Hesham, first one was one of alternative Lockheed CX-HLS (C-5) design, discussed here for a while.

It's hard to see for me, what idea was saved with this patent.

It's a "design patent." It's a much simpler kind of patent, covering only the shape or appearance of an item. That prevents other companies from building things that look the same. Take, for example design patent D260789. It may be familiar.

A very similar design, but powered by turbofans, not turboprops,
was obviously proposed by Lockheed in 1966
(from Flugwelt 1/1966)

It's a "design patent."

Many of the Northrop patents I've found have been "Design" patents. Isn't part of the reason for doing this kind of a way to patent an aircraft design, without "revealing" specific features they be trying to protect or may be classified?

BTW, I've never thought to ask this, but are there "Classified" patents? I'm not quite sure how that would work, or is it just the fact that something may be secret that nobody else "supposedly" knows about it that protects the "design/feature"? I was just wondering how you patent protect something that is secret, and if it's secret, what does it matter, because nobody else can know about it. In which case, what if someone develops something very similar in the non-classified world without knowledge of the classified version. What happens then?

Well, the DP only really protects shape and appearance. However, you can protect the sha[pe and appearance of something without *really* giving it away, if you are sneaky. Like, for instance, the Bird of Prey patch, which was shown publicly well before the actual aircraft:
180px-BoP_Patch.jpg


Had Boeing done a DP on that, they would have the BoP's shape protected, without actually letting people know about it.



BTW, I've never thought to ask this, but are there "Classified" patents?

No. If it's patented, it gets published. If you have something classified, you don't get a patent on it until the classification has been reduced. I've seen patents applied for during WWII that weren't granted until the 60's and 70's.

Hi,

a strange helicopter to Lockheed.
http://www.google.com/patents?id=XnAtAAAAEBAJ&printsec=abstract&zoom=4&dq=lockheed+helicopter#PPP1,M1
Reading the patent abstract is sounds very much like the NOTAR system, right down the elongated slot(s) running down the tailboom to induce the downwash to provide an antitorque force. Did Lockheed invent the NOTAR system? It seems that patent is dated 1974 and I was under the impression that NOTAR came along much, much later than that via Hughes/MD Helicopters.

The ' very strange aircraft ' found by Hesham is probably
the patent drawing for the Lockheed GL 224-2 project
leading to the Hummingbird
