He 177/277
Re: He 177/277
The He 274 were built in France during the war (like so many aircraft) and finnished after the war by the French.
They indeed somewhat look like Wright R-3350's and probably like any other radial which they (DB603 were Inline V12 engines) were not! but those are not so rounded (and missing the intake).
They could have changed the engines (or did the AAS01A had different engines vs the AAS01B)
(have to check Heinkel He 177, 277, 274: Eine luftfahrtgeschichtliche Dokumentation if there is anything about that in it).

Re: He 177/277
I have openly stated that it was photoshopped so as not to deceive anybody. It is ment only to illustrate and inform.
To the best of my knowledge* the He 274 prototypes used DB 603A engines with Bosch TK11 turbosuperchargers which then became designated DB 603S. They had annular (ring) shaped radiators making them appear like radial engines. The French had a deal of reliability problems with them. I gather these engines had 40 hours TBO.

Re: He 177/277
Yes much appreciated thanks. Some of the French experiences with the He 274 are hard to come by so photos are a bonus. I wanted to create a website on the He 274 / He 277 and needed some illustrations of the He 277 B-5.Ome_Joop wrote:I noticed but i thought these were better.I have openly stated that it was photoshopped so as not to deceive anybody.

"Heinkel He 277B-5" is an invention by past aviation historians for the Heinkel He 177B, which had four separately arranged engines in contrast to the baseline He 177. The Heinkel He 277 was indeed derived from the He 177 and had the same number of engines as the He 177B, but differed in having a bigger wingspan and a glazed nose section similar to that of the Bristol Blenheim. Info about the He 277 is found at:

Re: He 177/277
Hi,
I recently got a copy of "German Luftwaffe Prototypes 1930-1945" and it's clear that the first and second He 177B prototypes had the serials NN+QQ and GA+QQ respectively, while the incomplete He 177B prototype V104 was assigned the serial KM+TE. One side view of He 177B V101 (see https://sites.google.com/site/heinkel277/home/he-177b) oddly shows it with the block code NE+OD rather than NN+QQ, so it's possible that someone doctored the only photo of the first He 177B prototype to have the block code NE+OD placed over the faint lettering on the rear fuselage because the code block series "NE+Ox" was assigned to a batch of production He 177A-3s and the first He 177B V101 was converted from a production He 177A-3. Rumors that the first He 177B prototype was re-engined with Junkers Jumo 222s judging from pictures of the destroyed V101 at Cheb, Czech Republic, with four-bladed propellers similar to those driven by the Jumo 222 are false due to the number of engine stacks differing from the Jumo 222's; the outline of the engine cowlings is identical to that of the Focke Wulf Fw 190C prototypes and first five Heinkel He 219 prototypes (https://en.wikipedia.org/wiki/Talk:Heinkel_He_277).

Re: He 177/277
If people want to know what would have happened if the Heinkel 277 would have been mass producted and operational I suggest to read aviation historian Mike Spick Luftwaffe Victorious book.

Re: He 177/277
The Heinkel He 277 was only intended to sink Allied supply convoys in the North Atlantic and would not have had the range to reach the US , as noted in the Secret Projects Forum. Therefore, if the RLM had decided to clear the He 277 for full-scale development, the He 277 would have wreaked additional havoc on Allied vessels in the North Atlantic along with the Ju 290.GAUM1983 wrote: ↑13 Jan 2020, 15:32If people want to know what would have happened if the Heinkel 277 would have been mass producted and operational I suggest to read aviation historian Mike Spick Luftwaffe Victorious book.

Re: He 177/277
Unlikely, since by the time it would be ready for deployment, the USN and RN had a number of merchant and escort carriers in service. Even an FM 1 or F4F Wildcat could take on an He 277, particularly one that is alone, and shoot it down.Cantankerous wrote: ↑02 Jan 2023, 05:48The Heinkel He 277 was only intended to sink Allied supply convoys in the North Atlantic and would not have had the range to reach the US , as noted in the Secret Projects Forum.
