Default A-A Missile Effects Update

Hi guys just a little request for an update to add some diversity to the missile effects.

I think the new effects suit SAMS and Russian missiles but not so much for western missiles.

I know lighting conditions and exposure probably change what we are seeing but the difference is still apparent, so should we bring back the diamonds for the western missiles and maybe missile add contrails depending on altitude?

What do think?

Planes cause contrails because they heat up a large amount of air, expending it to create its trust, which then gets cooled down quickly. I'm not sure a missile would cause contrails as they do not directly heat up air to get their propulsion, instead they use a reaction which yields heat. I would tend to think that this might not be enough to create a drastic temperature change on enough air molecules to end up in a contrail. Also, the hypersonic speed of missiles would mean that there are more air molecules to heat in a given amount of time, making conning harder?

This is just an educated guess, hope someone has a real answer to this

Seems good enough to me, the contrail needs some time to form so the missile flies x distance ahead of it.
Maybe that's the reason you don't see it as much in the picture?

Also, over the years many variants of the aim-120 were developped, and i believe the newer versions produce less smoke while the rocket motor is burning.

Yes I agree the smoke trails do look good but I think there could be more flame variation depending on the missile.

Watch some more AIM120 or AGM88 launches and you will notice the pronounced diamond effect that's currently missing.

Its hard to compare videos or photos because there are so many unknowns (conditions, variant, etc) but I think we can all see that the current effects in game don't look as life like as they could.





Again just a suggestion and maybe its on the way already with new Edge effects.

I agree with the OP.

+1 I think, and I know it's work, to have an effect that best suites ordnance in terms of realism - that's what DCS is all about right?

Heating, expanding, etc. doesn't change a thing as long as the absolute moisture stays the same. In such conditions, you either need to cool the air or compress it or both to get below the dew point. Since burning hydrocarbons yields a lot of water though, the moisture content is changed, which condensates when the exhaust stream cools down to ambient temperature. Depending on the fuel used, the same can *potentially* happen in a rocket exhaust. A2A rockets use rather specialised fuels though. I don't think the exhaust contains much water vapor if any.

A lot of missiles/rockets need their own smoke set, its a bit of a mess last time I checked with S24/S5/S8/S25 all leaving identical smoke trails. Only S25L had its own much fatter smoketrail for some reason.

Also Hydra's should not have the same smoketrails as the russian stuff, pretty obvious when comparing recent Russian rocket footage from Syria to any Hydra use.

The whole thing needs looking at really.

With our lovely new vapour effects on the Hornet are we going to see any update to the missile flames?

That AIM-9X flame looks like its going to the moon.
