The "Silent Killer" Missile - MBDA MICA - Performance and Discussion Thread (WIP)

https://forum.warthunder.com/t/the-super-530d-should-be-fixed/26429

Both aircraft are at high altitude. ASRAAM is also Mach 4+ missile with a long burn time to. It produces barely any smoke in comparison to mica.

Nah, ASRAAM is M3+

MICA’s (potential) high speed likely comes from its loft profile, 6s burn at 750m/s is really not that crazy at all

range is approximately 60km, which makes sense if it lofts.

The ASRAAM is stated as MACH 3+ with a boost sustain motor.
The concentration of aluminum in the engine is the main factor in the smoke and stealth of a missile.
Reducing the aluminum content reduces the rocket motor’s ISP, and therefore its power and Delta-V.

As for powders, they haven’t changed significantly for almost 50 years. The addition of aluminum brought a little boost, but the dosage had to be drastically reduced (to around 2%) to reduce smoke and improve the radar discretion of combustion products.

MICA uses a low-aluminium HTPB composite powder to reduce its EM trace ans smoke.
But even with low smoke, you can see it at high altitude. But don’t forget that the missile only burn for 6 seconds so it’s quite hard to see it.

Even if on the video, the ASRAAM look like it got almost no smoke, it could depend on the camera, the luminosity, and other factor we don’t take into acount. So if they were shot side by side maybe we woulnd’t remark the smoke difference too mutch.

Even if the ASRAAM is low smoke , it’s still a missile optimised for long range so it need to have a punchy rocket motor. You need to have some Aluminium (and so smoke) to have a better Delta-V (as explained earlier).

Here on the VL-MICA video, you can still see smoke but it’s a lot less than on the video you showed.

The 750M/S is just a figure MBDA used for a presentation.
Since the VL-MICA ,which is ground launched, has a maximum speed of MACH 3, it means the Delta-V of the MICA is around MACH 3 or 1160M/S.

The MICA can loft like the ASRAAM.
You can see on the video Flamme posted that the ASRAAM go directly up. I don’t think it could obtain 50km range while being a only 88kg missile without lofting.

Depends if you’re talking about the MICA IR or the MICA EM.
The MICA EM has a stated max range of around 80km.
The MICA IR has a stated max range of around 60km.
The difference is due to a less aerodynamic seeker head on the MICA IR.

Does anyone know why the french uses sutch a long nozzle connecting the propelant grain/rocket motor to the exit cone?

For the SUPER 530D:

The Rocket motor is inside the red area:

Inside the interior of the rocket (all of the motor section):

The MICA share the same aerodynamical formula as well as the same motor shape.

For the MICA:

It look like the propelant grain is also far away from the exit cone witch means it also look like this:

Even the MICA NG has a long nozzle:

Even the MICA NG has a long nozzle:

You can see here that the MICA NG keep the long nozzle and instead of adding more propelant grain in the place of the nozzle, it add propelant grain in the previous space of electronics (thanks to reduced warhead and electronic size).

Why is the nozzle so long instead of using the space for more propelant grain and so more range?
The only think i can think about is center of mass but even then…

For comparaison:

AIM-9X

It simplifies the change in center of mass of the missile. For tail control missiles this is favorable as it improves stability pre / post burn. It also leaves additional room for larger or stronger control actuators at the rear.

You’ve compared it to the AMRAAM, which makes sense… but the remainder are canard control missiles with little need for room in the rear for a control actuator section. The reason the AMRAAM has such a design is that they want the missile to be less stable on launch than post-burn. This relaxed stability allows tighter turn radius and better initial bias turn or in some cases, off-boresight launch.

The high-angle off-boresight capability most likely was first introduced on the AIM-120C-5 since they were able to shorten the control actuator section (SCAS)… this allowed for a longer motor and further changed the CoG shift pre and post-burn.

Generally, the smaller the tail controlled missile… the more often you see this design feature.

Nonsense MICA small-radius rocket R-27ER medium

MICA 50-60km 27ER-130km

MICA is 60-80 lofted, R-27ER is literally double this under any conditions.

Complete nonsense
All the missiles are in approximately equal conditions

Wdym equal conditions. Unlike others, only one country has a proper dogfighting fox 3 missile

80 km for RF version, 60 for IR

And it doesn’t really matter much when one can go nose cold and the other can’t

Not like any shot is made at 80km either in the average Air RB match

you know, i’m starting to think they will add AIM120 and R77 while some will be stuck with S530Ds X)
Which by the way could explain all the buffs magic 2 and S530 got recently

if they make 530s not self explode and add dual plane for magics and fix irccm i think we can survive for a lil longer but still mirage will be a bottom feeder of air rb games just kissing the deck and killing everything low
