Title: Near Surface Flow Control Using Magnetohydrodynamics in High Mach Number Flight
Agency / Branch: DOD / USAF
Contract: FA9550-05-C-0151
Award Amount: $99,995.00


The purpose of this project is to demonstrate the effectiveness of a Cathodic Arc Plasma Sources (CAPS) and Power Processing Unit (PPU) for producing dense, high current (> 1 amp) plasma flows for magnetohydrodynamic (MHD) control of hypersonic flight surfaces. The CAPS source and PPU were developed for aerospace applications and have been optimized for weight and efficiency. The main advantage of the CAPS sources is that the plasma is generated independently of the current flow, and because of this, high-density, diffuse plasmas with large currents are possible. To characterize the effectiveness of the CAPS plasma source and measure the MHD effects, it will be installed into a model wing section and tested in a hypersonic (Mach 5.1) wind tunnel. The performance, efficiency, power consumption, power/weight ratio, and optimum velocity and altitude range will be determined under flight conditions. In addition, finite element computer simulations will be performed and compared to the experiment results.
