Mirage 2000C Engine update presentation

Hello Mirage pilots, we are happy to present you the upcoming engine update for our M-2000C module. The team has been working on a new engine model that is more accurate to its real life counterpart and allows for better damage and failure simulation.

This update should release on the Open Beta later this month.

In this update presentation we will first introduce the reworked M53-P2 engine model and explain how it was created. We will then talk about the change it will bring to the module flight envelope and finish by presenting the other changes this update will bring.

M53-P2 Engine

Introduction

The Snecma M-53 is an afterburning turbofan engine developed for the Dassault Mirage 2000 fighter. The M53-P2 is an improvement to the initial M53-5 improving throttle response as well as dry and wet thrust.

The engine is controlled by a FADEC (full authority digital engine control) computer that translates the throttle movement into a linear and predictable engine response. The FADEC takes altitude, speed engine RPM and temperature into account to maintain optimal parameters inside the engine and ensure that maximum performance is obtained in every condition.

Engine modeling

The engine of the aircraft is based on a physical model that takes every engine design parameter into account. These parameters are determined using public literature, SME feedback and general knowledge of afterburning turbofan engines. Unobtainable parameters are deducted from industry standard or tuned to match known performance points of the aircraft.

The engine model takes all possible external parameters (altitude, speed, temperature, humidity, pressure) into account to deliver a very detailed and as accurate as possible simulation of the engine.

This model is bounded by the operational limits of the engine, namely over-speed, over-temp, flameout and wear. These limits are not “scripted”, they are probabilistic meaning that when a limit is exceeded, a failure will occur after a randomized amount of time. The farther from the limit, the sooner the failure, until it is virtually instantaneous.

Engine performance

The new engine maximum performance has not changed significantly with the update, but it will be more accurate in all regimes of flight and also have a more realistic behavior.

The most evident change is the engine RPM that now goes up to 103% instead of 100%. This is because the aircraft was originally equipped with the less powerful M53-5 engine which would go to 100%.
The biggest change in performance will come from external temperature where a 15°C increase will reduce the overall thrust by 5%.
The new engine will also have an improved throttle response delay: On the ground, the time from idle to max thrust dry is 5 sec compared to 8 sec for the old model.

Engine failure and damage

When exceeding a limit or by undergoing battle damage, the engine will now encounter better modeled failures. These failures range from engine wear reducing performance to catastrophic blade containment failure, destroying the aircraft, and transformation of the turbine into a modern art sculpture.

Emergency systems have also been improved with the addition of the emergency oil system, emergency fuel throttle, backup FADEC and afterburner cutoff. These function as they should to allow the pilot to save a damaged engine and return to base.

Aircraft performances

In-flight behavior

In order to accommodate the new engine, the aircraft flight model has been adjusted. The new flight model will keep most of the characteristics of the old one but with an adjusted drag for both speed and AoA, pushing it closer to known performance points.

The aircraft can now follow the standard break procedure, something that was not possible previously due to the drag being too high at high AoA.
The aircraft can also cruise at Mach 0.95+ at altitude with an air-to-air combat load.
The supersonic drag curve has also been adjusted, being the highest in transonic then reducing once out of this zone.

Ground behavior

We also took the time to adjust the behavior of the aircraft on the ground. The new suspension should better reflect the real aircraft like the bounciness of the front gear.

The aircraft will now roll on idle on even ground and no brakes are applied, check the wheel chock before starting !

New bombs

With the inclusion of the SAMP bombs into DCS, we added the SAMP-250 to the loadout of our Mirage. The SAMP-250 is a 250 kg general purpose bomb of french design that was used by the French Air Force before switching to the Mk-82 bomb.
2 versions are available, a low drag and a high drag version with a drag chute kit.
It is to note that the release profile for the low drag version has not been adjusted yet and that they will always fall long. We will work on fixing that in a future patch.

Other changes

In addition to the engine rework, we implemented a lot of quality of life updates for the Mirage.
We will list some of them :

• Added slats effect when deployed/retracted manually.
• Dissociated the 4 slats so they can be damaged independently and affect the FM.
• More realistic VTH field of view constraints.
• Added fuel dump trails.
• Improved exterior lights.
• Added customizable elastic limit (special options).
• Added “MISSION ACCOMPLIE” Mirage 2000C retirement celebration livery.
• Fixed green radio default preset to 01.

Updated manual

To go with the release of this update is the updated manual. The manual has been updated with the latest changes for the Mirage 2000C.

