Spanish Ju-52

Hello folks!
I´m having a bit of a dilema in deciding about the Spanish version.
There are really two concepts:
A) The German Ju-52/3m g3e auxiliary bomber units brought over for the Spanish Civil War, and
B) the Spanish licence-built CASA-352 and CASA 352L units.

A) The first appear to have been about 20 units, that could carry 1500 lb of bombs.
For aerial defence, they had aft firing machine-guns in dorsal and ventral positions, the latter
in a retractable "stew pot" between the wheels.
Strangely enough, none of these had any forward firing guns Some later units had one just above
the cockpit, like the restored Ju-52 recovered from a Norwegian lake.
Perhaps they did not expect an attack from the front, or relied on escorts.

It was actually a serious weak point.

Then, as seen on some photos, two laterally firing fuselage guns could be fitted, making it into
a kind of gun-ship (apt for strafing...).
Updated paragraph:
A new model could possibly be made moving cockpit machine-gun to a ventral position, but the
parts for the "stew pot" would be a problem. I´d have to see where I can scavenge the parts for it.
Then, e
ngines would still retain their toe-out, as all these were German-built units.

B) Secondly, there were the 170 units built in Spain from 1945 to 1952. These were unarmed,
military transports, trainers, and paratrooper droppers, without engine toe-out.

However, the question is: Will a lumbering transport aircraft that didn´t drop any bombs or fire any

guns be of any interest for CFS1?
This is really the dilema.

Any ideas? I´d appreciate any comments!
Thanks in advance,
Aleatorylamp
 
Bomb hack > Parachutist...

Hello all,
and Happy Old Year´s night!

As regards the unarmed Spanish CASA 352L military transport and paratrooper
dropper, one nice idea would be to hack the CFS1 Bomb bitmap, and make a
paratrooper with his parachute out of it, and then also to hack the bomb
dropping speed, to slow it down to that of a parachutist drifting down.
Then, the bomb explosion would have to be turned into a parachutist
landing with his deflating parachute, and the crater could become a
soldier image.

That way the thing to do for the simmer would be to try and get them all
into a
certain area on the ground from a certain altitude.

There seem to be some bitmaps for bombs, craters and explosions in the main
CFS1 texture folder, that could perhaps be provisionally altered, but who could
possibly know where the bomb falling details are programmed?
It´s all wishfull thinking, isn´t it?

Here´s a screenshot - also without military markings and also without cabin
window textures as yet.

A very Happy New Year 2018 to all!

paratroops in lieu of bombs...
what a grand idea.
heck, it could even be used with the c-47.
sorry, i don't know how to accomplish it.
it would be a sight to see.

as for version preferences,
i, personally, lean toward the "lumbering transport "
and paratroop dispenser,
as oppose to the armed bomber type.
but, as i said, that's just my personal preference.

happy new year to you.
be safe
 
Hello Smilo,
It would be nice to be able to drop paratroopers...
I suppose it would be an impossible task to try and track
down the CFS variable that regulates bomb dropping speed.

Re. Spanish Ju-52: OK, better! Thanks for the feedback.
The CASA-352L military transport/paratrooper dropper it will be,
with 3x775 Hp radials and 175 mph max. speed at S.L.

It is actually a little less lumbering than the other version, the
green/yellow auxiliary armed bomber, as it has 3x50 more Horsepower.
For the moment, these two would be the releases I have in mind.

Cheers,
Aleatorylamp
 
Second gunner in!

Hello Smilo,
A little extra progress on the armed version:
The engine nacelle bulges on the wings were a bit too wide, so I narrowed them down a bit.
The glitch came from the drawings I was using. This correction also freed a few extra parts
for the second gunner´s head, which was pleasing.
Here are some screenshots. It´s not looking too bad.

Update: Getting ahead too on the Spanish version:
The narrower nacelles have also hepled reduce the difficult outer-wing/lateral-exhaust pipe,
and I also
gave the cabin area a shaded texture - perhaps I´ll give it more contrast - more
brightness and more shadow. Then, I finally started with the military markings: There´s
already
a black "X" on the white rudder.

Cheers,
Aleatorylamp

Spanish CASA 352-L trial version

Hello Smilo, Hello Ivan, Hello All!

I hope everyone has recovered from the corresponding Christmas and New Year indulgance!

To start the New Year, here is a TTV - a textured trial version of the CASA 352-L (Ju-52),
one of 170 units bult in Spain between 1942 and 1954 under licence from Junkers.

The model is very similar to the trial German JU-52/3m one I posted a while ago, with the
difference that this one is an unarmed transport and paratrooper aircraft. The engine
cowlings also have different shapes, and have air-intake scoops on top. Also, engines
have no toe-out like on the German Ju-52.

Power is 3x775 Hp ENMA Beta B4 radials (Licence built BMW-132). S.L. max speed is 175 mph.
Instead of armament, there are 18 paratroopers acounted for in the .air file, and nothing
in the Dp file, and weight is almost 2200 lb under MTOW, which should be fine.

