World's Largest Aircraft Seeks Investors To Begin Operation 140

An anonymous reader writes: The Airlander 10 is significantly larger than a 747. It's an airship that incorporates elements of blimps, planes, and hovercraft. Buoyed by a vast volume of helium, it's capable of cruising at a speed of 80 knots. It was built as a military venture, intended to be used for surveillance tasks. But as the war in Afghanistan wound down, government officials found they had no use for the airship. They ended up selling it back to the company who made it for $300,000 — after paying them $90 million to build it. Now, a small group of investors are trying to get it operational, in part to show people how safe the technology can be, and to hopefully spur construction of more airships.

      The Hindenburg and other airships were filled with volatile hydrogen, modern airships use inert helium. The problem is, helium is quite expensive in that volume. The fear at hydrogen airships was well founded, the Hindenburg wasn't even the worst airship disaster, that only killed 36, the worst disaster was the R101 which killed 48. Airships were not only vulnerable to explosion, they were unstable in high winds and storms. After the Hindenburg airships by and large stopped using hydrogen but there were still a lot of crashes due to weather.

      The design in the article uses helium which isn't unstable like hydrogen but the problem of weather still remains. But that isn't what will kill it, it's economics as helium is going to be expensive in the quantities they need and who is going to pay for an airship to freight something at 80 knots when if it isn't time critical, a bulk carrier will do it for less.

        I think this statement is taking things very far out of context: in the context of modern or even vaguely recent air travel, that was not a good thing. In the context of 1936, it was barely a blip. Air travel in 1936 was primitive and dangerous: the classic planes like the DC3 were just introduced contemporarily with the Hindenburg. What was common at the time was things like th Ford Trimotor. Long range planes had many engines partly because the engines simply lacked the reliability due to pushing the technology so far: it was routine to lose one engine in a long flight and mechanical problems frequently caused planes to land early. It wasn't long since planes were designed to allow in-flight engine maintainance.

        Additionally, crack porpagation and metal fatigue were very poorly understood and as planes transitioned from wood and linen to aluminium in the 30s, this was the cause of some parts flat-out falling off in flight (things like wings).

        The main problem with the hindenburg was that it was large and grand and a film crew witnessed it's demise.

    Most people seem to focus on the safety of airships, in the light of the Hindenburg, R101, etc. Surely a more significant problem is the wind? Any amount of wind is going to make landing and takeoff hazardous, and making much headway against a strong headwind is going to take a lot of power with that much windage. Good luck to them, maybe there are enough fair-weather opportunities to make it pay, but this aspect is seemingly never discussed.

These were the promises (or dreams) being made a few years ago.

And suddenly everyone appears to be silent about those prospects... nothing to fire up the imagination of a dreamy eyed 12 year old except for the fact that the Airlander's "unusual shape emulates a wing, giving it lift as it is propelled forward by its four engines, as well as from the 38,000m3 of helium that fills its hull."

      If the potential investor isn't interested in the technical gobbledegook, he probably shouldn't be investing. Or at least he shouldn't be at this point, when the technology is still unproven and the hardware still in the prototype stage.

      On top of the irony that on a site for "news for nerds" a comm

  • The PDF on their site says that this will be able to lift up to 10.000kg. This doenst seem too impressive, considering that your run-of-the-mill CH-47 Chinook helicopter can lift up to 12.000kg.

    Why would it come out on April 1, and why would you compare it to a 747-400, not even the largest 747?
    The An-225 is 84m long.

  • Why is the speed measured in knots? Do they throw ropes off the side of airplanes to measure how fast they're flying? I'm not in that business so I genuinely don't know. I just figured km/h, or mph if absolutely necessary, would paint a clearer picture. I mean if I ask Google what 80 knots is, he says its 148.16km/h. I can work with that number. I can relate to that number. But who measures things in knots? And why?

      A knot is a nautical mile per hour. A nautical mile is... "approximately one minute of arc measured along any meridian"*. IOW, it's used in the marine and aviation worlds (including weather) because it makes notepad speed and navigation calculations easier.

We still have the strategic helium reserve, pay companies to make, (not make, it can't be made) to collect helium, store it in some abandoned mines, and get that supply of helium may be for free for the defense department, fill it up in a balloon, abandon the project, sell it to private companies at some ridiculous throw away prices.
