btw, OP, have you taken 8th grade physics yet by any chance?
[QUOTE=Sir Tristan;25072084]btw, OP, have you taken 8th grade physics yet by any chance?[/QUOTE] Don't worry, the OP knows what he's doing. I mean seriously, people don't study for years to become educated in this stuff anyway, right?
[QUOTE=Ragy;25072123]Don't worry, the OP knows what he's doing. I mean seriously, people don't study for years to become educated in this stuff anyway, right?[/QUOTE] bah i guess you're right fuck education when you can just use your imagination
[QUOTE=Sir Tristan;25072144]bah i guess you're right fuck education when you can just use your imagination[/QUOTE] I'm sure he will have no problem with this. I mean look, he built a time machine to buy Microsoft stocks before they went big.
yeah, you're right i mean, what is implausible about this [img]http://www.visualparadox.com/images/no-linking-allowed-main/airship800.jpg[/img] i don't see anything physically impossibly in that picture! [editline]08:09PM[/editline] (OP's 3 balloon design)
[QUOTE=Sir Tristan;25072067]i don't i what this is literally probably the dumbest thing i have ever heard someone ban the OP seriously[/QUOTE] what makes it so dumb
[QUOTE=Greg73;25072006]I've got the measurements around here somewhere...The wood type is prolly gonna be pine, I have the amount of helium in my notebook which I can't find, but that's for an approximate amount, lifting about [B]2,500lbs[/B], using the material used for sails sounds like it might work, I'd have to put some research into it, and my lifting method is quite simple. Have two helium balloons and one balloon that's "empty", (_helium_empty_helium_) basically you have a heating system attached to the air/empty balloon, and when you pump hot air into the middle balloon it heats the other two, causing the helium to expand and move faster, thus increasing the lift capacity. For lowering the ship, simply use the same method for hot air balloons: have a hatch in the top which can be pulled open to release hot air.[/QUOTE] Wait what? You're nearly lifting a car there dude. I thought you just wanted to make a 4' x 4' box with balloons on it or something but now this is just ridiculous.
[QUOTE=M2k3;25072305]Wait what? You're nearly lifting a car there dude.[/QUOTE] Don't worry. OP can bend the laws of nature.
[QUOTE=M2k3;25072305]Wait what? You're nearly lifting a car there dude.[/QUOTE] That's not the total amount, that's just an estimate for lifting around 2,500lbs.
it would [I]never work[/I], the amount of helium required is absurd, the physics behind this are impossible, just as well, the amount of money that it would cost to create this is so vast that he could never attain it, even with his alleged stock in microsoft congrats OP, you have 2 shares of microsoft i.e. you have 48 dollars
This reminds me of that classified ad asking for assistance during time travel. [img]http://www.myconfinedspace.com/wp-content/uploads/2007/01/time-travel-want-advert.jpg[/img]
Im mastering in Mechanical engineering and making something fly with helium is not that hard. (Weather baloons annyone?) All you really need is a bag of helium. Bags cannot be steered or directed tough for that you need a blimp, which is nothing more then a rigid bag of helium with propulsion. The main problem in this would be getting a light and stiff frame to contain the helium balloon and is also strong enough to hold stuff like engines n shit without weighing more then the helium can lift. This frame is usually made out of alluminium and is called a space frame. You can buy the engines, batteries (I would make its propulsion electric) batteries, seat and whatever, the hardest part would be making and calculating the spaceframe. Both Solid edge and autodesk inventor have freame generators that can speed up the process of constructing a frame but the calculations would probably by finite elements calculations (which are damned hard)
The canvas material would be extremely costly. Helium leaks through just about everything, especially when pressurized like that.
[QUOTE=ThePuska;25072564]The canvas material would be extremely costly. Helium leaks through just about everything, especially when pressurized like that.[/QUOTE] Exactly. I heard that Rip-Stop Nylon would work, but after looking into it I realized they were exaggerating a bit.

Tell me more about this design.
[QUOTE=Sir Tristan;25070911]i.e. you're a dumbass you don't have 50,000 dollars to freely spend in fact, you're 12[/QUOTE] 50,000 dollars is luxury sedan money. 5 million dollars is airship money. A 15 cubic foot cylinder of helium costs $40 dollars, to give you some idea of how ridiculous the price would be, not even considering the price of the frame, fabric, and the propulsion system.
[media]http://www.youtube.com/watch?v=2GLrr_Xp0qc[/media] You should look at people who have done things like this guy, or Larry Walters, the famous lawn chair balloon guy. Also, cluster ballooning in general. About 170 huge balloons to fly one man in a chair. The amount required for a whole machine with an engine, plus you, would be a lot. [editline]08:32PM[/editline] Larry Walters story: [media]http://www.youtube.com/watch?v=iTF1b0k3dZQ[/media] What a fucking baller. Reports say he used 42 weather balloons.
I swear, next time I'm takin this to 4chan. I'm sure there's much less butthurt there.

Determine the volume of the balloon. The volume of a sphere is 4/3 * pi * r3, where r is the radius of the balloon. So first determine the radius of the sphere (the radius is half the diameter). Cube the radius (multiply it by itself twice: r*r*r), multiply by 4/3 and then multiply by Pi. If you are measuring your balloon in feet, that gives you the volume of the balloon in cubic feet. One cubic foot of helium will lift about 28.2 grams, so multiply the volume of the balloon by 28.2. Divide by 448 -- the number of grams in a pound -- to determine the number of pounds it can lift.

[QUOTE=Greg73;25071517] Just sayin, impossible is what they said to Bill Gates. Come to think of it, I think the Wright Brothers heard their fair share of the word.[/QUOTE] Haha, comparing yourself to the wright brothers, pretty full of yourself aren't you? The difference is the wright brothers were making something useful, you're making something that is completely redundant, pointlessly expensive, and will probably be blown away by wind.

I've always wanted a flying office. Some sort of comfortable, wood-paneled office complete with desk, library, and writing station--only strapped to the bottom of a blimp.

Use like inflatable bed pumps instead of heating the air. Heating the air sounds a lot less efficient
you'd be better off tieing 20,000 helium balloons to your house better yet, fill a rubber dingie with helium, thenb tie hundreds of balloons to that, that's the best airship you can get without $100,000 and 4 years of education [editline]11:46AM[/editline] [QUOTE=FunnyBunny;25073373]OK GUYS I'm gonna make a space frigate!

Since everyone else isn't going to even attempt to help the OP. OP, For the cabin you'll want to go as light and as cheap as possible. Make it as cramped as possible, you don't plan on living in it, you don't need the space. For the helium bags you can't use plastic or traditional balloon materials. You are going to have do research on these materials. The next thing you may want to do is look at making internal skeletons for the helium bags. I'm not going to lie, this will be expensive, don't go cheap. If you actually do this bring a fucking parachute. Do research on architecture and materials.
OP might want to look at this. Cheap viable alternative. [url]http://www.popularmechanics.com/technology/aviation/airships/4278917[/url]
