Abstract

By an electrodynamic flow control using a magnetic field interaction in a weakly ionized plasma flow, the aerodynamic force acting on hypersonic vehicles could be controlled without any mechanical architecture. The side force is generated on the symmetric body if the magnetic field is inclined against the body axis. The in-plane component of the side force based on the plane defined by the body axis and the magnetic pole is straightforwardly expected to generate because the magnetic field is no longer symmetry, and it was confirmed experimentally.1 On the other hand, the recent numerical study suggested that the out-plane component of the side force is also generated by the Hall effect even if the configuration such as the geometry and the magnetic field is symmetry.2 In the present study, the out-plane component of the side force acting on a magnetized model is experimentally measured utilizing the arcjet wind tunnel to verify the generation of it. As a result, it is confirmed that the out-plane force acts on the experimental model when the magnetic field is inclined against the body axis. This experimental result agrees with the numerical simulation.
