In particular, the elastic structure is part of the moving boundary of the fluid, and the Navier-slip type boundary condition is taken into account. Depending on the reference geometry (flat or not), we show the existence of weak solutions to the coupled system provided the adiabatic exponent satisfies $\\gamma > \\frac{12}{7}$ without damping and $\\gamma > \\frac{3}{2}$ with structure damping, utilizing the domain extension and regularization approximation.
