Russian MiG-31 shot down another Russian MiG-31. Unauthorised launch of R-33.

Flight time of the MiG-31 at supersonic cruising speed M = 2.35 fifteen minutes
By: stealthflanker - 8th February 2019 at 03:48
The real question is probably. “Can MiG-31 do a sustained cruise in supersonic speed with R-73 and R-77 ?”
AFAIK the old Bisnovat R-40 was designed with titanium airframe as it was meant to be carried externally and to withstand sustained thermal load when the carrier aircraft (MiG-31 or MiG-25) going supersonic and cruising at that condition. Missiles can go to mach 4 yes. But it’s for few to tens of seconds after launch. While the carrier aircraft may go supersonic and maintain it for minutes and might be in different altitude. This condition will weaken the missile airframe and roughly shortening its lifespan.

Nonetheless Before calling a shot on MiG’s because it using “non mach-3 carrie-able” AAM one have to consider that the threat requiring sustained high mach numbers no longer exist. The highest is probably Mach 1.5-2 and that for high altitude mission, maybe launching Kinzhal or that Big Kontakt ASAT missile. It can go Mach 2.8 or even 3, yes. But it’s not just that Merit Russia keeps the MiG.

The maximum target speed is 2500 km / h, which means that the speed of the P-73 is above this value.
Restrictions on the launch conditions of guided missiles (Su-27, points 5,6,7,8)
H = 15000 – 18000 m на V= 650 km/h (до M = 2,35) H < 15000 m на V= 300 – 1100 km/h (до M = 2,2)

R73 imposed speed restrictions are far below Mach 2.

No, the plane could probably reach more than 2.83 M if it REALLY had to (as MiG-25 could). But it is officially cleared for reaching that speed:

In that case, why does he need a steel structure?
The maximum speed of 3000 km / h, M = 2.83
Cruising speed is 2500 km / h, M = 2.35 (up to 15 minutes)
MiG-31 has less steel than MiG-25 – a lot more aluminium http://www.airbase.ru/sb/russia/miko…31/index-t.htm
I know the MiG-31 can reach mach 2.83 if it really had – but it is limited to mach 2.35 like a lot of other aircraft.

The MiG-31 is capable of developing a speed of 3000 km / h with four R-33 missiles, this is precisely known. I think that R-73 or R-77 under the wing will not prevent him from doing the same
I thought the MiG-31 was limited to mach 2.35?

Ok !

No problem

Paralay,
Is it M2 capable with all those ordnance ?
By: stealthflanker - 6th February 2019 at 14:58
Oh nice one there. Now we just need to wait for an image.
Same case as R-77-1
By: GromOzekA - 5th February 2019 at 20:47
R-37M missiles are clearly exists, because KTRV was paid to test it in late 2018. It was periodical tests. Such kind of tests generally happen to items that was produced some time ago and was in storage for a few years.

AFAIK there are not details revealed from R-77-1 with the MiG-31 , so it is not possible to say that the R-77-1 could have been fired with the MiG-31 above Mach 2 like the
No problem

In fact the Stealthflanker has been correct in all aspects in my opinion, just point out some details: all versions of MiG 31 (Dz / B / BS / BM / BSM) that had been come into operation with 04 semi-conformal compartments on the belly from MiG-31, all those compartments has been equipped with a hydraulic bracket called AKU- 410, which removes the R-33 SARH ( semi-Active Radar Homing) missiles from these compartments in order to release it for ignition of the propellant of these missiles.
The R-37M ARH(Active Radar Homing) missiles should have been compatible with the MiG-31 compartment as well as the AKU-410 system. Therefore, 04 R-37M could have been used by MiG-31 (Dz/B/ BS/BM/BSM).
While the MiG-31M prototypes were equipped with the AKU-610 system and 06 compartments on the belly, in which case the MiG-31M would have been capable of using up to 06 R-37M missiles.
In this way it would not be reasonable to perform such drastic modification in the internal configuration of the MiG-31BM / BSM in order to introduce two new compartments and the AKU-410 or AKU-610 device to increase the amount of R-37M missiles to 06 units.
However, there could be another possibility for the MiG-31BM / BSM, until 2009/2010 the MiG-31 had been used two heavy R-40 (AA-6) missiles on the internal wings supports, so an alternative could be use the R-37M in this position too.
Actually, there are none mention or even picture from R-33 missiles has been carried by the MiG-31s on these wing supports, but with the dissemination of MiG-31BM images has been using R-77-1 (RVV-SD) missiles, as well as in the past the MiG-31M with the R-77 (RVV-AE), this would be at least one possibility, since the R-77 missiles use the method of releasing and subsequent ignition of the propellant, in the same way as the R-33 and R-37M.
AFAIK there are not details revealed from R-77-1 with the MiG-31 , so it is not possible to say that the R-77-1 could have been fired with the MiG-31 above Mach 2 like the: R-33 , R-37, R-40 and Kh-58U(anti-radiation). Both R-40, Kh-58U (ASM), R-60 and R-74 are fired while on rails.
Today there are not evidence that RVV-BD (R-37M) has been in production or operation, but tomorrow this may change as the SAM BUK M3 with ARH (active radar homing) missiles are already in operation with the Russian Army . In the early 2000s such version of the SAM BUK M1/2 with ARH missiles had been offered with the radar seeker derivative from R-37M
Perhaps the most important point should be that the R-37M missiles could have been put into operation with the Su-35S and Su-30SM today, in addition with the MiG-31BM/BSM.

Four it is! Thanks!
By: stealthflanker - 5th February 2019 at 02:01
Yes 4 to make it 6 like MiG-31M many alterations have to be done including removing the gun. and please dont rush. This is a forum board not a real time msn chat.
