thanks again BT~wasted !

Installed/ wrorking just fine in BAT 3.3.5 - the MANPAD, Gaskin and SAM site items...one question though?
---you mentioned the 'mobile' unit (Gaskin') can be in the soviet convoy. Is it SUPPOSED to be part of one ModSoviet column after installling the files/text, os di you mean the individual Mobile unit?

thanks,

xAx

to Koty:

no, they are not movable of course. If there would be 3d models of the moving vehicles, I would include them, but unfortunately I don't have them.

to xxxautoxxx:

You need to edit your Chief.ini in the section with modern soviet columns.

You can replace your lines of [Vehicles.SovietModernCarsColumnB] with the one that are provided in the first post, and also you can add the Strela 1 to any column by adding this line in between other vehicles:  com.maddox.il2.objects.vehicles.tanks.TankSAM$Strela_1M

I had a WIP model for what I believe to be Volkhov launcher. I could try finishing it (using existing textures), but it has no LOD's

The Strela is great fun to evade, it usually misses by a few inches only.  o_O
But can be fooled, by flying from sun.  8) Just like any good heat-seeker.

Now, the V755 itself...

The issues are:
Too high in-flight G limit
Too low turn-induced drag
Too high thrust impulse (60kN for 30 seconds)
Possibly wrong guidance method (command guidance would act as beam-riding with lead)

I'll see what I can do.

Please share source codes on superschool SVN !  :)

In my memory, S-75 objects are also 3d re-modeling needed as same as Strela-1 model ---- pended because of no proper guidance codes = no need to make.
When well done codes will come, I'll try those 3d works again before whole set publishing.

Sources uploaded to SVN!

EDIT:

btw, looking at your SVN sources of latest Engine Mod I see that you have started to work on proper RWR codes incorporated in ground object classfiles. I am wondering if there is any kind of documentation on that matter?

I have a question, is the ZSU-23 installed necessary for proper operation of the Strela-1M?

Hi Guys,

Working in IL2 4.12 non Bat, JTW modact 5.3 with Latest engine mod and USMC pack.
S-75(SA-2) fires and locks on after 1800 ;) RWR works with aircraft with the code, chaff decoys working, stationary SA 2 and NIKE separate from this mod working well when used in a mission together with "*" warning and RWR working separately however the SA 2 and NIKE do not like to lock on or work correctly after 1800. no conflicts detected with other mods so far.
Strela s working fine.

S-75 destructive power I think needs to be increased, when close, behaves like SA 7Strela/SA 9. Chaff working ;D

Thank you for this great mod best of luck.

Finally gotten around to testing the latest release.

Works really well, also, the parameters for V755 seem to agree with what I've been able to find for the most part.
Now, rest of the things I could find:
The proximity fuse should be able to work out to 100 m.
Booster has specific impulse of 100 000 kgf for approximately 3.85 seconds (average, it would normally depend on temperature), so force should be 255000, timeFire 3.85

I have a bit different data:
http://sovetarmy.2x2forum.com/t39-topic

according to that link powder booster thrust is 27000-50000 kg for 3-4,3 sec.

Rocket engine thrust is 2650 ±130 kg for 34 - 40 sec.

That's what I set for force parameter.

Might be I am misunderstanding about how the force value is calculated.

I see the numbers...

you take the desired impulse (as stated in the post you linked, 100 000 kg is minimum) and divide it by burn time. Assuming 50 000 kg of thrust for the shortest time quoted - 3 seconds - you already get 150 000 kgs impulse, which is 150% of the minimum - a bit too high. Although the difference here doesn't make the missile much different.

Also, try setting the power type to 1, tends to give me bigger effect for in-air explosions.

Thank you.

I'll look into them.

I've not written any documentation yet.

What contents / How detailed documentation do you need ?
I'll write it in 2 or 10 days (due to detail level).

Briefly ....

A search radar detect an aircraft having RWR ----> call ((TypeRadarWarningReceiver) theAircraft).myRadarSearchYou(Actor actor of the radar owner, String soundpreset of Modulated sound Radar Wave)

A CW radar (Illuminator) lock on an aircraft having RWR ----> call ((TypeRadarWarningReceiver) theAircraft).myRadarLockYou(Actor actor of the radar owner, String soundpreset of Modulated sound Radar Wave)

Only those 2 methods about aircraft side RWR.


SEAD missions with Anti-Radiation missiles need another set of information giving ways on ground radar objects.



By the way, ground missile station class has to operate not only SAM but also ATM / SSM and family with ship base system Tartar / Terrier / Talos / Sea Sparrow / etc.
When ATM (SACLOS) implement will be done, I can add 9P148 vehicle (BRDM-2 variant with 9M113 ATM's launcher) soon.
