Chinese advanced (stealth) air vehicle projects
« on: February 22, 2013, 12:55:25 pm »
Hi.


On 06/09/2011, a team of 6 engineers from China's AVIC Chengdu Aircraft Research Institute filled a patent for an advanced supersonic weapon system of interest described as "a canard tailless aerodynamic configuration"


Abstract translates roughly as : "The utility model belongs to the technical field of the design of unmanned aerial vehicles, and relates to variant canard tailless aerodynamic configuration, which can realize flight with a high subsonic lift-to-drag ratio and a high supersonic lift-to-drag ratio simultaneously. Canards are arranged at the front of an airplane body, and can be folded and unfolded, wings are arranged on the rear of the airplane body, wing tips of the wings can deflect vertically, an air inlet channel is disposed at the front of the upper surface of the airplane body, a tail nozzle is arranged at the tail of the airplane body, and control surfaces are arranged on the rear edge of the airplane body and the rear edges of the wings. The variant canard tailless aerodynamic configuration adopts the design, the left and the right of the variant canard tailless aerodynamic configuration are symmetric, requirements of cruise at a high subsonic lift-to-drag ratio and supersonic penetration on aerodynamic force are efficiently met by the aid of the variation technology that the foldable wing tips and the foldable canards are combined, and contradiction of subsonic stealth cruise and supersonic flight heading stability on aerodynamic configuration is coordinately solved. The variant canard tailless aerodynamic configuration can be applied to the aerodynamic configuration design for various unmanned supersonic aircrafts."

Hmmm ... that's interesting, since it matches this model I found some time ago !
He was my North, my South, my East and West,
My working week and my Sunday rest,
My noon, my midnight, my talk, my song;
I thought that love would last forever; I was wrong.
...
For nothing now can ever come to any good.

Perfect match. Is there any date associated to this RC model?

It is one of the concepts that were presented at latest Zhuhai airshow. They came from innovative designs competition.

Bizarre aviation expert.

Interesting ... and we all know that the first "glimpse" of the J-21/-31 was also a model shown at a similar contest a year before that ...

Hi. What do you think of that. it was posted today as the 'new chinese stealth bomber'

That's surely not a "bomber" not even by its size.

Following some big-shrimps that - even if blurred - image is said to be the first prototype of the Shenyang "Sharp Sword" UCAV-demonstrator (said to be similar to the US X-47B - but IMO more likely to the Neuron). It is designed by the Shenyang Aircraft Corporation and its design Institute No. 601 and was allegedly build at Hongdu. Reportedly it had its first taxi test the very same day the Y-20 had its maiden flight.
