AI Technical Summary
In the existing technology, the connection reliability between the sealing strip and the flow channel plate is insufficient, which leads to the risk of breakage and detachment of the sealing structure when operating at high speed, affecting engine performance.
An elastic sealing strip is used, comprising an elastic body and a fabric covering layer. The adhesive strength is enhanced by setting the fabric covering layer at the adhesive surface, and the fabric covering layer is bonded to the flow channel plate through a specific manufacturing method.
It improves the bonding strength between the sealing strip and the flow channel plate, enhances the stability of the sealing structure, reduces the risk of sealing strip detachment and breakage, and improves the aerodynamic efficiency and overall performance of the engine.
