“…"AJAX" hypersonic vehicle concept [3] As an important part of AJAX concept, MHD-enhanced control for aerodynamic and operability performance of hypersonic vehicles is actively being investigated abroad. The major MHD applications proved by elementary researches in hypersonic vehicles can be classified as inlet flow control [4], power generation [5], jet acceleration [6] and fuel mixing enhancement [7].…”

The magnetohydrodynamic (MHD) flow control techniques for inlet based on “AJAX” vehicle concept have attracted many researchers’ attention for its potential wide applications in the supersonic flights or the hypersonic ones. In this paper, a preliminary discussion for basic problems that are ionization and magnetic field in the MHD applications is presented. And three major MHD techniques for enhancing inlet aerodynamic performance and operability, which are large scale flow control for enlarging flight scope in Mach/angle-of-attack, near surface flow control for shock wave/boundary layer interaction and leading edge heating-transfer control for enormous thermal load on leading edge of the compression ramp, are briefly explained and reviewed.

Over the past several years, efforts have been under way to design and develop an operationaUy flexible research facility for investigating the use of cross-field MHO accelerators as a potential thrust augmentation device for tbermal propulsion systems, The baseline configuration for this high-power experimental facility utilizes a 1,5-MW, multi-gas arc-heater as a thermal driver for a 2-MW, MHO accelerator, which resides in a large-bore 2-tesla electromagnet. A preliminary design study using NaK seeded nitrogen as tbe working fluid Jed to an eIternaUy dlagonalized segmented MHI> cbannel configuration based on an expendable beat-sink desigu concept. Tbe current status report includes a review of engineering/design work and performance optimization analyses and summarizes component bardware fabrication and development efforts, preliminary testing results, and recent progress toward full-up assembly and testing
