The flight deck's instrument panels, overhead console, and associated wiring had to be reinstalled.
[On] May 11, 2017[,] Wednesday evening Airlander 10 completed its first flight since the giant dirigible crash-landed nine months ago. The airship took off at 5:28pm, puttered around for almost three hours, and successfully landed at 8:15pm. …
The new auxiliary landing system… worked perfectly.
HAV says that [the] successful flight recommences Airlander 10's three-phase flight test programme. For now, Airlander 10 isn't allowed to ascend beyond 4,000 feet or travel more than 15 miles from its hangar in Bedfordshire. As it progresses through the test programme it'll be allowed to travel farther and higher and stay airborne for longer. In theory, Airlander 10 can hang around for a few days. [Five days in most reports]
Lockheed Martin is currently assembling the first 15 of its LMH-1 hybrid aircraft — so called because they generate lift with both a lighter-than-air helium envelope and aerodynamic surfaces — at a plant in California, with the earliest expected off the line in 2018 or 2019.
With vertical take-off and landing, the airship will be able to carry cargos up to roughly 47,000 pounds without requiring a runway. Moving at a top speed of 65 miles per hour, [Ron] Hyde [PRL Logistics CEO] said the craft is best thought of as “not a slow plane, but a fast boat.”
The hangar Hyde plans to build at PRL’s Kenai center is also in the conceptual stage. In a presentation to the Kenai City Council on April 19, he estimated its cost as $10 million…
“It depends who’s piled on to that number,” Hyde said. “If you take Lockheed Martin, maybe they want to have a simulator, or the ability to completely rebuild the entire engine, or maybe they want to do a lot of things locally rather than waiting for parts to come in from LA.
Hyde said putting the airship near a busy airport like Anchorage’s would be “the worst thing we could do.”
“We knew that putting it at any airport was not a good option, because it flies so slow,” Hyde said. “And the whole purpose of the ship is not to be restricted to a commercial airport.”
A dynastat is a hybrid airship with fixed wings and/or a lifting body and is typically intended for long-endurance flights. It requires forward flight to create the aerodynamic lift component.
CONTROL OF STATIC HEAVINESS (COSH)
Unlike other airships, the Aeroscraft is the only air vehicle designed with the patent-pending control of static heaviness system that controls the vehicle's buoyancy to be heavier-than-air during ground operations or lighter-than-air during flight, acting as a “flying submarine.” The control of static heaviness system internally ballasts the non-flammable helium into the aircraft’s helium pressure envelopes (HPEs).