Propellers are Ivan´s 2-pitch,(20 and 30 degrees), 2-blade Hamilton Standard, with the curves
in the propeller tables tweaked for the speed range this aircraft operates at. It is quite curious
to
watch them operating with the Beckwith Test Gauge.

The model itself has a parts count of 146.3%, despite not having a transparent cockpit.
A virtual cabin via SCASM is however planned.

One interesting thing I noticed as regards the use of left/right Wing/Nose templates, is that
they work infinetely better if they aligned with the portion of the engine that is in left/right
nose sections, (in this case the rear edge of the cowling), rather than with the swept back
leading edges. There is no momentary bleed of the engine bulkhead.

The manually made textures try to emmulate grey corrugated aluminium, light blue underneath,
with painted military numbers and emblems. Those took a long time to make. I suppose if I knew
how to use more sophisticated paint programmes, it would help!

Mostly, the flight simulator light-blue is still too strong for colouring under-surface textures of
aircraft, but looking at photos of the CASA 352L, in this case, FS light blue it fits very nicely.
I suppose the reason is that the sky in Spain is a clearer light blue than elsewhere, where
undersurfaces have to be painted in a much paler blue or even grey, the colour of more
cloudy skies.

For the moment, the exhausts are not textured, but rust-coloured. I always find it difficult to
decide how to colour
exhausts - in pictures, it ranges from bright chrome to flaked burnt paint
of different greys, browns and blacks,
or not-so-bright rust. Anyway, there are textures still free
to do something about it if anyone has a suggestion
better than bright orange rust!

Then, another fun aspect while building was the glue sequencing: With the number of items put
together with propellers and engines in the nose and nacelle sections, glue sequences had to be
quite intricate to be effective to keep bleeds to a minimum.

Anyway, here is the model and its AFX as a test version, should anyone be interested in taking a look.

Incidentally, better late than never, I noticed yet another glitch in the 3-view drawings I was using
- they didn´t show
the hump in the fuselage back a few feet behind the cockpit - they had the back completely straight! Needless to say,I corrected it as soon as I noticed, also on the other version.
Ivan had already pointed out that although the plans
seemed quite detailed, they did contain a few mistaken shapes...

I hope you like the test model! As always, suggestions and complaints will be much appreciated and
happily attended to!

Cheers,
Aleatorylamp

got it...thank you, Stephan.
the screen shots look great.
i'll try to check out the model this weekend.
 
Hello Smilo,
OK! Thanks for your interest.
Meanwhile I also found a series of pictures of two g4e specimens with a cockpit gun recovered from a Norwegian lake in 1986 and beautifully restored in a Museum in Norway and in Wunstorf, Germany.
Detailed photos with better perspective show a centred cockpit machine-gun ring position, so I can correct that. Also, more or less, what I have in yellow for the g3e bomber that served in Crete and Greece, can be black for this version, and the green can be a greyish black, so there can be two liveries of the armed version.
Cheers,
Aleatorylamp
 
Some military markings...

Hello Folks,
It appears that the machine gun fitted to a ring on the top of the cockpit was a field-mounted option on versions g3e through g6e, and as of the ge7 it was fixed, and had a glazed cupola over it.

Anyway, I now have military markings on the green-version with yellow engine cowls and rudder, as employed in the Balkans - this unit was 10/3 "J". Parts count on this model is at 148.4% now - I´ve managed to optimize resources a bit so as to get Ivan´s improved propeller blurs onto the model. This always adds some ambience!

Here are some new screenshots of the German military version!

This version is in effect a Ju-52/3m g5e, that had the more powerful Hp BMw 132-T2 engines - 830 Hp at 2400 RPM, still with 2-bladed, 2-pitch position propellers, delivering a top S.L. speed of 183 mph, and 192 mph higher up.

The beautifully restored museum units recovered from the Norwegian lake in 1986 seem to be 725 Hp engined g4e models in a darker colour scheme, which I am currently working on - no lighter colour on wing under-surfaces here, probably indicating that they were night-fliers, and engine nacelles and nose are black.

The next step will be to make a decent virtual cockpit with SCASM like we had on the Dornier 17, which should pose no problem.

Cheers,
Aleatorylamp

the weekend has come and gone
and yet another is rapidly approaching.
my apologies, but, mama's bathroom faucets
take precedence over flight sim models.
that's my excuse and i'm stickin' to it.
hopefully, i'll make the time
to have a look at your model soon.

i hate to ask at this late date,
but, what the hell...i'm old.
would it be possible and not be too much of a pain,
to have german transport/paratroop carrier
without the external guns?
don't be afraid to say know.
i'm just asking.
 
Hello Smilo,
OK by me!
No problem in taking away the guns for an unarmed logistics/paratrooper transport.

I´m having some difficulty with a camouflaged version of the corrugated aluminium
textures, so I would suggest an unarmed g5e with the green/yellow livery and the
830 Hp engines. Here is one with an authentic registration number, or so it would
seem... The only difference with my version would be the yellow elevator, but that
will be no problem.
Strange about the 3-bladed propellers, though. That would make it one of the latest
models with
the 850 Hp engines, but it doesn´t coincide with the units that were sent
to Crete.

