| Popis: | Under the US Air Force sponsored Hypersonic Vehicle Electric Power System (HVEPS) program the authors’ organizations are collaborating on research and development of magnetohydrodynamic (MHD) power for an advanced high power, airborne electric power system. This program has been active for the past six years with various technical tasks being addressed that have encompassed engineering investigations of a myriad of technical issues related to airborne hypersonic MHD power system integration and operation. In the latest efforts of this program MHD power demonstration ground tests were successfully accomplished in August of 2007. The MHD power tests were conducted in the University of Tennessee Space Institute Propulsion Laboratory wherein a test cell was assembled for direct firing of an MHD generator with a high pressure combustor using a fuel mix of aluminum powder slurried in JP aviation fuel burned in oxygen. A heat sink Hall configured Hall MHD generator channel was installed in-line with the combustor and situated within the bore of a split-coil, superconducting magnet that was made available by NASA. The MHD power tests consisted of several test firings on separate days at peak magnetic field strengths of 1.58 and 1.8 Tesla. In all tests, significant levels of MHD electric power were produced at different MHD generator resistive load settings. The MHD performance was achieved at near maximum power operating conditions and the design targeted level as predicted by the HVEPS program. This paper presents the experimental program and data from the HVEPS UTSI MHD demonstration tests and provides MHD performance analysis of these data. |
