Has anyone figures wrt the costs of GaN vs GaA? Or what’s the base for these claims?
AFAIK by 2009 the equivalent GaAn MMIC (built by Creed) would cost more than X3 the GaAs article (if i am not mistaken built by the same company (or by Triquint?), i´ve saw the numbers in a brochure/pdf, and had some comparisons with GAN/GaAs aplications, but that was in 2009). With the technology going by leaps and bounds its probable that the costs have gone down (i dont have a clue how they are today).
This article his worth reading: http://www.mpdigest.com/issue/Articles/2010/sept/Opinion/Default.asp
Gan economics aren`t where GaA economics are currently, or in the immediate future.
Offering a GaN antennae for MMRCA would be more expensive, when price is the sole determinant at this point.
I don`t doubt that Captor-E will get GaN modules (or something better) at some point, but I doubt it is what India is being offered.
I would be astounded that Selex/Euroradar had offered a GaN based dish for the MMRCA competition.
I think its safe to assume that we are going to see a GaAs antenna in operational Typhoons around 2015 IF an external order is found or (bloody big IF) the four partners stop dillydaling about the issue.
One should not forget that the aerodynamically superior Rafale will get 90kn engines in the future. While Typhoon – well maybe somebody will buy Tranche 3B.
1º No one has contracted the 90kn M88 and unless some external client is found, dont hold your breath for the Adla or the MN to buy it.
2º The original RR XG40 went has far has 100KN, that was in 1985… If someone wants an EJ200 with more thrust (and if there´s one particular fighter in the world that doesnt need more thrust, thats probably the Typhoon), the Industry will be more than happy to deliver it
Yeah, no wonder Germany made it to Paris in a matter of weeks… 😀
Oooops, I’ll get my coat…
Just before I go; Sorry, couldn’t resist. *shuts door behind me* 😀
Cheap shot :p
And given Solenzara is in France, the french are the worst of the bunch :diablo:
Nic
😀
Well, to be honest, they are dam good hosts, every time that i´ve been to France, i had a very nice time of it.
Cheers
According to Eurofighter the TVN comes with the Typhoon 2020 variant proposed to the likes of Turkey, Qatar, UAE and Oman amonst other potential buyers. A couple of reliable sources reckon Oman could be the first user of the 2020 variant, maybe indicating that they’re due to sign a contract for a number of Typhoons.
I imagine the work going on with the TVN is pretty much done, its been in development since 1995-6 so now its just a matter of doing some ‘very minor airframe modifications’ and fitting ‘one’ to an aircraft & performing some flight tests, I believe. I say ‘one’ because Eurofighter stated that when the time comes to test the TVN they’ll initially fit one, then two.
Correct me if I’m wrong, but Eurofighter also stated that the TVNs can be fitted to a Typhoon “without” any airframe modifications, did they not?
Looking at this picture below I’m not so sure; if you take a look at the area just under the rudder, there looks to be a bit of airframe to take away so the TVNs will have room to maneuver:
Then again maybe the airframe will not need any modifications, if you take a look at the diameter of the TVN it is smaller than the fixed nozzle already fitted to the EJ200, leaving plenty of room for the nozzle to maneuver. So maybe no airframe modifications needed? What do you think?

The problem is not the airframe, its the FCS. They have to re-write a great big chunk of it.
Cheers
Does anybody know if they are going to be 2D or 3D nozzle? if there 3D would they not be able to upwards and outward to avoid the said part of the rudder and have the same effect ?

It was an AVEN design (thats a 3D design), but dont hold your breath, the tests were terminated by the end of 1998.
In France people are friendly to guests, so they let EF have the 2 fights. In real simulations and exercises Rafale dominates though.
Then the Spanish are awfull guests, and the Germans are positively horrendous. 😀
i don’t want to bang on about this, but it goes against everything i have come to understand….
and any other evidence? is this just a poke at one of the MMRCA candidates?
DACT at very short range versus an aircraft equiped with the JHCMS, it could be very well true.
First a few quick corrections to some mis-conceptions here.
– Having said that, it really does just come down to money. If a country has enough money to spend developing these systems, they’ll develop the technology. It really becomes a cost vs capability mentality. In terms of aircraft that weren’t designed for stealth from the ground up, BAe claims the stealthiest is the F/A-18E/F. The Eurofighter and Rafale did have some stealth technology applied to them, especially from the front aspect, to reduce their signatures. In fact, IIRC, that was why the Eurofighter went from the original rectilinear inlet design to the slightly curved variation on the production model.
– It should also be noted, that in terms of capability, the U.K. was looking at buying a squadron or two of F-22’s, even while buying the Typhoon, but they realized they simply couldn’t afford them.
