PLAAF AWACS thread

Think about the geometry of the dish for a 360 coverage.

the VT and HT will obscure the rear view, so the option is always to avoid placing an antenna facing directly rear ward.

for optimal coverage 360/3 = 120 deg would be enough for electronic steering of the beam.

so you really can only place the 3 antennas in an inverted triangle.

an inverted triange is not good for aero or stability or aeroelastics.

if it wasn't the qualified radome ellipsoid shape, wouldn't there have to be an extensive
qual program to prove out the aerodynamics and drags counts? it was probably easier to stay with the same shape and just change out the internal components

does anyone know what kind of switches they use to steer the beam to lock onto targets. wouldn't this switch require a lot of RF power handling capability or else they would burn out

Just "found" at XAC ... not sure if a Y-7-derivate or a completely new type, but anyway most likely something new again.

4 vertical fins.
nice.

this has to be one of the most important developments for PLAN. I'm not sure if it's Y-7 derivative either. The vertical tailfins obviously point to something that requires a lot of change from the normal Y-7/Ma-60 series of aircraft. So until we see a more clear picture, I can't say it's a Y-7 derivative.

[delft]

If you take Y-7, replace the tail with one with four fins, replace the undercarriage to enable it to operate from Varyag, replace the wing with one much stronger to cater for carrier landings and with folding outer panels, replace the engines with stronger ones with new propellers, replace the cockpit, redesign the fuselage to carry the larger forces, and the radar saucer, you would have nothing left of Y-7.

P.S. And if your going to use cats.....

[i.e.]

WJ-6C is used in Y-8 platforms are about 5100 shp each. it should be noted that allison T56 used in E-2 has about the same shp.

...This ^^ aircraft looks like a KJ-2000 with the radome missing..It's off topic anyway. This thread is about the PLAN aircraft carrier.. Back on topic gents! Back on topic!

But sorry - since You posted these two pictures - any confirmation, when they were taken ??

As such they must be either older photos since these markings with the red flag were from the time, when the KJ-2000 were newly converted from Il-76MD's. Or if these recent pictures ... then they are a sign that additional IL-76s are under conversion. ?!!

[Totoro]

I am trying to compile a set of images of different Awacs units, both kj200 and kj2000. Does anyone have images of kj200 beyond the original four? The alleged planaf units?

[tphuang]

This should be the planaf regiment from huitong's website

[Totoro]

Thank you, but my question is this: Which clear pics of serial numbers of kj200 have we seen so far?
30171, 30173 and 30174 for plaaf and now 9371 for planaf.

That is 4 units with circumstancial evidence for one more plaaf and one more planaf unit. Have there been any further sightings of any other serial numbers? (two planes for planaf doesnt seen enough to rotate planes on station)

that certainly looks like a E-2C Hawkeye,
probably the one that Taiwan has?

[tphuang]

we have 30171, 30173, 30174, 30175 and 9371 with another KJ-200 for planaf beside it. I mean we don't really need more KJ-200 photos to know that it will have 4 in that regiment if it doesn't already have it.

New photo of y-7 AEW wind tunnel model

http://radikal.ru/F/s47.radikal.ru/i...7103b.jpg.html

its the same wind tunnel

http://radikal.ru/F/s44.radikal.ru/i...07453.jpg.html

Someone said at keypublishing forum, that this wind tunnel is called NF-3, located in Mianyang in Sichuan Province and that its a old lowspeed tunnel. This is a old photo of the same wind tunnel

http://radikal.ru/F/s56.radikal.ru/i...7c325.jpg.html

So its confirmed that china has at least a wind tunnel model of an carrier based AEW. The question is: what ii its current status ?? still in model stage, or something else ??
