Flew in the Bond airship which was made by a by the same people some years ago and was hooked. Want a go in this one as soon as the public are allowed on board.

They have bought the demonstrator back from the US government for a 1% of the development costs they had sunk into taking the design forward.

That they have managed to obtain a few million £ in development funding from the UK government is not really surprising. Was interesting to see that Bruce Dickinson from Iron Maiden is an investor.

Story from the BBC below:

The world's longest aircraft has just been unveiled in Britain's biggest aircraft hangar.

At first, you might mistake it for a giant airship - gas-filled balloon on top, pod slung underneath.

But the unique, aerodynamic shape of the balloon - it looks as if a series of cigars have been sewn together - means it can also generate lift just like an aeroplane wing.

That is key, because it enables the designers to make the machine heavier than air, which cuts the need to have dozens of crew hanging on to ropes holding it down every time you land.

In fact, you can land it via remote control with no-one on board at all if you like. And on water if needs be.

Let me put it into perspective for you.

This thing is two-and-a-half times longer than the distance covered by the Wright brothers' first powered flight.

With a length of 302ft (92m) the new airship is about 60ft longer than the biggest airliners, the Airbus A380 and Boeing 747-8.

It is also almost 30ft longer than the massive cargo-carrying Antonov An-225, which until now was the longest aircraft ever built.

Government funding
It costs about $100m (£60m) and the designers are planning an even bigger version that will eventually be able to carry 50 tonnes at a time.

The company developing it has now received £2.5m of government funding to develop the technology and engineering for the project.

"We are jointly funding £2bn of research and development into the next generation of quieter, more energy efficient and environmentally friendly planes," says Business Secretary Vince Cable.

"That includes backing projects like Hybrid Air Vehicles' innovative low carbon aircraft which can keep us at the cutting edge of new technology.

"Here is a British SME that has the potential to lead the world in its field."

'We'll fly over the Amazon'
All of which will be welcome news to one of the project's high-profile investors, Bruce Dickinson.

He is one of those people who can't stop achieving stuff.

As if being the lead singer of one of the world's most successful and enduring rock bands, Iron Maiden, was not enough, he is also an airline pilot, businessman, and is investing in this project.

"It's a game changer, in terms of things we can have in the air and things we can do," he says.

"The airship has always been with us, it's just been waiting for the technology to catch up."

He wants to sell them and he'll be very good at it. As we chat in the hangar, he goes through its credentials.

It is 70% greener than a cargo plane, he says. It doesn't need a runway, just two crew. And it can plonk 50 tonnes anywhere in the world you like, which is 50 times more than a helicopter.

He wants to drum up publicity with the kind of trip Richard Branson would dream up. A non-stop flight around the world - twice.

"It seizes my imagination. I want to get in this thing and fly it pole to pole," he says.

"We'll fly over the Amazon at 20ft, over some of the world's greatest cities and stream the whole thing on the internet."

Historic hangars
It is not surprising that we had to go to Britain's biggest aircraft hangar to see the world's longest aircraft.

For the best view, we had to climb the world's scariest staircase too (safe of course, but not one for the faint-hearted).

Cardington shed number one, in Bedfordshire, is nearly as impressive as the flying machine inside it.

Built 100 years ago, it dominates the skyline around here (along with its neighbour Cardington number two shed) and it is bristling with history. This is where they built the ill-fated airship, R101, back in the 1920s.

That behemoth was twice as long as the hybrid air vehicle, had a beautiful dining room and lounge on board, and was meant to herald the future of flight, right up until the moment it was devoured by fire after a crash in France in 1930.

Technology has come a long way since then. The Hybrid Air Vehicle (HAV) is full of inert helium, not explosive hydrogen.

The HAV is back in the UK after the US Army ran out of money to develop the project.

Flight plans
The US military bought it a few years ago and got this aircraft flying as a surveillance machine - it can stay in the same spot for 21 days at a time, and can fly with a lot of bullet holes in it too.

When the US defence budget was slashed, the British developers bought it back, and now they are planning the first UK flight later this year.

They are hoping to sell it to oil and mining companies to deliver heavy equipment to remote corners of the world. But they are also keen to sell its humanitarian possibilities.

