Re: China's Transport Aircraft
Basically, this is what I wrote a while ago.
Y-9's range with 15 t payload is 2200 km accordng to Huitong. It looks semi-credible if we look at Y-8 figures from SAC website.
For Y-8F400,
Range at maximum payload of 15t is given as 2150 km. Ferry flight range is 4500 km.
For Y-8F600
Range at maximum payload of 20t is given as 1700 km. Ferry flight range is 4800 km.
So, we could do an estimate on 15t range of Y-8F600 by 2150 x (4800/4500) = 2293 km. If Y-8F600 is more efficient relative to Y-8F400 at higher payload, then maybe that range can be increased to 2400 km.
Y-9 maximum is 5800 km according to its Chinese designers in this flightglobal article. So, if we do our previous calculation, 2150 x (5800/4500) = 2770 km. So, around 2800 km for 15 t, better than 2200 km claimed by Huitong, but still pales to C-130J
From ,
Range with 35,000 pounds of Payload: (15.9 t)
C-130E, 1,438 miles (1,250 nautical miles) -> (2314 km)
C-130H, 1,496 miles (1,300 nautical miles) -> (2407 km)
C-130J, 1,841 miles (1,600 nautical miles) -> (2962 km)
C-130J-30, 2,417 miles (2,100 nautical miles) -> (3889 km)
There is what you believe and there is also reality. Y-9's specs are public. I need to dig them up and post them here sometimes.

look at the range difference with 15 ton payload. On top of that, they still require 4 pilots for Y-9. Who are these countries that would be in line for these second hand Y-9s?PLAAF can order many Y-9 and when Y-20 is finally enter service and in significant numbers. PLAAF can sold this second hand Y-9 with decent airframe to other countries. They offer an attractive alternative compare to C-130J.
I posted the relevant parts above.Cant find it. Besides, how do you know y-9 performance? the plane has barely started flying.
Anyway, besides the new engine, what are the diferences betwen y-8 and y-9?
I think Y-9 payload shall be more than 30 tons and comparable to France A400. Given the new six blade composite turboprop engine. I can't believe if it still have a payload of only 20tons.
