Cornerspeed

[Hans_Dampf]

Hi,

I have tried to find some info about the cornerspeed of the M2K, but without results. Does anybody here know this?

Hi,

 

It's around 350kt.

[Hans_Dampf]

Thanks!

It seems like when you touch the stick the speed just drops like a rock.

Well thats Delta wing for you. You should really pay much more attention to AoA then speed

[atsmith6]

The Mirage makes speed control in the High G turn really easy:

 

1. Full afterburner

2. Pull until the velocity markers are level with your FPM.

 

Now you won't lose any speed. To slow down pull to place the velocity markers below the FPM, and to speed up relax to put the velocity markers above the FPM.

 

Simple

...And don't climb if in a dogfight.

... unless the other guy can't climb.

In a wheelchair you mean? :D

Interesting doc for turn performance At 15000 feet...

Have you got the same for different others altitudes ? ...

Is that chart sustained turn rates?

[myHelljumper]

The line with a "0" on it is the sustained turn rate.

[Azrayen]

Please note that this chart is an estimation from an outsider.

It does not originate from the manufacturer nor from a client air force.

 

So: good doc, to be taken with a pinch of salt ;)

 

Simple example: the internal fuel load is off by 200kg (2960 on the chart vs 3160 IRL).

If calculations/estimations were made with "wrong" data, the then results may be "off" too.

By how much? It's anyone's guess...

The person who posted the original link got it from the natops manual, from what I understand.

And no sorry, he only linked the chart for 15,000ft.

AFAIK Cornerspeed differs depending on the loadout and weight of the airframe (including the fuel). However there is a really easy way of finding it. Ill just post this great video by Ironhand that any simmer worth his salt needs to watch at least once:

 

 

It's filmed in the "old" Flanker, however the theory can be applied to any aircraft.

NATOPS manual are US Navy aircraft manuals.

 

The Falcon 4 Mirage 2000 manuals are called NATOPS too because the author uses the same layout for his manuals.

 

And the above chart doesn't come from Falcon 4 manual, but as Az said it's an estimation and it doesn't come from actual Mirage 2000 manual either.

However, even if it isn't "spot on", it gives a fair idea for our purpose :smilewink:

[Raven (Elysian Angel)]

Yup it basically confirms what was said earlier in this thread: that the corner speed is 350-ish knots :)

[=Thrust=]

At 15000 feet for a certain Weight for sure :pilotfly:

[Robin_Hood]

I think this is as good a place as any to put this. Here are some charts that I did for the DCS Mirage 2000C. It shows the maximum instantaneous and maximum sustained turn rates.

 

 

Please note: I only did one configuration ; I did 20kft but haven't made the full E-M chart yet, so attached is the turn rate only ; also these were made in march and therefore obsolete (I should do them all over again with the latest FM changes), but nevertheless I think they are a start.

 

 

Everything comes from in-flight testing.

 

 

Here we go, I hope you find it useful.

Wow, big work Robin_Hood, kudos.

 

For your "next round", I suggest you add the precise DCS version used (not just 1.5 / 2.0) as indeed FM changes do occur regularly.

FWIW, I wouldn't make another round just now, but would wait a bit further down the road.

Yes, indeed, these were not entirely finished and polished, but I plan to add the version used next time (indeed I did just that on a previous similar undertaking). I may make a quick test for ITR (which is much quicker to do) just to see if it has changed a lot in this regard (although I expect that STR has changed more), but I have halted the tests at the moment. I am waiting for the FM to stablilise a bit (last changelogs had FM changes), although I don't really expect the FM to stay the same after my next series of tests anyway (fine tuning a FM being a long process).
