No - it was an entirely original Soviet design - by Petliakov.

The influence seems unmistakable: nose, hump, wing and tailplane planform, wheel housing... Petlyakov and the Boeing designers must have looked at the same stars.

Yes but don't cars all have four wheels, a steering wheel, a front engine compartment and a rear boot? But they are not all copies of a Wartburg ;). Sometimes - just sometimes - it is coincidence.

Given it only has a passing resemblance to the big-tail B-17 of five years later it’s either coincidence or Boeing copied the Pe!  For the soviets to have copied they would have needed a time machine...

Sometimes things are just “in the water” or “a la mode” like the so-called-unique elliptical Spitfire wing is seen on early to mid 30s planes from Heinkel, Seversky/Republic and many others.  Some like Supermarine just make a better/more efficient/elegant job of similar ideas.  You can bet all these designers/companies around the world were reading “Flight” or whichever magazines from each other’s countries.  And design staff moved between companies and occasionally countries sharing influences and ideas.

First of all, Max' model is great, and this is an interesting discussion.

To do Vladimir Petlyakov justice I would concede that it is coincidence for the reasons you mentioned. But a time machine would not have been necessary!

 

Pe-8 first flight: 27 December 1936

B-17 (Model 299) maiden flight: 28 July 1935

I aassume you heard about Giulio Douhet and his conception of aerial dominance.  Disputable as it is this idea was widely popular in the beginning of 30-ies and the predecessors of Pe-8 (that became "Pe" only after Petlyakov's death in 1942, before that time it was known as TB-7 or ANT-42, ANT because it was coneived in Tupolev's design bureau)  - Tupolev's TB-1 and TB-3 were built in accordance to Douhet's vision of heavy bomber.  There was nothing like TB-3 in the West that was built in numbers, There were two different directions of development of TB-3, either bigger and heavier plane, like TB-6 monster

or faster and higher flying bobmer that eventually became TB-7 / ANT-42 / Pe-8.

 

Unlike TB-3 B-17 was not designed according to Douhet doctrine, US was an isolationist state and long range of B-17 was required to operate from distant air bases such as Hawaii or Alaska. Despite the name early B-17 were relatively poorly protected against enemy fighters. 

 

My point here is that even if Soviet designers would have access to full early B-17 documentation they probably would not be much interested because 

1. in 30-es USSR was the world leader in heavy / long range plane building even despite being seriously behind in engine making

2. the concepts of aerial warfare was very different

 

What would Soviet (German, French, Japanese even British) engineers be definitely interested in is Norden bomb sight but is it not visible from outside.

The TB-6 monster is very impressive!

 

In the US, Gen. Mitchell pursued a similar doctrine like Douhet (i.e. strategic bombers will decide future wars), albeit with the Air Corps strategy being focused on long-range maritime defence. The only conceivable threat to the US continent would have come from an invasion by sea. It is true that an offensive strategy like industrial or residential destruction was not in scope. The name 'Flying Fortess' was created much later.

 

I know that Russia had multi-engined bombers already before WWI, when in the US they were still experimenting with the Wright Flyer...
