This might not have been a blimp. It was rigid. It was all silver grey and you could see a rigid structure over the entire surface in what looked like panels very big long panels. It was huge you could only make out the first part of this thing through … Read more ». When I was a kid in Georgia, Blimps would come over most every year, in groups, I think they were Navy. They still come over to advertise casinos or headed to a sporting event. None fly very high.

The Squadron was ZP 2. There were six K series blimps assigned to ZP 2 which was decommissioned in the mid 50s. I believe the concept is amazing. Thanks, Noah, you are correct: the U. Navy airhips Akron and Macon were intended as flying aircraft carriers:. In in the American Southwest there were people who reported military men operating dirigibles. Some of them, speaking to the locals said they were preparing to use them in Cuba. This was a few years before the Spanish American war.

One dirigible was shot down over Aurora Texas by … Read more ». There are three hangars at Lakehurst capable of housing the large blimps, and two of them have housed blimps within at least the last 5years. Development of airships, for cargo transport purposes in infrastructure lacking regions, is aldo underway here in Brasil. What is an Airship? What is a Dirigible? What is a Blimp? A blimp has no rigid internal structure: If a blimp deflates, it loses its shape.

What has changed, Hunt said, is the technology available to build and operate airships. When the Hindenburg flew, operators had only the most basic means of predicting weather patterns and the crudest materials for fabricating airships. But for all their high-tech advances, Hunt said, the new airships would still get their buoyancy from hydrogen, a highly flammable gas that is 14 times lighter than air.

The possibility of another giant explosion has some pushing back against an airship renaissance. Hydrogen, on the other hand, can be extracted from water and so would much cheaper. And since hydrogen is lighter even than helium and thus more buoyant, it would mean airships could haul more cargo. To minimize the risks associated with hydrogen, Hunt envisions getting rid of the crew.

The airships would operate autonomously — and would be loaded and unloaded by robots. As an additional bonus, Hunt said, the fuel cell would generate as a byproduct water that could be released as the craft passed over regions hit by drought. Lanteigne, who has written extensively about airships, said building such colossal craft would be an enormous challenge. The cone shape of the blimp also helps to generate lift. As the blimp rises, outside air pressure decreases and the helium in the envelope expands.

The pilots then pump air into the ballonets to maintain pressure against the helium. Adding air makes the blimp heavier, so to maintain a steady cruising altitude, the pilots must balance the air-pressure with the helium-pressure to create neutral buoyancy. To level the blimp in flight, the air pressures between the fore and aft ballonets are adjusted. Blimps can cruise at altitudes of anywhere from 1, to 7, ft to m. The engines provide forward and reverse thrust while the rudder is used to steer.

To descend, the pilots fill the ballonets with air. This increases the density of the blimp, making it negatively buoyant so that it descends.

Again, the elevators are adjusted to control the angle of descent. When not in use, blimps are moored to a mooring mast that is either out in the open or in a hangar. To move the blimp into or out of its hangar, a tractor tows the mooring mast with the blimp attached to it.
