The Aluminum Airship of the Future Has Finally Flown - Aeroscraft (1 Viewer)

[Christo]

There was once a time when man looked to the skies and expected to see giant balloons rather than airplanes drifting above. The Hindenburg Disaster promptly put an end to those dreams. But nearly a century later, one company may have finally figured out how to build a dirigible suitable for the 21st century. Just don't call it a blimp.

This fully rigid airship, dubbed the Aeroscraft, differs fundamentally from, say, the Goodyear blimp. Blimps, by definition, have no internal structure and maintain their shapes only through the pressure of the gas they contain; when the gas escapes, they deflate like the gigantic balloons they are. Rigid airships, like zeppelins before them, maintain their shape regardless of gas pressure thanks to an internal skeleton structure—the Hindenburg utilized highly flammable balsa wood, but the Aeroscraft's is made of aluminum and carbon fiber—and maintains its buoyancy with a series of gas-filled bladders. And unlike hybrid airships, the Aeroscraft doesn't require forward momentum to generate lift via a set of wings. It's all helium power.

The Aeroscraft has been under development by Aeros Corp, the world's largest airship and blimp maker, since 1996. The project has received over $35 million in R&D funds and the government has even lent the company a couple of NASA boffins to help develop the aerodynamics and control systems. And with the successful launch of its half-scale prototype, the Pelican, last weekend, the investment looks to have paid off. The future of lighter-than-air travel looks to be imminently upon us.

At 266 feet long and 97 feet wide, the Pelican prototype is just about half the size of what a full-scale Aeroscraft will be. If completed the Aeroscraft will measure more than 400 feet long and be capable of lifting 66 tons or more.

Unlike blimps that maintain a constant buoyancy and rely on ballast and fans to adjust their altitude, the Aeroscraft will employ a unique bladder system that can alter the craft's static heaviness (relative to air) at will, dubbed COSH (Control of Static Heaviness). The system actually works quite similarly to how submarines use compressed air to float.

The Aeroscraft is equipped with a series of pressurized helium tanks. When the pilot wants to increase altitude, non-flammable helium is released from the tanks through a series of pipes and control valves, into internal gas-bladders called helium pressure envelopes (HPEs). This increases the amount of lift the helium generates, reduces the craft's static heaviness, and allows it to rise. When the pilot wants to descend, the process is reversed. This allows the Aeroscraft to easily land and take on cargo or passengers without having to be tied down or add external ballast. Additionally, the Aeroscraft will be equipped with a trio of engines—one on each side and a third on the belly—and six turbofan engines to provide thrust and augment the COSH's lift, as well as aerodynamic tail-fin rudders and stumpy wing control surfaces, for high speed travel—that is, above 20 mph. Oh it'll get you there, it's just going to take a while.

Now, the US government didn't drop $35 million just to build a better balloon. Airship technology is being developed to provide a vital role in modern world: runway-less cargo delivery. Getting even modest amounts of supplies and people to remote areas by plane can be a nightmare; you've either got to find a suitable runway or be prepared to parachute. From the Australian outback to the Alaskan hinterlands, there are plenty of locations around the world that are simply inaccessible to conventional airplanes. Not so with the Aeroscraft.

With a proposed lifting capability of 66 tons and no need for a landing strip, these airships should be able to deliver just about anything just about anywhere in the world. Cargo can either be loaded into the Aeroscraft's internal cargo bay or slung under the blimp using the company's proprietary ceiling suspension cargo deployment (CSCD) system. which automatically balances the hanging load to prevent it from swinging around and crashing the dirigible.

While the Pelican successfully lifted off last Sunday, it did so under cautionary tethers. Its first untethered flight is expected to happen within the next few weeks. Eventually, the company hopes to produce a trio of Aeroscraft models: the 66-ton capacity ML866, the 250-ton ML868, and the 500-ton ML86X. There's even discussion of turning them into giant floating hotels for serene 80-day global circumnavigations.

[grateful zed]

that much aluminum sounds bad for the environment.

If someone could ever solve the problem of the "Airship" that could equal or even come close to speeds necessary to making them both safe from attack and economical in the sense of logistically delivering goods when needed (military supplies, humanitarian aid, consumer goods), they'd have the holy grail of air transportation.

A C-5 Super Hercules cruises at about 500 MPH and carb carry 135 tons of cargo. It does burn a ton of fuel. This prototype can carry 66 tons and the speed isn't listed, but if bet my life it can't hit 500 MPH. Probably lucky to hit 150-200. Cool, but not realistic unless you want a floating hotel.

Very cool

 

[Quez]

I could see Amazon getting down on this for deliveries.

Putting distribution centers closer to the customers.

Oh, would having facilities only in a state's air space still require state sales taxes to be collected?

When do we start posting Archer quotes? One of the best episodes of the series imo.

Hey Christo, are you sad you never got to have sex with the Hindenburg?

We currently deliver cargo by truck at an average of 50 mph.

If this thing is cost effective then the speed isn't an issue.

How much runway do you need to land a C-5? I can see these being situated in various regions for emergency measures. Fill them up and land them in typhoon/hurricane/tsunami affected areas.

 

[Sand]

We already have a big problem with helium supplies. This is a no go just from that perspective.

Interesting idea. Just not practical.

 

[Joe Summer]

This will go over like an aluminum balloon.

 

[Officer Pete Malloy]

Didn't the old zeppelins go like 70-80 MPH?

At max takeoff weight you need a runway 8400 ft long. Max landing weight requires a runway of about 5000 ft. Could use less maybe but pilots are not trained to land on anything shorter.

Hindenburg had a max speed of 84 mph. Cruising speed was 76 mph.

That's the advantage of this thing, no? The equivalent of a giant helicopter in terms of where it can go- without having to rely on runways.

Just as long as Christo doesn't want to have sex with it.

Whatever happened to that thing?

 

[kentric]

Hindenburg had a max speed of 84 mph. Cruising speed was 76 mph.

But what was the relative speed of the zeppelins versus prop planes at the time. I'd say that with the technological advances these things can go 200-225 mph, you should consider this as having near the same relative speed to a jet as the zeps had to the prop planes. And yes, I'm pulling most of this stuff out of my ###, but you hopefully get the general point I'm trying to make.

According to the website the full size version will be 555 feet long, payload of 66 tons, a top speed of 120 knots, a 3100 mile range and an operational ceiling of 12,000 ft.
