About the late Rafale demos on airshows like on the link I posted , the Rafale pilot Mickael Brocard said that he was often on 10.5 Gs with peaks at 11 Gs (!) .
 
Example , last month in Dubai :
h*tp://www.dailymotion.com/video/xmkij4_le-rafale-en-demonstration-au-dubai-airshow_news?start=2#from=embed
 
Then , some are arguing about Rafale 's dogfighting capabilities  
I know that the F-16 Blk50/52/60 FCS software Cat I is limited to 9gs only with a possible override emergency . Can a Viper stay on override and full AB for 2 or 3 minutes just to try to keep up with a Rafale circling around ?
 
Cheers .

They never talk about fly-by-light but about FBW with fibre-optic transmission . I admit that it is a bit confusing
That's because you don't know anything about technology.  FBW just means the flight controls are not mechanically linked to the control surfaces, they send inputs to the flight control system which then commands actuators that move the control surfaces.  Nobody says "FBL" because that's stupid.  Fiber is just another way of moving data around.  It has the advantage of not being susceptible to EM interference, but it is fragile and more difficult to service than copper.
 
It is pretty obvious that you think because fiber optics are involved, somehow that makes it "faster" or "better".  People like you are why Monster Cable is still in business :)

As in here.
 
 
 
Using your own citation.
 
"CDVE (Electric Orders Of Flight)" i.e. Fly by WIRE.
 
"CDVE and concept CCV (Control Configurated Vehicle)" i.e relaxed stability control.
 
"The CDVE of the “2000” consists of four independent channels having each one its own electrical power."
 
About that fiber optic data transmission system, you prevaricator?
 
"With flight number 479 carried out on November 3, 1983 by Patrick Experton, an attempt is tried out of a a data transmission fiber-optic bus to increas4e the the data flow rate. The Mirage 2000-02 was entirely destroyed by fire, with the exception of the bailed out pilot, on May 9, 1984 to the south of the d' Istres base, following an engine failure during  flight number 513."
 
Fly by optical, huh? Any more half truths in your quiver of LIES, BW? 
 
Have a good day.

I would not be surprised if there was a shared fiber-optic bus in the computer network that governs the Rafale pilot management system. I would be VERY surprised if they tried a fiber optic cable harness from flight computer to actuator motors all over that bird. That would imply a degree of stupidity that not even Dassault is known for. Long TUBES bend and pinch under lateral acceleration forces, you know.

Wrt the Snecma M88-2 engines core temp , the correct number is indeed 1850 K/1577°C .
The "flamme temperature" inside the combustion chamber is 2500 K/2226°C (!)
h*tp://www.tpe-a380.webou.net/fichiers_telechargeables/dossier_motorisation_rafale.pdf
 
On the M88-3 , the core temp is said to be increased by around 5% (1950 K/1676°C)
Newest superalloys like the N18 which is supposed to be some kind of "aluminiure de nickel dopé au zirconium" (can 't translate that in english , sorry)

will bu use to  increase the temperature "barriere" to protect the turbine blades from the heat . There are also some tests running using ceramic micro-powder . There is actually a lot of people (within and outside) Snecma working on some superalloys and when one takes the time to dig a bit (French language needed) , very interesting stuff can be found who proves that the Snecma boys know what they are doing . I read that they found new materials to shield the heat from the combustion chamber to the main and secondary cooling systems and that in itself would greatly reduce the wear and tear on some parts and also reduce even more the IR signature  .
Some are very busy .
 
Cheers .

Phaid , you give me little credit .
 
""Nobody says "FBL" because that's stupid.""
 
This is exactly what I understood when reading some Dassault studies the last2 days . It is also the very reason why they don 't say fly-by-light but fly-by-wire with fibre-optic transmission . I can read French Phaid
 
Herald , the M2000-02 crashed because of an engine problem (you 've learned it from the link I gave you) and from nothing else .
No where it is said that the optical FCS was involved , you stupid basher .
You can 't even think for a minute than I am being honest and I try to share as much as I can , posting credible sources and good links . You are a bitter character , nothing more .
 
Cheers .

I 've just noticed that you are trying to fool people , or you don 't know how to use an online translator .
 
Wrt the M2000-2 , it is said :
""Au vol n° 479 effectué le 3 novembre 1983 par Patrick Experton, est expérimenté une transmission de données par fibre optique VERS les commandes de vol""
 
Do you know what "vers" means ? Do you know what "commandes de VOL" means ?
Yes Herald , FBY in 1983 , 28 years ago . I rest my case .
 
Cheers .

Continuing the proud tradition of flame-outs and crash shorts that plague Dassault aircraft. It still does NOT ADDRESS your LIE. I translated that test and I understand it to mean DATA bus, NOT fly by wire. Same for the Rafale article you cited.

Ok Herald , it is convenient to forget that fly-by-light was working 28 years ago on the M2000 so you switch target and go for the early M2000 engines . Sad clown ...
 
It is IMPOSSIBLE for you to aknowledge anything but I don 't care , I really don 't .
I will keep posting facts and you will keep responding with the usual biased BS . I don 't care , I don 't write my post for you but for all .
 
Cheers .
