Read the title, BW.

Did you read this old pdf entirely ? 

I often use Mr Hironde studies , he is the Rafale Program Manager .

 

Cheers .
If you only knew why I KNOW this.

Herald , the link you just gave me has nothing to do with the thread at hand !?
 
What 's the Falcon people are doing here ??? Mr Hironded managed so many programs ....
 
Cheers .

Not my problem. All I have to do is let other people read it, BW. They'll figure it out quickly enough, and that is ALL I need to bury you, once and for all.

Nah, just empathetic ....

In all my entire doc on the Rafale , only one paper talk about 2100 C . All the others say 2100 K .
So , I guess it 's a typo error and I go for 2100 C . I will call a friend and try to know more .
 
In most cases the temperatures are given in kelvin not in degree celsius, though the later is possible as well.  Can you link to any credible source which states this? Thus far all information I have seen on it state 1850 K/1577°C!
 
Only the first prototypes used the FBW . The FBL has been tested later on on a M2000 and implemented on the serie Rafales under the name CDVO (Commandes De Vol Optiques) .
h*tp://www.flightglobal.com/pdfarchive/view/1986/1986%20-%200009.html
h*tp://www.armees.com/le-dassault-rafale,34602.html?artpage=3-5
h*tp://fr.wikipedia.org/wiki/Dassault_Rafale
 
The flightglobal article doesn't mention FBL at all, it's talking about FBW! The other two sources both state the same, so one is a copy paste of the other. No sources are cited and this claim makes no sense at all!
"Le Rafale dispose d’un système de commandes de vol électriques en fibre optique"
 
You either have an electrical or an optical system! Any credible sources for this from Dassault?

The Flight Global article does mention FBL in the last paragraph on page 9:
"At present, the Rafale has an electronically signaled fly-by-wire system, but the ACT/ACM will use fiber optics for data transmission; a fly-by-light system is currently being flown in a Mirage 2000"
 
Given that the 23 year old article was talking about different ACT/ACM variants and everything currently published just refers to FBW, I would guess that FBL was abandoned when it came time to focus money on aircraft development.
 
On the other hand, the F-16blk60 has a fiber optic electronics data bus
'New avionics for the block 60 includes a higher-speed mission computer, a new display processor, three large colour LCD displays, advanced data transfer unit with a fibre-optic data transfer network."

It's fly-by-pulley, using the latest in hemp cordage and the finest teak and mahogany housing....

I 'm coming late from work .
I phoned Dassault but I've been told that the people were gone home . I 'll try again on Monday .
 
So for now , let 's say that the Rafale is using a fly-by-wire system (until Monday) .
Nevertheless , few interesting things to note :
 
- as Breaka said , a M2000 has been flying with a fly-by-light system . It was the prototype M2000-02 who flew first with the system on November the 3rd , 1983 ,on flight No 479 . That was 28 years ago
h*tp://armeesfrancaise.chez.com/armee_de_air/mirage/mirage.html
 
- lately Yannick Barthe , a French professional in aviation , had an interview with one of the Rafale demo pilot , Mickael Brocard , he had the confirmation that the Rafale is using a fly-by-light system it seems :
""Commandes de vol électriques en fibre optique""
Note the aircraft price : 142 300 000 € (?)
h*tp://www.startin-sport.com/avion-de-chasse-rafale-camera-embarquee.htm
 
Since we 're on fibre-optic , Breaka said about the F-16 Blk60 :
""advanced data transfer unit with a fibre-optic data transfer network""
 
Rafale has it from day one .
The first Rafale A prototype (demonstrator F-ZJRE) was already equipped with fire-optic data transfer network :
""transmission des ordres par fibres optiques""
h*tp://www.museeairespace.fr/votre-visite/collections/prototypes/dassault-prototype-rafale-a-f-zwre/presentation.html
 
The Rafale A is also known to have used a fly-by-light system .
I also know that the Fly-by-light developement cost is 30 millions Euros . 
To be honest , it wouldn 't surprise me if I got the PERSONAL confirmation on Monday that the Rafale is using Fly-by-light . For the last 2 days , I read tons of pdf from Dassault and something is curious . They never talk about fly-by-light but about FBW with fibre-optic transmission . I admit that it is a bit confusing ...
Since the Rafale is already equipped with a fibre-optic network and since it is nuclear capable and since every kilo is important and since fibre-optic is not that expensive , well ...
 
Cheers .
