce one with 3x the quality for the same price? Why pay a computer store $35 for a plastic keyboard when you can get a solid brass one with better components made at home?
