A light ultrathin resin matrix composite air rudder belongs to the technical field of aircrafts and comprises a rudder framework and a skin. The rudder skeleton comprises an inserting area and grid ribs; the grid ribs comprise two types, one type is radial grid ribs which extend to the edges of the control surfaces from the inserting area, and the other type is transverse grid ribs which are connected between the control surfaces; and the skin covers the rudder skeleton, adopts a variable thickness design and is used for providing the rigidity of the rudder surface. According to the air rudder, the drag reduction target is achieved, the rudder surface of the air rudder is thinned so as to increase the design space for heat protection, a high-temperature-resistant and high-rigidity resin matrix composite material is adopted as a main force bearing structure of the rudder surface, and the requirements for heat protection and bearing capacity are met.

The invention relates to an irregular region cluster uniform distribution resolving method based on stress diffusion, and provides a uniform distribution resolving method for forming a cluster by a given number of devices based on a stress model, deploying the cluster in an irregular region on a spherical surface, and requiring the deployment position to be as uniform as possible. In the resolving method, the irregular area is required to be in single communication, a given number of point positions are randomly generated in the area during initialization, the point positions are diffused to be uniformly distributed through a repulsive force diffusion model, and the point positions slide when touching the boundary of the area and are static at the corners of the area. The method can be expanded from a spherical surface to a three-dimensional or more space, and is applied to solving of problems such as unstructured grid division and generation, detection, exploration, limited coverage and ...
