A parachute covered 32 foot, 4 frequency dome. Note the parachute stretching and how it catches the wind.
Tyvek (made by DuPont): The material of those silky non-woven strong envelope. Made from high density polyethylene fibers. Very reasonably priced from home construction stores. Look for 'Tyvek Home Wrap'. It comes in rolls 9 feet by 150 feet. It costs roughly $50 a roll. It is reasonably waterproof, dustproof, and windproof. It is white, which minimizes heating in the sun. It is reasonably easy to work with. It is pretty strong. If you want a piece bigger than 9 feet wide, you will have to build it from smaller pieces. You can get Tyvek Tape, which is made of Tyvek and has adhesive designed to stick to Tyvek.
Tyvek ThermaWrap (made by DuPont): Same as Tyvek, but metalized. Dupont even has Tyvek Metalized Tape to connect the edges of Tyvek ThermaWrap. I think this is likely the best, coolest, reasonable cost material to cover a dome. If I would have know about this, I would have bought a roll of it. It comes in rolls 9 feet by 100 feet, or 5 feet by 150 feet.
Aluminumized Mylar: Space blanket material. I saw a dome covered with this. No idea where to buy big pieces of it. Probably the ideal material to keep a dome cool. It is very fragile stuff, and rips if you look at it the wrong way. The only practical way I can think of to use this is to have it glued to rigid board insulation, like the Hexaurt construction.
Shelter systems Fabrics: Shelter systems has several woven ripstop films. There is the Translucent Greenhouse Covering, which lets in 90% of light through, their White covering which lets 60% of light through, and Clear Vinyl. The first two are $10 a yard (6 foot wide roll), and the Clear Vinyl is $20 a yard (4 foot wide roll). This stuff is very strong and water and dust proof. Heavier duty than tyvek, and a lot more expensive.
Shadecloth: Made of some synthetic material and designed to make partial shading. Won't stop wind, rain, or dust. Good for doors for privacy, or for ventilation.
Trucker Tarp: Made of 14x14 mesh of 1000 denier nylon threads. 11 mil thick. Grommets at corners and every 3 feet along edge. Reasonably priced. Very heavy duty. Waterproof, dustproof, doesn't stretch, very abrasion resistant. Lets some light through. This is the most abrasion resistant fabric listed. This is also the strongest fabric listed. For high winds, I think it is the best material, due to its superior strength. It also can be bought in large pieces so it is not necessary to put small pieces together to make a bigger piece. The color isn't great to reflect sunlight, but it works reasonably well.
Aluminet: Made by Polysack. Blocks up to 70% of UV. It is an ^1aluminized knit fabric. Not windproof, waterproof, or dustproof. Can be bought in widths up to 28 feet. You can buy it at Gothic Arch Greenhouses. It costs between $0.24 a square foot (for the 30% shade) to $0.31 a square foot (for the 70% shade). Likely will keep a dome reasonably cool, though you will need an inner cover as well to keep the dust, wind, and water out.
Silvicool Tarps: Made by Bushpro Supplies Inc.. A highly reflective tarp. Supposed to last for years. Has loops sewn into the corners and along the edges. Stock sizes up to 18 by 24 feet. Can be made in custom sizes. Looks to be dustproof, waterproof, and windproof. If I was building another cover, I would call these folks up and find out more about this.
Reflectix50: Highly reflective 7 layer thick insulation, 5/16 inches thick. Aluminum color on both sides, bubble wrap in the center. You can buy it at Atlanta Supply Co.. A 50 foot by 4 foot roll costs $61. Likely waterproof, dustproof, and windproof. Not as strong as fabric or tarp

Monolithic designs, manufactures and markets a prime ingredient used in the construction of Monolithic Domes, Crenospheres and EcoShells: the Airform. It’s an inflatable structure, made of PVC-coated nylon or polyester fabric, that determines the shape and size of a dome.
Our other specialty fabric structures include compost covers, grain covers, condensate ceilings, methane tank liners, water tank diaphragms and tension tarps.

I had to construct hemisphere in MATLAB ,so I did this:
The code was not written by me so I want to understand this,when I replace ' in
phi = (pi/2)*(0:2:n)'/n;I get following error : operator *: nonconformant arguments (op1 is 1x16, op2 is 1x32)
Please explain why is it essential....
Also,I wanted to write an easier code for sketching hemisphere.any idea for some shorter command/method I can use in matlab.... |
