MANPADS Missiles and Overload: The Technical Details

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.

Can somebody tell me whether I should be seething regarding this update or not?

I don’t want to bother reading this much text explaining stuff, when it’s most likely nonsense

I’m not sure what you mean by this. There’s no further update to MANPADS currently since this was announced.

This is the current state of the game.

Mistral, Stinger and the HN-6 manpad missiles are nerfed because Gaijin believes that like 6-10 sources (flight manuals, marketing materials and technical documents) of the missiles themselves are inaccurate and since the Igla can’t pull more than ~10G continuous, Stingers and the other certainly cannot do that.

The gist here is that despite nomerous primary sources stating otherwise, Gaijin thinks that their crooked math and “we believe” is more accurate.

I just saw the date of the thread, thought before that this is some kind of update where they improved the missiles, but not anywhere close to reality.

So, being annoyed is what I should be.

Literally blatant Russian bias but let’s keep denying it guys.

Could someone further along in their (aerospace) engineering degree/career than me (who also isn’t as tired as I am rn) check out the following sources to see if they could help establish a better set of equations of motion to evaluate rolling-body missiles? If a set of equations was established, we could actually prove the overloads of the Stinger or Mistral.

The overloads have been proven, both by missile related documents aswell as flight manuals listing them at 16-18Gs for the stinger (this is for evasion proposes).

Gaijin has literally said that they themselves are going contradictory to multiple sources because they “believe” (meaning here: did enough miscalculations and dishonest assumptions until it fits their narratives) that because the Igla can only do 10G continuous, the other missiles should be the same because their control surfaces are roughly the same size.

This completely ignores the differences guidance algorithms (bang-bang vs.PID) and the rotation speeds aswell as all other stuff the western engineers did to the westerns weapon systems.

I know they’re using the wrong math, but with a new set of equations we would be able to say what the peak and average overload of a PID-controlled missile is

There is no need to, as the sources provide them: 16-18Gs.

But Gaijin doesn’t believe it because “math,” so try at least try to get something done we should prove how more efficient PID is.

Waste of time, gaijin’ll ignore it like they have with the Challies

Potentially, tbh.

Thought I’d throw these links out there.

Do you have a page showing the second and fourth source are unclassified and approved for public release? It only says unclassified

ADA397650 is listed as unclassified on the coverage.

20030071145 is a research paper, its citation can be found at; An Aerodynamic Analysis of a Spinning Missile with Dithering Canards - NASA Technical Reports Server (NTRS) and is listed as public

ADA073456 is listed on the top right of PDF Page #1 (microfilm overview, and again on the reproduced coverpage of the document PDF page #3)

19710065199 is unclassified as per the downgrade markings on the coverpage

and ADA466818 is listed as Class A(distribution unlimited); on PDF page #2 (Its documentation page)

Since the second source was AIAA I suspected it was fine, but wasn’t sure. The fourth source just says unclassified, though, and not unclassified and approved for public release (not trying to be an ass, it could be export restricted for whatever reason).

My brother in christ citation 4 is in a public library that is accessible online.

It didn’t say it explicitly, though. I assumed it was a military-personnel-only library
