DEBUNKING OF CHINESE WET DREAMS ABOUT J 10B SUPERIOTY OVER RAFALE
Chinese claims that i quote
I)The J-10B incorporates 1200 T/R AESA, which is larger than the 880 T/R RBE-2,
II)INCREASED COMPOSITES
III)BETTER RAM COATING
IV)DSI
V)136 Kn ENGINE
VI)Mach 2 speed
VII)20300 m service ceiling
I)The J-10B incorporates 1200 T/R AESA, which is larger than the 880 T/R RBE-2,
ans:
well
1st of all there is a lot of uncertanity about whether J10b really poses AESA or PESA .ok lets us assume what NIET claims is
correct that J10b indeed has an AESA radar but still we dont have any accurate infos about it's specification like detection range ,scan rate ,peak power,
but we do get some idea about china's AESA radar from this chinese source that it may be having 1152 T/R modules

AESA radar for J-10B will have 1152 T/R module
well it's didn't signify any thing about it's detection range ,scan rate ,peak power, T/R modules compostion whther GaAs or GaN ??
As the article described, the aesa radar configuration can be changed according to the nose size of the aircraft, for example, different T/R number for J-10 and J-11 .But still a long way to go for china to build an AESA radar of a fighter comparable in technology with US or European standard especially in terms of LPI(low probabilty of intercept) & electronic jamming.
also J 10b radar which we saw in net is a test model of AESA radar not a full production AESA radar which has around 8 IFF
dipole antenna in the main array each having capabilty of handling 2 targets at the same time which means 16 targets simultaneosly(according to WIKIpedia which the chinese members often say a very reliable source
)
in comparsiion RBE 2 aesa radar can track upto 40 air targets in look down & look up aspects in all weather under intense electronic environment
meanwhile
rafale though claimed to have 1000 T/R modules but Pics say it has around 880 T/R modules but that doesnt mean J10's aesa radar becomes superior as greater size radar may be powerful but that doesnt mean technologically superior.
Well the quality of /or technology used to built T/R module of an AESA radar is more important than numbers as it should be more reliable .Well Su 30 mki bars radar even if it's a PESA radar is a very powerful radar with long detection range but it is technologically inferior to AESA radar.
advantage of RBE 2 AESA radar
1) SAR (synthetic aperature mode)
2)MMIC (mono lithic microwave integrated circuits )/GaAs (gallium arsenide) technology T/R modules
in future it may be built with GAllium nitride modules with sat com abilty
Thales reveals 'cloud' concept for Rafale radar technologies
3) it creates a 3 dimensional ground map covering wide area forward of the aircraft during low altitude penetration mission
4) It's has much better LPI which is more important in todays aerial combat as todays fighter /Awacs ESM (electronic support
measures) or RWR (radar warning receiver) system are more powerful in detecting radar waves of fighter aircraft exposing it's cover or location in air which can be fatal in aerial combat.
5) It along with spectra system increases rafale's electronic jamming capabilty even further
6) enhanced detection of low observable targets & improved resistance to electronic jamming
7) much better 5th gen System core / COTS for faster computation
Conclusion
U just cant compare the technological experience of china in buiding AESA radar with the french Thales which have decades of experience in building radar starting from Mirage 2000 to rafale rbe radar.If thats was not the case why would have pak airforce officials died to have french avionics in their JF17 in comparision to chinese
II)INCREASED CONCENTRATION OF COMPOSITES
ans:
& thats absolutely B.S
J10b' s composites concentration is no way greater than Rafale infact dassault itself claims rafale's composite concentration is more than 70 %
Optimized airframe
Hexcel company of france which supplies composties to rafale are pioneer in developing composites for aircraft meanwhile god knows what is the standard of chinese composites .????
