"Naval Air Systems Command 1975" is not a source, Hesham. Amend with the actual details.

OK my dear PaulMM,

I will correct it.

OK my dear PaulMM,

I will correct it.

Thanks - I updated the original post with a link.

Thanks - I updated the original post with a link.

Thank you my dear PaulMM,

and what about Rockwell NA-410 ?.

Thank you my dear PaulMM,

and what about Rockwell NA-410 ?.

Don't see a question? What about NA 410?

 

[hesham]

Could be a misprint ?.

 

[overscan (PaulMM)]

Why?

We know of NA-420 / NA-430 / NA-431 Type A V/STOL designs.

I don't believe we have a different ID for NA-410, so why could it not be another V/STOL Type A design?

Rockwell also has under study several candidate Type "A" designs. The NA-410 design is powered by four turbine engines connected to four lift/cruise fans which are mounted in wing pods.

OK my dear PaulMM,and that's new,we missed number 410 in the list of North American/Rockwell.

I'm well aware we have dozens of posts already in the existing US VSTOL Projects topic, but I want to split that one up a bit. Therefore I'm creating this topic, with an image from NASA Glenn image archives.

Same image enhanced from better quality version at National Archives.

Alas, the only substantive part of the program is rotting in the back of Moffett Field, CA.

Ah yes, my first 'paper airplane' assignment, only months out of college. I speak of Design 698-309 dated June 1976, our initial Type A configuration, as drawn by Tony Bacci and directed by Bob Kress. I had the very good fortune to have Dr. Wolfgang Gunther Buchmann as my lead engineer and mentor.
The NASA-Ames model is a later configuration, reflecting a proposed flight demonstrator design. The last version I worked on was Design 698-411, our baseline submittal responding to the Navair's 1977 RFI, in support of the Navy's development of the Sea-based Air Master Study (SeaBAMS). Grumman management incorrectly presumed (or maybe just wished) the RFI was the precursor to a formal program launch. Can't recall by 1977 if we had yet ditched the canards and the engine-hinge scheme off the wing front spar (not sure what Kress was thinking). Thanks for posting.

Here's what was probably the primary Sikorsky response to the Type A requirement. Ultimately was not officially submitted.

Is there any more information about the Sikorsky project? The link here is dead and I swear there used to be an image of it posted directly here

I'll see if I can track it down during the coming week.
