XB-15 and B-17 Pusher versions

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) ?

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