HAV skycat hybrid airship cardington

Hi there

amazing piece of news from Cardington and an airship manufacturing company based there,

Hybrid Air Vehicles, they have in the last few weeks won a major contract in the US working with US company Northrop Grumman ,

the contract is to build 3 huge Hybrid airships just larger than the length of a football field, for security and reconnaissance deployment in 11 months in Afghanistan, will be amazing to see these huge aircraft fly. the contract is for $517 million (£350.6 million)

Brilliant concept - and such versatility as shown in the BBC News Item above.

I suspect this must be worrying the traditional Aircraft and Helicopter industries and their lobbyists.

As with most engineered solutions there are still some compromises required with HAV's. There may be ballast management issues which may make them slightly less flexible to use than say a helicopter in some situations, and their load carrying capability drops with altitude which can make them difficult to use in say a war zone where they can come under ground fire.

But for a lot of uses, especially commercial cargo transport or long duration aerial surveillance, they are a cracking idea.

the HAV304 is an amazing design, it takes of heavy, full of fuel, forward movement makes it fly like a big wing, the ship will fly to were it will patrol, 20,000 feet up, as it patrols it burns the fuel making it lighter and lighter, at end of mission the lighter ship is powered down with its engine power, it is a clever way round an historical airship problem, and one that doesn't involve venting gas,

with the big American rigid airships and i think they tried and a couple of British ones too to recapture water ballast from the exhaust systems from the engines, the Americans got this to work nearly 80 odd years. the R101 had a series of gully's on the top which channeled water from rain and clouds it flew through, it seemed to work very well.

first flight is due to happen this summer in the US, unfortunately it wont fly at cardington, and HAV have moved from Cardington now and are currently officially based at Cranfield.

there website is full of interesting info on the skycat range, and i hear on the grape vine that they want to come back to shed 1 when restored to continue the skycat program and get a commercial hybrid air vehicle in the air, flying from Cardington the official home of British LTA.

their website is http://www.hybridairvehicles.com
