I think there was an aerodynamics issue with a canard delta with canted twin fins. I recall reading about that issue a while back. The CGs therefore look unrealistic to me. I’m still holding out for a more conventional design.
I’ve heard the same thing. I think it had something to do with interaction between canard vortices and canted fins. I can’t remember where I heard that. My aerodynamics studies were mainly limited to playing with lift/drag curves and potential flow theory in my Aero I class in my college days (us space types only had to take 1 semester of aero classes but I digress). So I could be wrong about the vortex interaction explanation. Anyways the MiG 1.44 apparently had no issue with this- it was considered aerodynamically quite excellent by its developers as I recall hearing. The Typhoon also tested a twin tail configuration in some early wind tunnel tests but they went with a single tail.
uh you do realize that was the Lockheed model right? and in the end, they chose a conventional layout for their F-35. wonder why.
I believe they chose it because the canard+delta would have been too high risk development-wise (or safety-wise?) if used in conjunction with the lift fan.
You’re thinking of the NGJ stand off jammer, not the ASPJ from BAE.
I’m not sure one can use the lack of negative press as evidence to support an alleged shortcoming. Additionally, the F-35 will already be cruising at a higher speed, and unencumbered with external stores, so the likelihood that a combat loaded F-16 will out accelerate an F-35 is minimal.
The EODAS will still provide marked advantages in the WVR realm.
Is the ASPJ fitted to the F-35? Is it carried internally or externally?
I wonder if they could use the WS-15 core with a modified WS-10 Fan+LPT? I guess they would have to add a TVC nozzle as well.
Well here it is at last – I hope – of the long awaited stealth fighter from China’s Chengdu (611) is already reported to have flown for the first time on December 5, 2010. I make no claims here people, just reporting. Those that are interested should watch the video on You Tube
Thanks for the wonderful cgi.

I thought the CVF’s will be going the CTOL route now that the UK has decided to purchase the F-35C rather than the B? If the F-35B and C(?) did get cancelled, so I suppose they could buy Rafales or Sea Gripens. But I do not think the F-35C will be cancelled… The F-35B on the other hand may…
U.S. may eventually export the F-22, it won’t be for at least a few years. Should we suddenly shift our stance and sell the F-22, I’m sure we’re going to anger a lot of JSF partners particularly the UK and it would hurt our own sales of the F-35 driving up the production cost.
Unlikely- I think the production line is either closed entirely or that significant parts of it are closed. It would be quite difficult to start it again.
How is it possible that the Rafale with advanced spectra active cancellation stealth
can be defeated by a lowly last gen block 50 F-16s?
AWACS, assuming it even happened at all. Now stop trolling.
Yes, I suppose the apg-77 might be a bit more difficult 🙂 Now at last, we are getting to the juicy stuff! Any source on this exceptional ability of the Spectra – Kovy, Arthuro, Nic, Tay, Blue, Tmor (or his ghost), anyone?
Also, this Mach 1.2 supercruise is confirmed then? When, where and what kind of load out if you will,please.
USS.
Right from the horse’s mouth:
http://www.thalesgroup.com/Portfolio/Defence/Aerospace_Product_SPECTRA/?pid=1568
Using sophisticated techniques, such as interferometry for high precision DOA and passive ranging, digital frequency memory for signal coherency and active phased-array transmitters for maximum effectiveness and covertness, the highly advanced multi-sensors and artificial intelligence data fusion capabilities of SPECTRA provide the Rafale aircraft with the best chance to survive in harsh and lethal environments.
is it true that Rafales lost to block 52 F-16s?
Given that they had AWACS support, then that’s hardly surprising. Then again, you should probably always assume the opposite of whatever you read on StrategyPage.
This is a problem only IF significant problems are identified in testing. So far that is NOT the case, nor is their cause for concern other than the utterly stupid series of “what ifs” detractors like to point in their direction of choice…
The bulk head issue everyone is so “excited” about is a durability test bulkhead 1500hrs into testing that has been discovered with a crack. Not a failure. A crack.
No-one has identified HOW this crack occurred (component failure, test rig failure, initial manufacturing failure are ALL distinct possibilities) and enquiries are underway to determine it.
No other significant issues have occurred. Minor component failure has occurred, true. L-M hasn’t shied away from admitting these things. Personally I can’t wait for 5 years down the track. If F-35 sails through flight testing with only minimal issues, will you all be big enough to admit you were wrong or simply change tack and criticise from a new direction?
I’m pretty sure that a crack signifies a failure of the test. It is not a catastrophic failure where things blow up in spectacular fashion, but it is likely a failure to meet a critical technical parameter by a large margin.
I’m not suggesting that flying with a sustained 60 degrees attitude is an advantage. I’m saying that the F-22 has tremendous nose pointing authority, while remaining under carefree control.
Very true. TVC does provide some nice advantages when it comes to noise pointing. IMHO, this is somewhat offset by HMS+HOBS missiles, but there is no guarantee that an aircraft will not have run out of missiles.
A Rafale sustained >60 deg? It’s not a matter of how many degrees you can reach instantaneously.
I realize the F-22’s top speed isn’t that relevant, but it does have a sizeable supercruise advantage, speedwise.
I think that if you sustain 60 AoA then you’re simply just gonna bleed speed. It might be useful in a guns only turning match, but even then your going to have sinking problems. I’m afraid I don’t see why you would ever want to do this. I’d rather have a greater turn rate than an amazing AoA.
you lost me here.
1. The Rafales radar isn’t even as good as a Block 60 F-16s let alone a raptors its isn’t a full AESA and the raf will need power upgrades in order to receive so standard block 60 capabilities.
2. I read where the french said the F-22s used used there radar beacons for WVR ( luneberg lens). THIS makes sense, its the only way they can get to the merge with the Raptor and make it a fair contest.
3. The reason that the kill ratio wasn’t higher was because of fuel consumption.
I suppose super cruise and TV burns alot of gas.
You won’t be supercruising in a WVR fight.
The F-22 can passively engage a target using either LPI aesa or the ALQ-94
About the effective detection range of AN/APG-77 according to AW&ST:
AW&ST 2000/03/17, 120 mile (192 km) at “Stealthy mode”.
AW&ST 2000/03/17, 140 to 145 mile (260 to 270 km) at “Non-stealthy mode”.
AW&ST 2000/03/17, radar image with 30 cm-class resolution for the target 100 miles (160 km) away.
AW&ST 2000/03/17, TWS 100 targets at the same time.According to the reports of Mr.Billsweetman a few years ago, F/A-22 can detect the target of 400~460 km away with the help of ALQ-94 EWs. And the effective detection range of AN/APG-77 is about 185~230 km, which has some sacrifice because of energy / emission controlling for stealthy issue.

