Abstract:

During this phase a lightweight, high performance hot gas flow train using liquid oxygen and JP-4 was designed and component modeling completed. The magnetohydrodynamic channeldiffuser performance parameters which were used as the design criteria were an output power of 30 MWe, a specific energy extraction of 1.0 MJkg, and a specific power density of 200 MWecu.m. To achieve these performance requirements, the required characteristic velocity efficiency of the combustion system was greater than 99. During this program a limited amount of development testing was completed using a heat sink combustor and a diagnostics channel. These tests measured the combustor characteristic velocity efficiency and the gas electrical conductivity, as well as pressures, vibrations, and temperatures. The results of the development test program, which verified the design assumptions used to achieve the performance requirements, were a characteristic velocity efficiency of nearly 99 and a gas electrical conductivity at the magnetohydrodynamic channel inlet of 15 mhosm.
