It was called the "Cloudster". A prototype was actually built.

Strange to my opinion is, that this design absolutely resembles the Bell
X-22, which was launched in 1962, too. Did Bell payed a licence fee to Douglas ?
Is it actually a Douglas design ? If I look at the heading of the patent, I would
say yes, as good employees Mr.Walker and Mr.Young had to give the rigths to
their employer, but in hte references, "Doak" is mentioned ...
Well, to read such a patent is not always easy, I think ...

Jemiba - when you file a patent, you must have 'references' stated in your patent description filed to patent office - inventions patented already or descriptions of items of the common nature (i.e. from the public press). So this is a way Boeing name appears cited in cuckoo guy from Alabama patent for flying saucer, for example.

I know that Yasotay will be delighted with this last one - he loves such a stuff)

To Hesham - www.tinyurl.com allows transform mile-long urls to something pretty short.

 

[hesham]

Thank you my dear flateric,

and I agree with my dear Jemiba about the Doak
designs and that design for Douglas were the basis
for Bell X-22.

Amazing design for Douglas;

Isn't that the D-558-II Skyrocket with the orignal flush canopy design?

Indeed this is what I love about this site is that at least once a month an absolute gem appears. Until the above example showed up I had thought that the Bell series of four post ducted fans were the only extant effort(s). Thank you Hesham! The hunt is on.

Only once a month ??? ??? ??? ??? ;D

Well I did say at LEAST once a month, but that was me being my usual understating self. ;D

My dear Jemiba,

I think you could be right,that I read again about the Bell X-22,there was
a competition for the US Navy in 1962 for aircraft with V/STOL capability,
and I suggest this was Douglas proposal.

This picture already appears elsewhere on this forum; it was a project developed by Douglas with Doak.