Hexcel Composites - France
Hexcel.com - Carbon fiber and composites for aerospace, wind energy and industrial
III)BETTER RAM COATING
Ans:
another garbage assumption!!
rafale has much high quality RAM coating than j10 ,and what cheap quality RAM coating china uses we can see from the
pics of J20 when white flecks or patches are visible on plane surface when RAM shed off it's surface.Only J20 looks shiny in
photoshop pics only.
infact RAM coating can be seen in such places in rafale where u dont find in j10b
like external refuelling probe ,
IV)DSI
ANs:
yes 1 innovative thing for J10b
DSI has an advantage in performance & some aspects in stealth as it removes the gap present in between the diverter blade
& fuselarge of the plane.but to be fair enough it has no major role in combat.
But some analyst says DSI cant withstand mach 2+ Speeds which is yet to be proven ???? optimum speed for DSI is around
MACh 1.6-1.7 like that we see in jf 17 & F-35 So it needs to be seen can J10b achieve mach 2+ speed which J10A claims to have
V)136 Kn ENGINE
ans:
WS 10A 132 Kn engine right from the very beginnning has been under lot of scrutiny though chinese are determined to induct it no matter how good or bad it performs.Though WS 10b has been boasting of 136 Kn along with TVC which is still in development .Yes they have inducted WS 10a engines in J11b & even j-15 is going to have those engines ,but those are twin engine fighters
meanwhile inducting a single INDIGENIOUS engine fighter hasnt been so easy for chinese may be inducting a twin engine fighter with indigeniuos engines is more safer & reliable in comparision to a single indigenous engine fighter.Well same goes for WS 13engines i think for Jf17 also .& that too rumours ofchinese buying russian engines keep on popping in the media or internet every now & then .
infact serious misconception exists in the mind of our chinese friends about WS 10A 136kn advantage over Scnema M88 3 engine
u should understand thrust to weight ratio of plane is more important than thrust of engine of a plane
which rafale Thrust/weight ratio : 1.10 (100% fuel, 2 EM A2A missile, 2 IR A2A missile) excels in comparision to
J10b Thrust/weight ratio : 0.96 (with AL-31); 1.017 (with WS-10A) thaanks to it's twin engines fighter
other advantages of Rafale's M88 3 /M88 eco engines
1) it can supercruise but WS 10A no
2) it has far less IR signature than WS 10A thanks to it's 2 cooling channels
3) it's better engine TBO
4) scenema FADEC is much superior to WS 10a
VI)Mach 2 speed
Ans:
another funny ideology i think one should understand that plane cannot attain mach 2 speed every time if it does that it would be through help of after burner the plane would ran out of entire fuel stored in it & it would increase plane's IR
signature a lot which would be visible by enemy' IRST like rafale's FSO which is claimed to be capable of detecting IR signatures of plane from 120km .
well it is much better to have supercruise planes which doent need after burners to maintain speed which rafale has .If thats
the case then Mirage 2000 which has a top speed well above mach2+ would be superior to F-35 which has mach 1.7 as top speed
VII)20300 m service ceiling
ANS:
i would rather say it's vintage aerial combat ideology our chinese friends beleive that having a faster plane with higher ceiling would help them to release BVR missiles at such height which would give their BVR missiles more kinetic energy with more range & they would destroy rafale with it's SD 10 A or B misssiles at much longer range & rafale pilots would be sitting ducks & would not be having any self protection suite like SPECTRA in order to save their A$$es .LOOLLZ
well it's true that indeed BVR missiles range increase at high altitudes & with increased speed but it doent increase it's
kill probabilty of BVraam missile . Infact Kill probabilty of a missile depends upon the quality of seeker(IR or EM) of missile & abilty of ECM of enemy target plane rather than range of a missile.Meanwhile Rafale has one of the most deadliest
BVRAAM of this planet the Meteor worlds 1st ramjet powered missile having one of the largest No escape zone (NEZ)
&
MICA IR
bvaam missile which is one of longest IR missile availabe right now.
& for self protection against chinese missiles rafale has SPECTRA electronic warfare suite which i hope doent need introduction as everyone knows about it's capabilty
