Abstract

A concept of magnetohydrodynamic (MHD) acceleration of unseeded cold hypersonic flow using nonequilibrium electrical conductivity sustained by electron beams (e-beams) can substantially enhance performance of hypersonic wind tunnels, potentially enabling Mach 15 velocities at a dynamic pressure of 2,000 psf, as well as higher Mach numbers at lower dynamic pressures. The concept is intended to support the U. S. Air Force (USAF) Radiantly Driven Hypersonic Wind Tunnel/Magnetohydrodynamics Accelerator Research into Advanced Hypersonics (RDHWT/MARIAH II) Program. This paper describes the effort (ongoing and planned) to address the technical issues critical for the development of this concept. The program will be heavily leveraged with other existing and planned programs funded by the Air Force Office of Scientific Research (AFOSR), National Science Foundation (NSF), and National Aeronautics and Space Administration (NASA), using unique hardware purchased and developed under those programs.
