In this paper, an experimental study on structural deformation of serpentine nozzle for turbofan engine is carried out?and the reliability of one-way/two-way fluid-structure coupled was verified. The deformation is mainly located in the second bend channel, and the two-way fluid-structure coupled method can more accurately simulate the aerodynamic deformation characteristics of the nozzle.