The HAV, which has been named Airlander, could ferry tonnes of supplies to and from any disaster zone, day in and day out.

All you would need is a crew of two and a patch of ground, or water on which to land.

Built 100 years ago, it dominates the skyline around here (along with its neighbour Cardington number two shed) and it is bristling with history. This is where they built the ill-fated airship, R101, back in the 1920s.

That behemoth was twice as long as the hybrid air vehicle, had a beautiful dining room and lounge on board, and was meant to herald the future of flight, right up until the moment it was devoured by fire after a crash in France in 1930.

......

It should be noted that the crash of the R101 had nothing to do with the fact that it used hydrogen. It crashed in bad weather on a flight that was only carried out at all because of political pressure, flying on a certificate of airworthiness that was only issued because of political pressure, and ignoring weather forecasts because of political pressure. And it crashed because it had insufficient margin of lift to carry the load of water absorbed in the skin, which had deteriorated during the time that it was being lengthened from the original design because it could not fly. It was overweight, over budget and over deadline - but the flight (carrying a new Viceroy to India) was a political necessity for the government that built it.

The R100 (also using hydrogen), built by Vickers at the same time, was completed on budget and on time, and completed a two way north Atlantic crossing without significant incident before the R101 flew.

As a result of the R101 disaster the British dropped airships altogether, and the R100 was scrapped.

They built a runway in PNG (Tari) USD 500m i believe for 23 Antonov landings for the LNG project. So there is a market for the beast.

Komo not tari, longer than jacksons international (POM)

A further comment on the original post - far from being the longest aircraft ever built, this airship is less than half the length of the R101, and probably less than the length of many of the airships built in the first third of the twentieth century.

I think the point was that this is the longest heavier than air aircraft. The prevous longer aircraft were lighter than air.

..................................this is the longest heavier than air aircraft.

Okay......................at the risk of showing my ignorance of flight principles, how does this thing get off the ground with its 50 tonne payload ? :confused:
If it's heavier than air (plus 50 tonnes) won't it have to 'fly' to get airborne and stay up there ?

Does it take off like an aeroplane ?, can't really imagine this behemoth thundering down a runway at 100 knots or so to take off.

I initially thought the same thing, but if it's claimed power figures are accurate, it can use the props "tilted", I would assume, for vertical lift, then tilt forward for forward motion, and once enough speed was obtained the lifting force from the "wing" design would come into effect....

My guess.

According to the above article, weight is offset by being filled with buoyant helium, with the remaining lift being provided by the wing like body of the aircraft.

Won't there be a problem with a business model that uses helium? We're running out of it. Fast.

Latest figures I could find show reserves* of about fifty years at current rates of production. That hardly agrees with us running out fast. Airships are unlikely to ever represent more than a tiny proportion of use - most is used for cooling superconducting magnets, welding, and other industrial processes. The price is currently depressed by the USA selling off its helium reserves by 2015 (the reserves were set up in the 1930s when military applications of airships were considered vital. The sell-off suggests they no longer think this.)

John

*Reserves do not represent "all that there is", but simply all that is proven to be available for production at current prices. With this level of reserves, there is no incentive to develop any other sources, although it should be pointed out that almost all helium production is a byproduct of natural gas production, about 80% in a few fields in the USA, 10% in Algeria.

Interesting john, I just recall reading some articles a while back about it. Maybe they were a tad alarmist.

Still, 50 years isn't that far away with high investment new industries and demand must surely be increasing. And you can't synthesise the stuff. What's in the earth already is what we have left, unless we wait for some radioactive decay but that might take a while.

...... What's in the earth already is what we have left, ....

While this is certainly correct, it needs to be pointed out that "reserves" is not the same number as "what is in the earth already". And with fifty years reserves, nobody is going to spend any money looking for more reserves. (Actually, it is a reasonable guess that there are quite a few other producing gas fields with significant proportions of helium in their production, but whose owners are not only not going to invest in equipment to separate helium, since they will never recoup the expenditure, but are not going to draw attention of their customers to the fact that some of the gas they are buying is non-inflammable!)
