MANPADS Missiles and Overload: The Technical Details

9m39 has a miniature explosive gas-turbine power system instead of a battery (or alongside idk) which provides power to the systems. A byproduct of this is hot, high pressure exhaust which is directed out the sides of the missile. Internally there is a solenoid which alternates exhaust ports, which when combined with the spinning motion, gives a pseudo thrust-vectoring for the early stage of flight before the fins start becoming effective.

That is not what the missile is doing. It’s essentially the same thing the Tor-M1 does, except instead of a 90° turn it just points directly/leads the target. The missile even having this capability is what is in question

We went over this already in this thread, but yes there is photo evidence of this system being present and it is specifically mentioned in the manual.

It’s been a couple of months, but I don’t remember the manual stating the thruster was specifically for this sort of “first turn” capability. I thought it was ambiguous and just as easily could have been to simply impart the spin on the missile

Google translate technical speak makes my brain hurt. And at least based on that it says 2 different things.

This video is much more definitive in my opinion. This first one, the “required angles of advance and elevation” as the manual puts it are so minimal it almost looks like just the missile falling with spin. Here I can also make out the “kick” from the motor that stops the missile right on its line.

All that means to me is even less reason for them to blatantly lie and ignore primary sources for Western MANPADs then.

Seeing this new information come to light, have the Developers considered what effects the 9M39’s turbine generator may have on in-flight maneuverability?

Does it provide the hydraulic force for the fins directly? Does the gyroscopic force matter at all? It is my understanding that this system is entirely unique to the 9M39 and 9M313, and is not present in any form on Western MANPADS.

Yeah, FIM-92 automatically tells the gunner where to lead it, and I’d wager that Mistral does too. Just one of those things that isn’t modeled.

This is a great example video, shows the gas generator impulse off perfectly.

Seems to me that in-game the effects of the gas generator are a bit exaggerated, though.

Which I searched for sources on and couldn’t find any describing that it takes THAT long for said NATO Manpads to initiate maneuvering. The literal only source I can find is that it is armed and control kicks in 9 meters away from the launcher.

We know that Stingers are ejected from the launcher at 100ft/sec (~30.5m/sec) and so traveling that distance takes a minimum of ~0.30 (9/30.48) seconds.

Make a bug report about it, having guidance right off the rails will make them usable.

Do you remember what translation tool you used (or whoever made the images) used?

I used Google translate, the images originate from a Korean website, and were in Russian

Has anyone else here noticed that in the past update or 2 Stingers love going for flares?

Does google translate have an image feature?

Yep, they have one for full PDFs too

Dang, it stopped me from looking at non-text stuff for a while. Glad to know there’s (free) software for that now.

im fairly sure this has been extensively discussed already

Its because in the grand scheme of things said generator is not actually imparting any lead or yaw, its the fins pulling lead as needed, hence why the actual lead imparted is so much less than what we have in game.
