New Type of Hot Air Blimp

An anonymous reader writes to let un know about a story up on the Experimental Aircraft Association site about a new kind of blimp. From the article: "Alberto, whose name pays homage to Brazilian aviation pioneer, Alberto Santos-Dumont, is 102 feet long with a 70-foot diameter and uses hot air rather than helium for lift. Its innovative foldable frame (much like an giant umbrella) creates structural support of its hot-air envelope, and it has a fly-by-wire vectored thrust steering system. Alberto is a hybrid; a hot-air balloon with aluminum ribs that looks more like a blimp, but with a tail propeller that gives it directional control." The home site of the blimp's developers has a timeline, photos, and a video of the blimp in flight.

Cool!

Another piece in the puzzle

This blimp isn't just a step forward for aviation, it's a major step forward in the development and construction of a viable space elevator. One of the primary problems that has plagued the space elevator proponents is the identification of a cost effective means of transporting the carbon nanotube teather from the Earth's surface to a proper orbit. This blimp and advances in carbon nanotubes could signal the beginning of cheap space transport for all mankind.

Mark this day on your calendar folks.

Re:

How can a blimp with a propeller ever leave the atmosphere?

Re:

i thought that it worked the other way around, dropping the tether from the top. (don't know a lot about space elevators)

Re:

Well, we had to get up to the top to drop that carbon nanotube teather... so this blimp can do it.

Re:

But as another post has already pointed out this blimp wont get you out of the atmosphere. So where is the top of the space elevator going to be? I don't think this thing will get you very high at all. Weather balloons will only get you to 40km or so (acc

Re:

Aggghhhhh... that's the sound of my space elevator dream crashing to the ground in a massive carbon nanotube wreck.

Re:

Just to add to that, the center of a space elevator would be at over 40000km (Geosynchronous orbit). So even 40km is a few orders of magnitude off.

Re:

Blimps can carry huge loads if you make them large enough. A large unmanned blimp could be used as a high-efficiency first stage -- just fire the Saturn rocket up through it after the blimp reaches max altitude, saving that first few vertical miles worth

Re:

Carbon nanotubes combined with a nanobot skin could protect mere mortals from the radiation.

Re:

No, we agreed that you encase the personnel car with water to shield from the radiation. And you fill the water with sharks with laser beams as an extra defense mechanism. That was the consensus that was reached.

Re:

And you fill the water with sharks with laser beams as an extra defense mechanism.

But won't all that radiation cause the sharks to mutate, so then we'll end up with the entire crew of the elevator devoured by mutant air breathing lase

I've seen more practical aircraft

The fact is the booger is huge, there is no excusing this fact. Add this to the whole who the hell has that much space to store a blimp factor and the next who the hell will police the skies (as tickets get much harder to hand over when being able to pull over becomes a non option. The entire article is filled with it issues (namely size and practicality) that would make a helicopter although more expensive millions of times more practical. This is something like why drive your car to work when you can use this perfectly awesome toy wagon with new wheel design.

Re:

First off, before you dismiss blimps you should be informed that in the 4th century the Koreans used blimps to successfully invade and conquer Japan. The technology may be old but it's very effective.

Yeah, but would I get an IR-Ticket for my giant penis shaped balloon?

I hope not... but if you did it could be an article on Your Rights Online. Everyone should have the freedom to own a big penis shaped blimp.

Are you kidding? It's only 100 feet long. The Hindenburg was over 800. You, and everyone else complaining about 'practicality' have missed the point of these craft in the modern age: they're cruise ships in the sky. They are leisurely travel for people on leisure time. Just like people take cruise ships on vacation instead of jets to get from one island to another, except these things are cruise ships that can go from London to New York to Las Vegas. Hopefully the 100 foot toy size is a proof of concept. You need an 800 foot job to economically carry enough passengers and have nice enough accomodations.

Re:

You do, if you have a two-car garage and one car. It's collapsible, and the lifting gas is expendable (as opposed to helium which is very expensive: helium ballons have to be kept full or emptied with exp

FYI, there was a recent episode of Nova [pbs.org] on PBS all about Alberto Santos-Dumont.

Interesting source of lift

Seeing how helium is actually quite expensive (paid $70 for 300 cu ft. at a local welding supply if memory serves) it's interesting that this contraption uses hot air. I wonder what the economics of hot air look like; i.e. cost of fuel to maintain lift, etc.

Re:

The first thing I thought was to use hot HELIUM. I mean, why not? Surely hot Helium will have even more lifting power than regular helium.

Re:

Not bloody much. The lifting power of a balloon/blimp depends on the difference in density between the gas inside and the air outside. At standard sea-level temperature and pressure:

If they use black fabric they may not require fuel

There are solar heated hot air balloons...

Zeppelins are better

I always zeppelins to make a come-back. It looks like they are currently used only for sightseeing and surveying, though.

I don't suppose this new hot-air balloon can compete. It really does look like a cross between a blimp and balloon, though.

This would make the perfect album cover! Someone resurrect John Bonham and get the band back together.

Cheap Fuel

This will be the ultimate way to get around Washington DC. Plenty of free fuel....

Commuter blimps...

Whatever happened to commuter blimps? IIRC, There was a proposal 20 years ago to have commuter blimps travel between San Jose and San Francisco (50 miles) that would take an hour each way. I guess the air went out of the proposal since it wasn't any faster

Not a Blimp

Airship nomenclature defined these:

Type A - Rigid
Type B - Limp (hence the nickname "blimp")

This has a rigid frame inside so it cannot be a blimp.

You're wrong. Blimp was probably named for the noise it makes when you strike it. Take a look here [wiktionary.org]

Their patent is for hot-air ballons with internal frames which is much more new and innovative than 90% of patents out there (I'm looking at the company who's suing Nintendo for the trigger on the wii)

Stop being a hater for a single second and think about this, this thing is completely new. It's simple to fly, easier than hot-air balloons or blimps. Just think of the uses, replace a couple tour buses with this thing and you get the same maneuverability, better views, and little to no traffic on your tour. What other vehicle can do that?

Re:well

...but it seems better than being in a balloon with no real control ...

A term of some use here is "dirigible", i.e. "something that can be directed". Term for lighter-than-air airships of the past was dirigible balloon, shortened to "dirigible" in common use.

As a young lad I read Doc Smith's stories (before learning that) and had this terrible image of his dirigible torpedoes being these explosive little balloons running around in outer space...

Oh, and the term "blimp", like "jeep", was a military term shortened in general use -- originally it was a "Type B-Limp Balloon"
