Boeing "Quiet Bird" 1962 Stealth project

Paul MM - Yes. A classic example of the pre-1975 problem, which was that you could design something that looked right and used the proper materials but you could never know whether it worked until you put the thing on the pole. A Lockheed scientist talking about the use of computing for RCS design in 1992 said that you could in theory get to very low RCS through building, testing, fixing and re-testing models but, as he put it, "you run out of wall-clock time".

Actually not much from what I can remember. This was the most spectacular of the lot I think!

Nothing very interesting, really. It was a place to post stuff for "Senior Members" only, mostly things people didn't want Google to index for the world to see. Not used much if at all recently. I also don't generally assign senior member status any more.

Never-Seen Photos Of Boeing's 1960s Stealth Jet Concept That Predicted The Future

For years, all the aviation world knew about Boeing’s secret stealth project from the 1960s was limited to a name and a single mysterious photo. It seemed like a relic out of time, possessing many stealthy design features that wouldn’t exist until decades later, and even then, only in highly...

Big thanks to everyone for posting all this "Quiet Bird" stuff.
 
These Images also now appearing at Boeingimages.com (from where they can be purchased etc)

The Quiet Bird was a version of the Boeing Model 853 which started out as an Army observation airplane study, this version of the 853 study was used to test materials and shapes that would reduce radar cross sections (RCS). The model was built and tested in 1962- 1963 at Boeing Wichita, these test were on a radar range and no actual flight testing was done. The tests reportedly achieved excellent results in reduced radar cross section, but it was a bit ahead of its time and did not generate interest from the military. The lessons learned on Quiet Bird probably did influence the design of the Boeing AGM-86 Air Launched Cruise Missile. Internally Boeing continued to work on the non-metallic structures aspects that were pioneered with Quiet Bird, and that effort eventually lead to the use of increasingly larger and more complex composite structures in Boeing aircraft.

Michel, welcome to Tuesday Sept 22nd... :) ;D

From the comments - seems a model has survived.

Components of the RCS model which were representative of the novelty outlined in the patents were in storage at Boeing at least until 1986.
