Both aircraft have RAM and composites, but they lack airframe upgrades like DSI or conformal bays.
Your claim was that Chinese aircraft has surpassed the Europeans (Typhoon and Rafale). Without choosing sides lets take a look at your points.
Firstly, lets assume that both Europeans and Chinese aircraft use RAM and composites this tells us one thing--absolutely nothing. The DSI nonsense that Chinese aviation enthusiasts hyped to epic proportions needs to be toned down. You do not need DSI to reduce or hide compressor blades, the Rafale uses 'S ducts' and you knew that very well yet to awe your fellow Chinese enthusiasts or make Chinese aircraft look extraordinary you threw in 'DSI'.
And what exactly do the J-20's weapons bays have anything to do with the Typhoon or Rafale? You are comparing fully operational and matured platforms to a prototype.
The Rafale currently uses a Thales RBE-2 PESA radar. An AESA is in development for 2012, but until it gets ready, the Rafale still uses PESA. Eurofighter's CAPTOR will be set for 2013. India selects their aircraft for their prices and availability, not just capability. For example, India rejected the MiG-35 not because of its capability, but its engine. Are you implying that the MiG-35 can not compete with Eurofighter or Rafale because India rejected it?
What makes you think that an aircraft with AESA is automatically superior to one with PESA? A radar and aircraft can be broken down in to many parts in terms of systems avionics. Important features in a radar include range, resolution, A2A-A2G modes, targets tracked, targets engaged, yada, yada, yada.
AESA=better than PESA. AESA equipped aircraft does not necessarily mean it is better than PESA equipped aircraft. And the latest report was that it was not because of engines. Politics and needs certainly played a role but besides that the aircraft were very much judged on capability, I believe that all aircraft were judged on a 600 point scale? And although much of the point scale was likely technical data some of it was likely simple performance such as high altitude performance which was one of India's requirements. But cutting threw all the MRCA nonsense we know that the Indians evaluated all aircraft on a comprehensive scale that numbers in the hundreds.
Meaning they broke down the performance of individual parts in to many--the radars could have been judged on dozens of different functions.
The Super Hornet has a stealthy airframe (slanted vertical stabilizers, redesigned intakes) as well as an AESA radar already. And then there is the maneuverability. The Eurofighter and Rafale are not up to par with the Super Hornet in BVR combat. SPECTRA adds LPI to the radar, which is already achieved by an AESA radar or a stealthy airframe. Nanjing competing with Thales is a very real possibility. They revealed an AESA radar 3 years earlier than Thales. They built, according to an employee, the world's largest AESA radar to be installed on a 5th generation fighter. They are now testing a similar SPECTRA system. What evidence do you have that suggests they can't potentially compete?
I assume you speak from experience? Or know something that most of us do not? The Typhoon for one has been know to dominate in A2A combat there is also a story some years back to one managed to achieve an F-22 lock, I do not know if it's true or not but even if we disregard that news you can not disregard the fact that the aircraft's systems as a
whole is what achieves victories not just one system. You are completely ignoring systems such as data-links, passive systems and weapons, or even RWR's and their ability to acquire a threat.
And please stay on topic, the conversation is about you claiming that Chinese aircraft air superior to European ones, there is no need to branch off in to off topic subjects or compare US aircraft to the Europeans when the topic is not about US aircraft. If I didn't know better I would say that you are going in circles.
What subsystems are you talking about?
A I mentioned the various parts and features of a radar, data-link, passive as well as active systems and weapons, ect, ect. For all you know the Spectra can deny a an AESA to see the Rafale, so again, what makes you think that that simply because an aircraft has AESA that it is a superior aircraft? And notice how a say aircraft (aircraft as a whole)--not radar.
