XB-15 and B-17 Pusher versions

[airman]

Interesting, it really looks like the Piaggio P 50-I Bomber (except that the Piaggio has push-pull configuration).

For me is Piaggio P 50-I !

I feel the pictures are not clear,so I repeat sending them in a good appearance.

Meanwhile, following the suggestion that was made to me in PM, here's what a pusher B-15 could have looked like.

According to Hesham's images on post#42, the pusher version model shows in-line engines. It was the V-1710 the engine originally intended for the tractor version.

BTW the link to the document doesn't works.

Unfortunately I can't find it in my files my dear Antonio !.

Unfortunately like most NASA links collected over the years...

@Antonio, are you referring to Hesham's quoted link in post#42?

Or to @Stargazer's quoted link of zephyr9900 from back in Feb 2011?

Either way, both pdfs are available on The Wayback Machine:

Many thanks Apophenia

The XB-15 tractor version drawings from April 1938 NACA report are V-1710 powered. Nice finding!

B-17 might have had better firing arcs with alternating nacelles and a thicker wing?
Outboard tractor—end of nacelle turret and vice versa…thinner waist,

From Aero Digest 1937,

so weird,they called it a transport aircraft (not bomber) ?

 

[Foo Fighter]

Loading and unloading that configuratiopn would be a trifle hazardous. Similar denomination to saying a Land Ship is an oil tank?

And just for fun the Model 299J.

Is there more detailed information about it somewhere?

 

[Antonio]

I have no additional information.
When Consolidated was ordered to help Boeing assembling B-17 bombers, in 1938, Reuben Fleet convinced USAAC that they have better and more modern design to be produced instead.
To me, Model 299J could probably be Boeing's counter offer to neutralise Consolidated's Model 32 proposal.