Its hard to verify the the article since I beleive it was in print. But french rafales where locked up from BVR with no F-22 radars being detected.The article :
From Paris Air & Cosmos on 29/01/2010

Although French aviators showed off a great deal about the “beatings” inflicted by their Rafales on British Typhoons during the last ATLC exercise in the United Arab Emirates, very little was said about the confrontation between Dassault’s delta-wing aircraft and the American F-22As. In out-of-visual-range engagements, the American Raptors did not even condescend to turn on their radars, remaining invisible to the Rafale’s RBE2 [radar system] and Spectra [self-defense system] while precisely locating the electromagnetic waves from the French fighter, thus securing their AMRAAM [missile] launches from a secure distance. On two occasions at least, the F-22As also “tangled” with the Rafales in close combat, securing a “gun kill” each time without much difficulty.http://rafale.freeforums.org/atlc-in-uae-rafale-vs-typhoon-rafale-vs-f-22-t93-10.html
Have you been living under a rock for the last year or so?
Has this not been discussed to death in the past?
I’m pretty sure that the French did indeed mention their combat with the F-22’s. What happened in WVR that A&C doesn’t mention was that out of 6 engagements, the F-22 was able to score 1 (or maybe 2) gun kills. That leaves 4 or 5 engagements where the F-22 was unable to score a kill. The F-22 pilots did state that it was a very challenging aircraft in WVR.
There were no official BVR engagements between the Rafale and F-22. I’ve no doubt that the F-22 can passively detect and kill the Rafale when it has its radar on (hardly surprising). I bet SPECTRA, Falcon Edge, or PRAETORIAN can do the same thing. The question is- can SPECTRA detect the APG-77 radar when it is switched on? Or can the ALR-94 detect the Rafale with the RBE2 and SPECTRA jamming turned off? These are questions that no open information will provide answers to.
We know little or nothing about which modes were available to SPECTRA, RBE-2, APG-77, or the ALR-94 during the training exercises, or which scenario was taking place in the situations in question- were the aircraft simulating MiG-29’s, were the simulating SARH missiles, etc..? For all we know, the F-22’s and Rafales were not even engaged in combat or exercises against each other at all when the BVR kill occurred- actually this seems to be the case. With WVR at least we know that it was guns only, and AFAIK the advanced systems on the Rafale and F-22 did not come into play (guns only of course).
Quick! Someone ring Lockheed Martin and let them know their plane isn’t ready for production yet…
I guess you’re not really getting the whole, ‘gradual roll out of various block capabilities’, thing are you?
No-one is SAYING that EACH LRIP aircraft will be “all singing all dancing” airframes…
L-M has said til it is “blue in the face” that you shouldn’t be comparing F-35 to previous aircraft types, because it IS being done differently. Now that you’ve identified this for yourself, perhaps you can start grudgingly admitting there might actually be something to what they are saying?
Hmm?
The idea of releasing capabilities in “blocks” is neither new nor different and is pretty standard throughout defense procurement. This is a risk mitigation method which ensures that the customer is provided a product that meets at least part of their immediate needs and other, less pressing requirements are spun off into blocks for integration at a later date as need, money, and time permit. This is standard practice.
