The Northrop N-31 Cargo flying wing concept

[McColm]

I've just seen a line drawing of the Northrop N-31 cargo flying wing concept and immediately thought of the XB-35 . This looks as though the nose and the tail are from a Boeing B-29 or B-50. A four engined or twin engined using contra-rotating propellers,  although the wings are swept back on the N-31 to 37° and looks remarkably similar to the Convair flying wing sketches.
I think that I can build this but it will be a future whiff.

Thanks to direct us to this.
I found pictures at https://www.secretprojects.co.uk/threads/northrop-n-31-and-n-31a-flying-wing-bombers.5219/

In the site above, I found no date of project N-31 but, looking in the archives, I discovered that the preliminary N-031 was dated 1945:

Thanks for the information

The date is not information but what-if joke from imagination "archives", but the secretprojects site is serious
