Simulation and Test of a Special Configuration Subsonic Cascade

This paper investigates the subsonic aerodynamic characteristics of an aircraft engine bypass duct cascade with a special structure consisting of integrated strut and outlet guide vanes, using a combination of numerical calculations and wind tunnel tests at different angles of attack. The test measured the outlet flow angle of the cascade and the static pressure distribution on the blade surface. By comparing the experimental and numerical simulation results, it is found that there is good consistency between them, which also verifies the reliability of the numerical simulation.
