I’ve already explained this a million times for pro-russians players that pull out youtube videos of NATO missile launches to “prove” they arent low smoke/smokeless.
AMBIANT TEMPERATURE AND HUMIDITY IMPACTS SMOKE PRODUCTION FROM MISSILES IRL
What you’re seeing in your videos is water vapour formation from the exhaust, NOT smoke as typically seen from less advanced propellants like those used by older missiles, or russian ones.
Well, it affects ALL MISSILE, not just for NATO. And if you already turn off the smokiness, then EVERYONE. 1.5 the conditions under which a NATO missile does not smoke is not a reason to make them smokeless
It should be if it can be expected to launch under said conditions, theoretically it wouldn’t be impossible to actually model how this changes since the chemistry is pretty well understood and Ambient air pressure and temperature is already modeled, the only thing missing for an accurate model is modeling humidity and the dew point of ambient air, which for simplification purposes could be generated from the existing temperature and pressure models.
You do understand that they probably use different propellants right? Do we even know if Russians use HTPB in place of CTPB or other solid fuels for their relevant missiles? Pretty sure its well understood that the relevant low smoke US motors all use HTPB based compositions.
The low aluminum (smoke) compositions ( historically they tended to be HTPB based) give up some portion of their performance (more modern compositions can recover some of the lost performance) in exchange adjusting the conditions under which the equilibrium reverses and so trends into preferring to produce 2Al3O (Aluminum (III) Oxide; a fine white powder) as a byproduct instead of Al2O (Aluminum (I) Oxide; a colorless gas), the problem was the the Carbon in CTPB compositions based fuels works as a catalyst that promotes the production of Al3O2.
The old video is most likely the first version of AMRAAM that smoked.What kind of fuel composition in Russian rockets should be studied patents may have something written there
Its probably just a bad day where the the ambient temperature and absolute humidity at the point of motor firing are sufficient to noticeably influence the equilibrium of the reaction(s) taking place.
The AMRAAM has two motors the The “High Performance Rocket Motor”
which uses a single, reduced-smoke HTPB propellant in a boost-sustain configuration.
and the “+5 Motor” Rocket motor which is an enhanced version with an additional 5 inches of propellant.
(It doesn’t specifically list a change in propellant composition) Though it requires the use of the Shortened Guidance section to maintain overall length of the missile, this came into effect with the introduction of the AIM-120C-5. The lengthened motor can be a useful distinguishing feature, for deducing if the missile is an Early -C or Late C/D variant.
Is there a discernable difference between the 120A and 120B? I remember there being a range difference, but it might’ve been something I made up in my own head, since if the 120B had a better seeker (and so can detect targets at further ranges), it would be able to be deadly at further ranges than the 120A.
120B is easier to make ( should be cheaper in repair cost)
This BBCRF guy loves to complain about anything Nato. Its kinda annoying
That signs of Russian main alright
The propellant composition of the AMRAAM is already well known because orbital ATK has made such info public. It’s how DCS got such accurate motor and thrust data for the AIM-120C-5. The study for the AIM-120A performance has estimates that were too high and had wrong data for booster.
We now also have good data for the AIM-120A/B thanks to the Korean study in my OP, which is what is used for in-game.
Also, all the nonsense off topic stuff about ‘russian mains’ can stop. BBCRF doesn’t even have top tier Russia air rn afaik. Y’all can DM about that stuff or I’ll need to get staff involved.
How is this off topic? Y’all crazy
Question about the aim120 What happens if it loses the target in the notch at say 7nm?
Does the missle search the potential flight path to the intercept point or does the seeker cone immediately jump to the intercept point?
I would presume it scans and tries different methods of acquiring the target
It should use iog too approach the calculated intercept Point and turn on the seaker wen in Range
Wonder if that’s is modeled
Other question if I use the aim120 in close range
Doas keeping a radar Lock with the main radar do anything or is it fire and forget only?
I believe this will guide one missile, if you drop the lock it will probably not support it with inertial information and it will just travel to last point of intercept. Not sure.
This is for in-game of course
that was not the question, the question was if the Aim120 already had a lock and then loses it. what happens then in detail?
120s should have smokeless engine. I saw i think one bug report on it with it being acknowledged. Did devs said anything else about it or we are going to have full on smoke parade with 120s even though we shouldn’t? 54C same deal.
Seems intentional for now
With the MP change, they should probs wait a bit for the community to acclimate to radar missile combat tbh, as much as i hate the fact they’ve been dragging their feat on the AIM-54C issue for so long. Granted, there isnt any indication gaijin is looking at ever fixing anything about the AIM-54C, so were still stuck with the idiocy that is the AIM-54A being a better missile than the C in-game in every way but inertial drift…
Just me or the AIM-120 loses it’s energy very fast
