Ju 52/3M payload/range charts

Well, that settles that Thanks Snautzer! A few inches from the main flaps, then....

Do you happen to know when that configuration came into play? Or was it the original layout from the very first /3mge versions?

[phylo_roadking]

Cargo hold - the text uses the term 'Hauptnutzraum', or 'main utility space' so presumably the 19.3 cubic meters apply to the entire cargo hold area.

...which is slightly smaller than Nowarra's figure of 19.6 m3.

[Snautzer05]

Sorry, I've just scrubbed that, having a brainstorm!

You'd need to check that the aircraft physically could accomodate two or more 38s...

gun weights 830 kg with that kind of weight you have to take centre of gravity in account. with 2 of those guns it would make it too dangerous. Not the weight itself but the distribution of it.

[phylo_roadking]

That's a good pont! I'd figured out the weight distribution bit, but didn't cotton on to the C-o-G issue.

Although - if you could stable a horse (approx. 450 Kgs) in the rear portion of the aircraft...

Does your paperwork say anything else about lading factors etc? I'm presuming there was some way of re-trimming the aircraft for problems like this...?

original layout

[Snautzer05]

weight of the gun is centred between the wheels. horse is spread over its 4 legs. Although i do not think it would have been a big horse as the cargo doors are not that big.

Germans had a simple solution for guns. see pic. Strap it under

...but if you look closely ( and noting Jon's earlier comments) that's for paradropping, you can see the bundled parachute. I guess using the same mounts as paradropped supply containers.

[Snautzer05]

Point is that if it didnt fit inside .......later on the did the Dobbas cargo container (also on other airframes) as a more Ikea kind of solution

text belonging to the pic note the "sometimes"remark

[phylo_roadking]

I'm not sure if it's a case of it not fitting inside - the leichtgeshutz 10.5 cm LG 42 recoiless would have fitted inside, no problem....quite titchy, actually -



...but it would have been a bugger getting it back out again in mid-air to paradrop! It was after all just an upgrade of the 75mm LG 40....which the FJ had dropped and used on Crete.

Vom Original zum Modell: Junkers Ju 52 p 24, by Erfurth & Miertsch

Jon - I've got to the bottom of the missing fuselage auxiliary...

From the Zivilversionen edition of the same book...the fuel system for the Ju52/3m Note tank number 5! I presume it was deleted in the first /3mg3es of 1935....for the bomb cells?

[Jon G.]

Phylo, tank #5 is the lubricant tank.

[phylo_roadking]

Jon, I don't think so - the disgram is specifically titled "Kraftstoff..." - "fuel"

Tank number 5 also plumbs into the rest of the fuel system at Point 11. - "valve assembly"...so unless the BMW 132 has suddenly become a two-stroke....

Its "50L" is also counted into the "zus. 2450L" fuel tankage total there...(I presume "zus." is short for "zusammen")

[Jon G.]

Right, upon closer study of your scan, tank #5 reads as a 'Fallbehälter', or waste tank, rated at 50 liters. and connected to the fuselage-mounted hand pump.

That doesn't make it a fuel cell, though, missing or otherwise.

[phylo_roadking]

That doesn't make it a fuel cell, though, missing or otherwise.

Except, as I noted while you were posting - its 50 litres is counted into the 2450 litres total fuel capacity on that diagram.

I know it's only Yahoo babelfish - but there, Fallbehälter tanslates as "Gravity feed tank". From Nowarra, for the Ju52-3mge -

Fuel storage: 4 tanks in each of the outer wings; 1 gravity tank in the fuselage

P.188

[Jon G.]

Tank capacity, not 'fuel' capacity. Note that other specs - including the scans provided by Snautzer05 - give Ju-52 fuel capacity as 2,400 litres, coinciding neatly with the total storage of the wing tanks.

Since we already are splitting hairs, and since no-one but you has been looking for a fuselage fuel tank, perhaps you could tell us what the deletion of a 50 l. waste tank, apparently located in the cockpit, would mean for a/overall carrying capacity of the Ju-52, and b/overall range of the Ju-52?
