Experimental Flying Wing Bomber
« on: February 14, 2020, 07:00:33 AM »
Starting build of Experimental Flying Wing Bomber (XFWB).  Not pure flying wing only because has nose section.  Is to be 1940-ish proof of concept akin to B-15 & B-19.  Combining YB-49 and front of Ki67 because it has matching cross section height to YB-49 and is sleeky.  Eliminating jet engines, replacing with puller props.  Looking at engine possibilities so that is TBD.  Building wing and nose first.

Attached pictures show jets cut out, filling leading edge air intakes, and start of filling openings in wing.

Thanks all,,,   does build simpler than Mega-carrier, still it has nose section fit things to deal with.  Plenty PSR.

Figured out different vertical stabilizers.  Trying piston engine mounts, for swept wing..... they be asymmetric.

Progress  ---  Basic wing assembled.  Doing PSR&R&R....  Three of six engines built.  As seen in attached picture am going with four B-24 rudders.

Some possible inspiration - Boeing Flying Wing concepts from the mid 1930s.  They are all variations of the same theme and come under the Model 306 designation:

Me too! It's almost frightening how well parts that shouldn't belong there work.

That Boeing design looks like early B-17 cockpit, DC-3 wings and Allison engines....... Mucho PSR!!!

Those concept drawings ARE INSPIRING.  Appreciate your finding-posting them.  Sweep is similar to B-35/49.  One of you model companies following this topic ?

Was comparing B-49 with built B-17.  With careful cutting & PSR B-17 cockpit can be fitted.  Used one on PBH-417 build.  http://beyondthesprues.com/Forum/index.php?topic=2179.msg30402#msg30402

Thanks for your comments.

Back at it.   Nose glued to wing.   Right inboard engine glued.   Others taped for picture.   Fine tune filing (much as practical) engine to wing mounts.   Each engine needs three axis alignment.   Then PSR edges of nose and engine mounts.

Inboard prop has 27 inch clearance to nose.    Can now see would work with four engines, going with six already prepared for mounting.   Stabilizers not glued.

see attached pictures

Oh yes what a fantastic flying wing, fins!

Looks wonderfully sleek and sharp.

I'd be tempted to call it the Arrowhead.

Looks like she's using Allison V-1710's. Are they going to be modified for high altitude or is she going to be low-altitude?

Yes.   Those are P-40B engines-cowlings on this Curtiss one only experimental bomber built in 1940, first flying in Spring 1941.   Good question and point; supercharger intakes in wing leading edge distanced from exhaust flow would be appropriate for high altitudes.

Became a ten kit bash.   YB-49,  Ki-67,  2x B-24,  6x P-40B

Now that I see what you see in pictures am encouraged to move along to timely completion.   Appreciate the comments !

Are you going to give it a yellow (flying) wing scheme?

I'll get me coat.

Very nice kit bash. The B-24 fins really give it a late 30's early 40's feel.
