Y-20 heavy transport aircraft News & Discussions

Any guess ? How long will it take in the publication of official stats ?

some info already out

The performance parameters of the Y-20 are quite close to those of Russian Il-476. Operated by three aircrew members, the Y-20 has the highest load-carrying capacity of 66 tons, a fuselage length of 47 meters, a wingspan of 45 meters and a height of 15 meters, and bears the maximum take-off weight of a little more than 200 tons. It has a traditional layout and strong adaptability to take-off and landing fields, as evidenced by being able to take off and land at airstrips and carry the vast majority of combat and support vehicles of the Chinese People's Liberation Army (PLA).

while china busy building that. uncle is working on these..

i hope china have something similar on paper. need to stop playing catch up :lol:

Well there has been reports on SAC programme of creating an PLAAF version of X-47B.
 
This is what China is Working on right Now.

You don't want it to be so stiff unless you want it to crash every time when it lands.
Find a C-17 landing video and you will see similar vibration.

it seems the stiffness(刚度) of the tail wing is not big enough by your second video. we can see clearly the vibration after its landing.
after the first flight many details will be improved.:china:

Yeah, these wings must have tremendous tensile strengths.


@0:16 the wings of a C-17 also flexed upon landing. This is superb engineering and material science without them wings will break


And this also gives us an idea:

To the naked eye, an aircraft would look like a rigid object of metal flying in the air whereas the aircrafts fuselage can actually grow a bit during flight and the wings can flex almost 15 feet on some aircrafts.

Fact about airplanes

This is pretty similar to the situation of very tall buildings that flex to accommodate strong wind loads. Scientists have learnt it well from bamboos!
