Ju 52/3M payload/range charts

[Urmel]

Does anyone have payload/range charts for the Ju 52 standard transport plane?

What I'm looking for is something like this:



Many thanks!

In actual fact, I think it might be useful to add as much other technical information as possible here, to shed some more light on the venerable Auntie Ju.

there were many versions of this plane. but this is generally correct for the type

Thanks. I am particularly interested in range/payload, because that is a measure of effectiveness to me. I have seen standard ranges of 1,000/1,100km, extendable to 1,300 with aux tanks, but the latter would presumably eat into payload. But was the former with max payload, or a reduced load?

The version I am most interested in is the 1941 production standard.

That would be the Ju52/3mg7e. The LW started the war with a mixed fleet of 3mg3e's and 3mg4e's, the 3mg5e was starting to appear for Norway, the 3mg6e and 7e appeared for April/May 1941.

For the militarised /3mge aircraft, Nowarra gives a cargo weight capacity of 4100 kgs, and an all-up flying weight of 10,000 kg...and an empty weight of 5900 kg. Maximum range from Junker's paperwork is 1500km (but see below!!!), with 1370 litres of fuel in four wing tanks and one gravity tank in the fuselage.

However - that 4100 Kgs maximum cargo capacity isn't all in the fuselage - it's a combination figure that includes the passenger area, the cargo hold rear area, the light luggage holds (not often used, and not available at all in float planes), and the four cargo holds between pairs of frame supports. The float plane versions each also had 6 2.5 cubic meter cargo spaces in 3 holds per float partly replacing the "light luggage holds" that weren't available in the Wasser version, as this was where the struts mounted.

Maximum speed 300 km/hr, max cruising speed 285 km/hr, best economy cruising speed (at 2500m) 270 Km/hr.

Fuel consumption at that "best economy cruising" was 113 litres per every 100 kilometers....or in reality ~1200km range.

Even less, once you take into account warming up, taxi, and take-off.

Many thanks!

As an aside - later marks had an extra, small third tank in the outer wing bay of each wing, but the range figures I've seen for these marks...~810 miles...would indicate only an additional 50 litres in each.

[Urmel]

Interesting, thanks. But still, nobody seems to be able to clearly answer if the 1,000km range was @ max payload.

An image from Vom Original zum Modell: Junkers Ju 52 p 24, by Erfurth & Miertsch, a delightfully Nowarra-free title, and additionally a book right down my alley since it's full of numbers:


...or 2,400 litres of fuel distrubuted in a series of main tanks ('Hauptbehälter') and two auxiliary tanks ('Zusatzbehälter') in addition, 68 litres of lubricants were kept in a fuselage tank. I wonder how much this fuel layout could be tweaked with?

The cargo door dimensions are given as 1230 x 1800 mm, not quite enough for a Tiger tank. I'm sure that's bad news in the what-if section.

Jon....which mark of Ju52??? There's definitely a jump in range (and I presume therefore fuel capacity) somewhere around the middle of its development history...there were 14 militarised marks of the 52. My figure for the four-main tanks/single auxiliary refer to the early 3mge's.

[Urmel]

Many thanks!

So the workshop Auntie had a max payload at max fuel of 2.59 metric tons. But would this also give the max range (one reason why it might not have been is that a lot more fuel would be burned during take-off and climb, I guess)?

Questions, could fuel be traded for payload? Or were there structural limits to how much could be packed into the plane?

[Urmel]

Not just Tigers. What they also found was that the Zis-3 gun could not be transported by air to North Africa. The Pak 38 could, however. Maybe two of them?

[phylo_roadking]

Or were there structural limits to how much could be packed into the plane?

Yes, and where; the maximum permissible load between ribs 3 and 5 was 400 Kg/m2, between ribs 5 and 8 it was 350 Kg/m2...and the maximum in the lower luggage holds was 350 Kg/m2.

To go back to an earlier point I raised - From Nowarra...

The experience gained in the West and in Norway with the Ju52/3mg3e and g4e resulted in further development work and the g5e version. This version was similar in part to the g4e and could be modified from landing gear to floats, but was not suitable for dropping paratoops since it could not be fitted with conversion unit F. All other versions could be fitted with the following conversion units:
E - loading device for crate transport
R - seating for 16 passengers
H - flying lecture room
St - fittings to move ground personnel
S - interior equipment to use as ambulance
F - interior fittings for paratroopers.

And if not fitted - you sat on the floor!

The g5e was followed by the g6e that could only use wheels or skis (not floats), and had a different radio - and the g7e that had a longer loading hatch.
