My prediction

Only thing that’s concrete (statement from head of vympel themselves)

same article also states 2 - 3 times more range over standard rvv-ae but it doesn’t direct quote it like it does with that earlier statement.


same article is also the only source I’ve seen for izd 810 (r-37m replacement)

Thanks to both, I was taking the values from StatShark, I was convinced they were using the values from the datamine which makes me feel weird about how their missile calculator works, it seems that all of their fin AoA values are different from the datamine by a similar factor. Either way, 24 degrees is still too low compared to what the footage shows.

But are you still gonna make a report and if yes, what are the values you’ll ask for considering that anything above 25 degrees of AoA isn’t gonna change the close-range performance by much according to your own words?

Really it should be anything in the 30-35 degree mark. Past that the missile will start to tumble end over end in high g maneuver if the software lets it turn that hard anyway.

I think you’re confusing fin aoa and the missile itself aoa

no fin aoa afaik.

maybe, but in his own words anything above 25 isn’t gonna bring much, and AIM-120A is already in the files at close to 25, meaning that the conclusion is there shouldn’t be anything much to be expected from increased AoA.

It really depends. It would make more of a difference on the 120c-5/d for sure due to the clipped fins. but the aim120a/b would probably still turn better even if the aoa was changed.

Okay, so update. The spreadsheet is wrong, the value in the files is in radians. So yeah, the AIM-120s are currently limited to 15 degrees of fin AoA.

Ah, i figured something was up. Because ive heard the 15 degree mark used in reports before.

Yeah I was about to feel the report didn’t have much weight given my guesstimates, but the difference between 15 and 30 degrees is visually relevant compared to 24 and 30.

Well it effectively undoes the random arbitrary nerf Gaijin did to the aim120. So pre nerf aim120 sounds fantastic. Not great at hobs shots but you cant just out pull it at close range either.

Well the report is up here, you guys know what to do.

If anyone has anything of use to add or maybe a better method to estimate the angle than my clumsy work, feel free.

For reference, the frames I used from the public footage:

Thanks to @imissisopod for providing the other video which was a lot better to work with than the MQ-28 testing.

Now we wait…

I would be really really surprised if they accept it. These types of calculation and frame measuring and stuff are not acceptable according to what I’m familiar with. Even in your own report, you frame these measurements as estimated/calculated, which Gaijin does not accept because they only accept concrete numbers instead.

It really is the only chance to get the missile changed. Sadly, i agree with you though.

I mean yeah, it’s a shot in the dark, I knew it from the moment I started messing with the angles. But well, it’s pretty much the best source we have for the one issue that has crippled the 120s.