It will be available in your game files (DCS Word/Mods/aircraft/M-2000C/Doc) and can also be download here :

Conclusion

With this update we again pushed the Mirage systems realism where they deserves to be. We will continue to improve the aircraft remaining systems and work on more detailed failures and damages.

And to everyone flying the Mirage, thank you for your support !

Updated manual

 

Well. Are you planning to update the training missions? I would love to relearn her. I have stopped doing it last year after huge updates. I think now is the time to bring everything with her up to date.

Thanks. 

[Akiazusa]

wow  ,can't find a word to express my like and appreciation

So many things have been added to the Mirage this year.The details on it are already blowing my mind。

And thanks for the “MISSION ACCOMPLIE” livery，it's because of your hard work that we can still get this beautiful plane flying in our sim after its retirement.

Good job and keep going.

[de.Impact]

Setting new standards !

[Mr_sukebe]

Excellent news.  Took the current version out earlier this week for a spin around the SA map, lovin it.

[notproplayer3]

Simply excellent, the mirage trully became one of the best DCS modules because of the work you put into updating it and this engine update shows yet again your commitment to your product, thanks a lot for that !

On that note, are there any other major reworks that are planned for the M2000c or that you know you will end up doing down the line ?

[skywalker22]

Can`t wait to try it out indeed, amazing job guys.

If I'm reading that correctly, does that mean we'll be able to snap that nose around even faster now when dealing with those pesky F-18's?    Errr, I mean, so we can do a standard break pattern...

[Rudel_chw]

Wow .. the manual more than doubled in size, from 320 pages it went up to 689 ... thanks a lot Razbam and @baltic_dragon .. I just love extensive documentation  

[Krippz]

Great update boys!

[Bremspropeller]

Thanks a lot for your continued commitment to this moduel!

Can't wait to try out the new engine model and all the other tweaks.

Btw, perhaps replacing the PDF download with a direct file link, the preview link right now tries to open the PDF which at this huge size and complexity it'll probably never do in-browser, or it'll take a lot of RAM and lag a lot.

it is a direct link onto a google drive file .. perhaps you are using google chrome as a browser

It does look like one yeah but, it open a page with a loading icon that spins forever and there's a small icon in right upper corner for download.

It's Firefox for OpenSUSE (linux) Tumbleweed currently.

ADD: Same thing happens on a  much older Firefox on Windows 10

Strange .. the links works fine on my iPad and on my PC:

I haven't had any issue with it, inside Chrome, on several machines, or via straight download. The entire manual is only 25.6MB anyway, which of course, put in RAM terms is only 2.56% of 1 GB, that doesn't seem like a size that should be taxing for any reasonable system these days, when a bargain basement level PC (and I doubt anyone here has a basement level machine for DCS) comes with 4GB of RAM, and much more commonly, 8GB.

It also loaded fine on my phone, which is only a PIxel 4a, no monster by any means.

[QuiGon]

Great stuff! There's nothing that gives me more trust in a developer than kind of product comittment gives. Keep it up!

[bies]

Great work RAZBAM, i appreciate all this details.

Yeah false alarm, I was opening it in LibreOffice Draw which took 1.8GB RAM, I think because it loads the whole PDF as an editable document and fully caches it into RAM, not just quick view. Opening in Okular or Foxit PDF Viewer on Windows takes less than 100MB.

[Big-foot]

Thanks for the update Razbam! Looking forward to flying an even more realistic Mirage 2000. Incredible how such an old module has grown from an incomplete module to the best fighter jet simulation and keeps getting better!

[Leon.S]

Hey there,

Im new here with the mirage and was wondering if there was any chance of there being a m2000-5 variant in the future? I really like the mirage but i feel like the lack of A/A weapons really limit the jet in BVR fights such as against the F/A18, and the -5 variant would be able to carry 6 bvr fox 3 missiles and that would really make the mirage so much more competitive and a challenge against more modern jets. 

 

PS: I apologize if this has been asked before

AFAIK (via Discord) Razbam have no plans to model the M2000-5 in the near term,

... as to what might be available in the future, that will likely depend on AdA's requirements and how much (if any) they are willing to share publicly.

AFAIK there's not enough publicly available info on the 2000-5 to make a DCS level module without the help of the AdA.

Thanks RAZBAM for the good news and for your work on the manual MyHellJumper.

Will it be necessary to maintain full Mil Power above M1.4 (M1.6 ?) or will the FADEC do the job for us?

Will there still be some kind of engine compressor stall above lvl 655 ?

Thanks for the kind words.

The pilot needs to maintain MIL power avobe Mach 1.4 by himself, the FADEC won't do it.

I didn't test high altitude flameout of the engine, I'm not sure at what altitude it will happen.
