Lockheed Martin P-791

The P -791 is an experimental hybrid airship, which was developed by Lockheed Martin. The maiden flight took place at the company's own test facility on the Palmdale Air Force Plant 42 on 31 January 2006.

The design of the hybrid airship

P -791 is an example of a hybrid airship. In such constructions, the weight of the airship and its payload is sponsored jointly by static and dynamic lift. This is an attempt to achieve " the best of both worlds " combination.

Critics of this interpretation " the worst of both worlds " called as a runway for takeoff and landing is required, which would not be necessary in purely static buoyancy. Proponents believe that the previous stumbling blocks could be removed through the use of new technologies.

The fact is that there have so far only managed a few hybrid airships from the drawing board in the experimental phase. One of the few vehicles that have risen up in the air, Aereon 26 The development of this aircraft has been documented in the book The Deltoid Pumpkinseed by John McPhee.

Lockheed -Martin developed a proposal in which probably were incorporated experiences with the construction of the P -791 for the DARPA WALRUS project. This allowed the company to gain a competitive advantage over its competitors. 2010 WALRUS project, however, was already set by the project definition phase I. Critics noted that the interpretation of the P -791 also strongly resembles the earlier skycat, which was developed by the British company Advanced Technologies Group ( ATG). In fact, the P -791 project former employees of the ATG are busy.
