Sealing shroud ring for sealing flexible plate of wind-tunnel nozzle section and preparation method thereof

The invention discloses a sealing shroud ring for sealing a flexible plate of a wind-tunnel nozzle section. The sealing shroud ring comprises sealing shroud ring bodies. Each sealing shroud ring bodycomprises an air bag and a sealing strip. Each sealing strip is provided with a fixing groove, each air bag is fixedly connected with a connecting rod matched with the corresponding fixing groove, andthe connecting rods are clamped in the fixing grooves. A sealing structure for the flexible plate of the wind tunnel nozzle section and the side wall involves the flexible plate and the equipment side wall. According to the sealing shroud ring for sealing the flexible plate of the wind-tunnel nozzle section, the air bags are special-shaped sections with the connecting rods, and the fixing grooveswith the same size as the sections of the connecting rods are designed in the sealing strips, so that the air bags and the sealing strips are effectively combined together, and the sealing shroud ring plays a role in sealing w