A few quick corrections:
1º “In terms of aircraft that weren’t designed for stealth from the ground up, BAe claims the stealthiest is the F/A-18E/F”
– AFAIK BAE never claimed such a thing. They´ve claimed a bucket load of times in the last 15 years that the plane that was the “stealthiest” bar the Raptor is the Typhoon.
I think that you are mixing a quote by Bill Sweetman on Ares a few years ago from EADS engineers, and they never claimed such a thing, they compared the SH with the F117, not the others 4,5G´s.
2º “It should also be noted, that in terms of capability, the U.K. was looking at buying a squadron or two of F-22’s, even while buying the Typhoon, but they realized they simply couldn’t afford them.”
– How was the saying? “The boot was on the other foot”?
UK PLC never seriously considered buying a “couple of sqn´s of Raptor´s” despite being offered to them by the Clinton Administration, that and a Carlo Koop paper from two years ago that proposed that the RAF should ditch the Phoon and buy the F-22 (before that there was an identical paper for the US Marine Corps!).
Cheers
It’s not supposed to be about Rafale, Typhoon and Concorde. We all know that even though Rafale and Typhoon are better A2A and A2G platforms, they are rubbish at supercruise compared to Concorde. Did the Atlantic without drop tanks, too!
It was a “tongue in cheek” comment…
If you look in this forum you´ll find identical topics right from the beggining of the “Key Publishing Ltd Aviation Forums”, grand part of those ended up in “flames”. The “Rafhoon” debate has already been discussed “ad nauseum”.
Wich one is the better? They are two very similar products, designed with slightly diferent specifications, using identical technology and processes, one of them (the RAFALE) is a more mature platform.
In the end the greatest lesson that the European aerospace industry, MOD´s and governments should have learned was that its imbelivably stupid to waste precious few R&D resources in 2,5 identical designs (the 0,5 is a swede one :D). That lesson wasnt learned and we are seing multiple UAV´s/UCAV´s programs across Europe that heavily overlap between them.
My own personal favorite European Delta Canard? I am one of the very few who thinks that the non-french one is actualy a very beatiful aircraft, but my favorite never reached production, albeit it made a stunning display in Le bourget… in 1987.
Cheers
Sintra :
Certainly not Sintra .
Think about new sensor integration then sensor fusion integration and then , the learning curve with the new sensors and what new techniques could be employed to fully use the aircraft .
No joike here .
It took the AdlA and the MN 3 years to built the whole picture in AtoA provided by the Pesa RBE2 compared to the RDY . They are still finding new ways TODAY to use the radar , 9 years later . Same with Spectra , which has been updated 4 times since 1999 . At each step , it takes a couple of years to really understand what can be done operationaly .
As an example , it would take the Typhoon at least 3 years to integrate something like the A2SM , including the fusion with the radar , the FCS and the most wanted interaction with Praetorian .On the other hand , it is NOT gonna take long for the Brimstone integration on the Rafale because the onboard sensor’ s fusion is already there . The French will only learn how to use the weapon , which can also take 2 to 3 years in itself .
You ‘ll see that when the Typhoon will get its AESA radar , it ‘s gonna take 3 to 5 years to fully operate the stuff , trust me .
So , when I say that the Typhoon is at least 5 years behind the Rafale , you understand that I am NOT only talking about technology but about overall capabilities .
The 2018 Rafale will still be superior to the 2018 Typhoon . In fact , after 2018 , I see the Rafale getting an even bigger lead on the Eurofighter .
Just the fact that an AESA conformal array on the Typhoon is near to impossible unless to review some parts of the airframe like the nose , and to add larger LRXs which lead to a new re-design of the wings .
Same with a possible Aesa jamming array “a la Rafale” , no room enough .
Then , there is still the RCS difference …Cheers .
You are trying to prove something while you are completely ignorant on the “other side” develompment, capabilities or possibilities.
Your entire assesment is based on “faith”, you dont have any evidence, but you “believe”, its identical to the type of discussion used on football forúns.
Its still, well sorry, ridiculous.
My,my…
How silly, we all know that the Concord was suply superior to these two…
Presently , the Rafale is fully “omnirole” with an alreary founded futur way beyond the RBE2-AA capability while the Typhoon is at least 5 years behind in overall capabilities in every Ops you can think of , including the AtoA warfare .
.
Thats ridiculous
again try to dive bomb somthing with internal bay door.
There were multiple dive bombers who used internal bomb bays.
The likes of the JU88, the SAAB B17, SAAB B18, Curtiss SB2C Helldiver, Asahi D4Y1 Model 11 Suisei, etc, etc, etc, were dive bombers with their main bomb load placed in a internal bay.
