Boeing "Quietbird" and the "YF-113G"

New topic

No outlandish posting of speculative images this time.  I should have known better than to have put forward anything like the "flaming pumpkinseed" thingy - like pouring gasoline on a fire.  Any information on the Quietbird from Boeing or on the
YF-113G.

Yes. We have photos of the Boeing Quiet Bird mockup posted in a forum section visible to senior members. Its a 1962 project for a reduced RCS Army observation aircraft. Not well known, but not very secret, and not built.

any chance you posting the image or images of Quietbird?

Thats really up to Scott. Here's the patent though:

A tiny side view posted on Scott Lowther's (I believe Mr. "Orion" to you?...) excellent site:

Predates apparent known use of YF-113G designation by some way though.

I don't think they are connected. YF-113G is a cover designation for another program.

Quiet Bird predates the designations that include YF-113G.

Could the Quietbird be seen an progenitor to the Bird of Prey or was it a different developmental pathway due to the McDonnell Douglas origins of the Bird of Prey?

Take a look at the patent, especially at the date...

Here is a little comparison between the Quiet Bird, the X-36, the Bird of Prey and the YF-23A.

I doubt that the Boeing connection can be found directly in the other three as the two companies merged less than two decades ago.

However, I believe that preliminary research on the Boeing article probably led to very precise specifications for all subsequent research aircraft based on what it helped to investigate. This could perhaps explain the relative similarity of certain features.

As an aside, I include a stretched version of the Quiet Bird (photo resized with no aspect ratio maintained). You'll see that it makes the design connection even more visible between the QB and the more recent projects.
