SU-27 and R-77

[pepin1234]

There's a graph somewhere showing R-77 range: 30KM.

 

I will say you the same that say GGTharos. "The range is relative" . Also this expretion seem have any relation with the AIM-120 inside our game. I have saw the Aim-120 in pursuit, keeping the high Speed longly. I dont believe that. Nobody can affirm here the really range of the Aim-120, but suddenly the R-27 and R-77 is not more in secret and they have 40 and 30 km both.

 

and you can see the AMRAAM going twice that, twice to triple the range of a 77 for R-27ER (depending on the sources).

 

Not anymore. Now we have a pretty surprise with the russian missiles inside our game encyclopedia. Only Mach 3 for all the BVR russians Missile, that why they lose the energy so fast. Why?? is the new marketing filosofy?

They lose energy faster because they fly a non-lofted trajectory.

Currently gravity and launcher speed add to the missiles speed potential. there is no cap. having said this missiles are unfinished in their current state (making them look like broken ingame), there's lots of work to be done.

So maybe this theory is only for the USA Missiles. I often try to fire at 11000 m the R-27ER against a heading 2000 m target and is no way to get more range than the magic and unrealistic 50 km.

 

But if you like see how happy are the People with all that, just take a FC3 statistic and see how many thread about the R-27 and R-77 exist and how many thread about the AIm-120 exist.

Nobody is saying theres nothing wrong with R-27 flight modeling, on the other hand 99% of people fly low while shooting. Flying low costs, BIG time. When they fix it, flying low will still yeld lower ranges than those flying high.

That's a realistic range. The only way to get the absolute maximum range is to attack a high altitude, high speed fighter that does not maneuver. I don't see what 'theory' you are talking about.

 

The physics of this have fairly well understood results, which function as in reality: The guy firing his R-27ER from 2000m at you, who are at 11000m, will have a shorter range than you will firing from 11000m to 2000m.

Problems with missiles are being addressed.

1.2.5 patch is up go get it and see if theres a difference. :)

Sources? (except ER)

This is exactly the case. More often than not a Su-27 pilot is either lower, slower, or both than the F-15 they are fighting against. Then they'll launch from what I assume is Rmax (20nm from me) and wonder why the F-15 pilot feels largely un-threatened.

Got some graphs although some describe missile performance in different terms than others. The other sources are the available literature. But in this case you must choose the authors carefully off from the sensationalist ones.

 

There was also a video in the internet showing the DLZ of an AIM-120B (I think it was B) and has since been removed.

 

EDIT: these graphs are from left to right:

 

1 AMRAAM (not sure which version),

2 R-27ER,

3 R-27R export model (I think, someone confirm),

4 and lastly RVV-AE.

First graph - in Russian. From Russia with lo.. sorry AMRAAM :) It's not a serious and poor quality to understand the details of firing exercise. What the source of this? Version of AMRAAM? Fighter and target speed?

Graphs 2-3 - that's true, from operational manuals. And similar for R-73 is there.

Graph 4 - from West with ... RVV. Ops again :)

[Pilotasso]

I obtained these here but have forgotten exactly where they came from, so hopefully someone steps up to back those up. I believe the RVV-AE one is not western, probably from the manufacturer site.
