New restrictions on what PLA watchers can and can't talk about. Straight from the top.

Will this really effectively completely kill all the Weibo posters?

Quite unfortunate.

from Chengdu on a variable-camber flap with a continuous bending surface.

Abstract: The invention relates to the technical field of structural design of variant aircraft, in particular to a flexible control surface capable of continuously changing camber, which comprises a plurality of unit deformation modules, wherein each unit deformation module comprises a rigid actuating system and a flexible deformation structure...

This makes a lot of sense now! But I wonder if the skin will experience a lot of wear and tear and be maintenance heavy.

It could be the landing of the first flight.

I don't know, but the Chengdu patent in my last post cites a

from Harbin Institute of Technology (Shenzhen campus). The patent is on a bendable honeycomb structure with pneumatic artificial muscles and covered by an elastomer skin, which are touted for their high wear and tear resistance.

Abstract: A deformable skin structure with a designable Poisson's ratio, which relates to a wing skin structure, to solve the problem that the existing skin structure cannot meet the requirement of having low deformation stiffness in the deformation direction and relatively low deformation stiffness in other deformation directions. High structural rigidity to withstand aerodynamic loads and inertial loads, it includes a honeycomb structure matrix, flexible elastomers and multiple pneumatic artificial muscles; the honeycomb structure matrix is a positive Poisson's ratio honeycomb unit body and a negative Poisson's ratio honeycomb unit The honeycomb structure body is mixed and arranged, and the flexible elastic body is poured on the honeycomb structure matrix and a plurality of aerodynamic artificial muscles to form a flexible panel. The invention is used to make aircraft wing skin.
