Heinkel 177 A7 R2 - an alternate version

[airman]

"The Heinkel He 177 Greif (Griffin) was a long-range heavy bomber flown by the Luftwaffe during World War II. Purpose-designed for high-altitude bombing with pressurized crew accommodation.
The He 177 A-7 R2 variant was intended to use original "power system" engines, each of which consisted of two combined BMW 801G 14-cylinder radial engines, each mounted in an individual nacelle and each turning a contra rotating-blade, four-meter diameter propeller."

How do you intend to cool the rear BMW801 engines?

 

[riggerrob]

Structurally, your can build lighter wings with 4 engine nacelles than 2 nacelles.
Spreading engine weight along the wing span recues point-loading, allowing for lighter wing spars.
Four nacelles also simplifies engine cooling especially with radial engines.

I understand that. But putting one air-cooled radial behind another means that the rear engine gets heated air rather than cooling air. On the Pratt and Whitney R-4360, which was designed as a four-row radial with some very complex baffling and careful arrangement of cylinders to insure cooling of the last two cylinder rows. Even so, it had overheating problems that took a long time to solve. I doubt that one could simply stick one two-row radial behind the other.

The DB610 consisted of two liquid-cooled V-12 engines geared together side-by-side. As it happens, it did not work well and caused well-known problems on the He177.

It's an alternate version of Heinkel 177 with paired BMW 801 instead DB605

How do you intend to cool the rear BMW801 engines?

it's an art of haryopanji : an ipotetical two paired bmw 801 engines like DB 610 . If see of description have 4-bladed VDM constant-speed contra propellers

I understand that. But putting one air-cooled radial behind another means that the rear engine gets heated air rather than cooling air. On the Pratt and Whitney R-4360, which was designed as a four-row radial with some very complex baffling and careful arrangement of cylinders to insure cooling of the last two cylinder rows. Even so, it had overheating problems that took a long time to solve. I doubt that one could simply stick one two-row radial behind the other.

The DB610 consisted of two liquid-cooled V-12 engines geared together side-by-side. As it happens, it did not work well and caused well-known problems on the He177.

Surely art of haryopaniji don't consideer or not mention to complexity of Heinkel 177 project like airbrakes for dive . Because Someone (Goering ) liked sophisticated airplanes with all problems related

Didn't make clear if the BMW 801s were arranged. No good way to run them in tandem, due to how they were aspirated, as well as the previously mentioned cooling issues. BMW had a real 28 cylinder engine, the 803, though not just two '801s stuck together. Might be possible to have side-by side engines buried in the wing, like the Bristol Barbazon. My own "wiffy" version would use tandem DB605s or 603s with the rear engine running its drive shaft though like a motor cannon (Several countries tried variations of that kind of tandem engines) and each engine running an independent contra-prop.

I imagine that BMW 801s would have been installed conventionally, as four separate tractor units, as on the He274/277.