Update: Look at the second picture I just found - the picture on the right!
It´s the same plane but with 2-bladed props.
This would be the correct one, so you will be in luck indeed!

Crazy, how one has to be careful about information on the net...

Cheers,
Aleatorylamp

The 3 planned versions

Hello Smilo,

Fine! So then, if you agree, we could plan this new collection
of Ju-52/3m airplanes as follows:

1) Unarmed transport for paratroopers, troops and logistics,
model e5g, in green/yellow Balkan campaign livery, with
3x830Hp BMW132T-2 engines and 183 mph top S.L. speed.

2) CASA 352L unarmed trainer, transport and paradropper, in
grey/light blue Spanish Air Force livery, with 3x775Hp Erizalde
Beta B-4 engines and 175 mph top S.L. speed.

3) Armed transport unit model e4g as recovered from the Norwegian
Lake in 1986, with dorsal and cockpit machine guns, in night-flier
camo livery in dark-green / khakhi-green / black, if it comes out
OK, with 3x725Hp BMW132-A3 engines and a top S.L. speed of 165 mph.

I think it will be best to discard the eg3 auxiliary bomber version,
as was used in the Spanish Civil War and against Austria. This model
turned out not to be useful for WW2, and was only a stop-gap until the
Dornier and Heinkel bombers became available, and most of the Ju-52/3m
auxiliary bombers were re-converted into transports.

Apart from weak defensive armament, it required the bomb-aimer to be
in a cumbersome retractable "dust-bin" underneath the plane between the
wheels. It was the only place to get a good view of the objective, and
was also the defensive ventral aft-firing gunner position, but was quite
laborious to extend and caused a lot of drag.

This "dust-bin", also called "stew-pot" or "night-pot", was eliminated on
subsequent models, except for 12 e4g units that were turned into gunships
or bomber escorts, with 5 machine guns: dorsal, cockpit, lateral and ventral.

There aren´t enough parts left over on the AF99 model to make this "dust-bin"
and its inhabitant anyway, so I will leave it out.

So, if you think this is a good plan, we can go ahead with it!
Cheers,
Aleatorylamp
 
Possible transparent cockpit

Hello Smilo,
Thanks for confirming!

Your German yellow-green unarmed transport is done, and as parts
count is now only at 135%,
I was thinking of trying to make a transparent
cockpit for it,
with two inhabitants, similar to what Ivan helped me with on
the AT-9 Jeep, but perhaps without the seat-backs.

With 120 parts to
spare now, and a few structures and components,
it may work out very nicely.
By the way, this is not possible for the
CASA 352L - the parts are taken up by the
supercharger air-intakes
on top of the engine cowlings and also the bullet-shaped antenna on
the roof, which the German version
doesn´t have.

Incidentally, for the CASA 352L, I just found out that the Spanish
Erizalde B-3 (750 Hp) and B-4 (775 Hp) engines were not licence-built
BMW132´s (i.e. Hornets) at all, but licence-built Wright Cyclone R-1820´s.

So when they ran out of German BMW132´s, they used those, as
Erizalde had the licence to build them.


To differentiate between previous CASA 352 units with the German
engines and the later Spanish ones, to avoid confusion with spare
parts, the CASA 352 nomenclature changed from T.2 to T.2B, as
the Erizalde engines had metric measurements.


The Spanish Air Force also had a number of identical 700-800 Hp
Shvetzov M25, Russian licence-built Wright Cyclone R-1820 engines
for their Polikarpov Rata / Mosca fighters, so the mechanics were
familiar with it. Cylinder displacement and Compression Ratio were
slightly higher, which would account for the higher power output.


I have modified the engine parameters accordingly, for the .air file
of the CASA 325L, just for the sake of accuracy, although previous
performance, also with 775 Hp, is basically the same.


I´ll also modify the engine bitmap, as this one didn´t have the gapped
circular cover infront of the engine housing.

Cheers,
Aleatorylamp
 
Unarmed Transport model - WIP

Hello Smilo,
I just thought you would enjoy a preview model of your
unarmed transport, the green/yellow 1Z+IK, while I try
and make the transparent cockpit and do the virtual
one for the upload version.
Note the Lufttransportgeschwader 63 emblem
on the nose! ...(Air Transport Wing 63).
Enjoy!

Update:
Preliminary trials for the transparent cockpit result in insufficient
parts for pilot and co-pilot figures - there can only be one pilot.
This, apart from the bleeds, which I´m figuring out the glue
sequence for, or rather against... is the present situation.
Is it worth pursuing if there is only one cockpit inhabitant?


Cheers,
Aleatorylamp

thank you, Stephan, i've got it.
am anxious to check her out.

as for the transparent cockpit
with only one figure;
i'd say yes, please give it a go.
i'm sure you're well aware,
there are many models out there
with no crew at all.
