Triton said:The Lockheed Martin P-791 is an experimental aerostatic/aerodynamic hybrid airship. The first flight of the P-791 was made on 31 January 2006 at the company's flight test facility on the Palmdale Air Force Plant 42. The reason for the construction of the P-791 is unknown but some observers believe that it might have been developed as part of the DARPA Walrus HULA project.
AeroFranz said:Well, so far all manned airships have been limited to about 10,000 feet cruise altitude (some Zeppelins flew higher during WW I). I guess you could pressurize a gondola and fly higher, but then statistically you find higher windspeeds, which are very bad for airships.
Simon666 said:Is it just me or does it really look like it has the shape proposed by Goldschmied for wake propulsion?
Avimimus said:I've often wondered what would happen if you placed a metal mesh underneath an airship. It might still remain vulnerable to high calibre/high velocity artillery, but it would temporarily negate the effectiveness of most missiles (until ones are developed with two stage warheads at least).
Aerospace companies typically produce program fliers for distribution to potential customers at trade shows. These fliers include a photo or artist concept of the program with key details on the reverse side. This 11 X 14 inch data flier describes the HIGHSPOT program from the early 1980’s, a high altitude blimp technology predecessor to the modern RPV. It is in very good condition. I will be shipped rolled.
