Ракеты в DCS

[Selliese]

Текущая AIM-7E2 должна не превосходить AIM-7F в скорости на ближних дистанциях?

do you have any want of the SMT pilots handbook for the Zhuk radar? It’s for the Yemeni version with lacks a hump and is otherwise very similar to 9.12

А когда ракеты с икгсн смогут захватывать нагретые наземные цели, вроде бы обещали

Why is R-77 the only active missile in DCS that causes a launch warning from the fighter aircraft when fired from STT?

Aim-120 and SD-10 do not give a launch warning from the fighter aircraft in STT, only when the missile itself goes active the target receives a warning from the missile.

There is no dedicated CW illumination signal from the fighter radar when the missile is launched as it would be with an R-27R/ER. Only some missile datalink that is probably much less obvious. It does not make sense to have the fighter aircraft give launch warning when firing R-77 but not when Aim-120 or SD-10 are fired.

Because the old radar MiG-29S switches to special continuous target tracking mode at launch.

This happens exclusive only on R-27R launch, not on other missiles. Are we sure that it would be forced ON on R-77 launch?

Let's go from the other side. Are you sure it doesn't turn on when the R-77 launch?

[BlackPixxel]

R-77 is a totally different missile than R-27R/ER, why would the radar switch to a mode that is made specifically for R-27R/ER when firing R-77?

On top of that, with R-77 4 different targets can be engaged at the same time (With the PESA radars for example). R-27R/ER datalink only allows for up to two targets, there is no bit left in its datalink structure to allow for a third and fourth target. So it can not rely on the old datalink commands from the R-27R/ER

As well what Blackpixxel said, the R-27R waveform is known as has its limitations, if used for R-77 it would mean that you can just slap on R-77 on any 9.12 and it would function, which we know it is not the case.

Address these questions to the MiG-29S developers with old soviet N011 radar

To use a missile, it is not enough to have a suitable radar radiation structure. It is necessary for the weapon system to be able to work with the missile, self-test, INS alignment, data transfer, WEZ calculation and other procedures.

Yes, which leads that if they changed all that, why keep the launch procedure exactly the same?

And lets assume they did... it would mean they are not able to send DL to the missile flying to the 2nd target which we know S is capable of doing, due to the specifics of the R-27R datalink and STT.

That would in turn mean they are using other ways of sending the datalink to the 2nd target missile, then again why turn-on the R-27R CW since we know it is not turned on launch of any other missile, so it is not a must. 

All in all, if the same procedure was used as for R-27R, two target firing wouldn't be possible. 

I know that due to current DCS module composition R-77 isn't a priority missile or in any focus, but please reconsider this since it feels like a needless carry over from the past.

There are speculations, and there are facts. Before do anything, we need to know these facts. We will try to find information.

The National Air an Space Museum has some documentation on the Mig-29SE, possibly marketing information or something from an export customer, Like Peru or Malaysia.

anyone in the DC, mother Virginia area able to take a look?

the documents are

It would surely be nice if our MiG-29S had N011 radar

[BlackPixxel]

Something can in no way be right with R-77 when a loadout of just 6x R-77 is nearly as slow as a loadout of 6x R-27R + 4x R-73 in acceleration:

I spawned at 8000 m with 50% fuel, enabled autpilot and went full afterburner.

The 6x R-27R + 4x R-73 loadout is 908 Kg heavier than the 6x R-77 loadout, almost a ton! And so much more drag is there from the many missiles and pylons. Yet the acceleration is almost the same as just 6x R-77. It shows that R-77 on pylons have just way to much drag in DCS.

A pure 6x R-27R loadout is zooming away from a 6x R-77 loadout.

My mistype. Of course it has the N019

[BlackPixxel]

Why does the R-77 in DCS have such a bad ballistic coefficient along the whole mach range, when for supersonic speeds the grid fins are fine?

 

null

[Chizh]

What is ballistic coefficient?
