Max Offensive Stores for He 277 Bomb Bay?

[SpicyJuan11]

Hello, I was looking at the wikipedia article on the He 277 and it said:

In a May 1943 Heinkel factory document showing possible offensive bombload configurations and flight consumable (fuel, etc.) weights for the He 277, two differing bomb bay sizes (interior dimensions of 1.5 x 7.5 meters for the He 277's tailwheel version, and 1.75 x 7.0 meters for the tricycle undercarriage version) were considered, with the latter bomb bay configuration existing within a 1.90 meter width fuselage. The lightest warload of six 500 kg (1,100 lb) SC 500 bombs for each bomb bay configuration, gave the tricycle-geared, 1.9 meter exterior width wider-fuselage version, considering a larger load (12,200 kg/26,895 lb) of fuel, a possible stated maximum range of 11,100 km (6,900 mi), equalling the potential range capability of the earlier-designed Me 261, an indicator of what could have been achieved had the 277 been in full consideration from its beginnings for the Amerika Bomber design competition.

As someone not too knowledgeable about German bombs and bomb bays in general, could someone please do some quick caculations on what the heaviest bombload the bomb bay could handle? Any help would be greatly appreciated.

No takers...anyone? Can somebody at least please tell me the dimensions of the B-29's bomb bays, please?

Using the DB603A engine at maximum continuous combat power (which was unlikely) the He-277 had 8.97 hours endurance with a 7,084kg bomb load flying at 307kts /29,000ft. The He-277 was also designed to carry two 1,200L external fuel tanks beneath the wings, meaning range was boosted by 1,500km.

General von Barsewich noted to Knemeyer that six He-277 (He-177 B-5) were built & test flown at Zwolfaxing. Two were equipped with the DB603G engine and one with the Jumo 213F. Twelve Jumo 213F powered He-277 B-5 were scheduled for delivery by May 1945.

equipped with the DB603A engine the He277 had a service ceiling of 36,000ft
equipped with the DB603N engine the He277 had a service ceiling of 49,210ft

Sorry I can't tell you physically what the dimensions permit in terms of bombs. the maximum weight permitted would be 7,084kg.

It is worth noting 25 surplus Me-264 wings were proposed to be fitted to He-177 fuselages creating a 56 tonne hybrid aircraft. It was calculated this hybrid could carry a 3.000kg bomb load 12,500km / 6,749nm. RLM charged Hauptmann Nebel with the task of putting this hybrid into production.
