A test program was conducted to determine the aerodynamic and thermal operating characteristics of a 45-deg slant-wall, magnetohydrodynamic generator channel under no-power conditions. The generator channel was 32.3 in. long with an inside diameter of 2.0 in. at the inlet, diverging to 4.9 in. at the channel exit. The plasma was provided by a liquid oxygenJP-4 combustor having a nominal nozzle exit Mach number of 1.55. A solution of cesium carbonate dissolved in water was injected into the combustor to produce a high ion concentration in the exhaust stream. Nominal combustor operating conditions were as follows chamber pressure, 220 to 275 psia oxidizer-to-fuel ratio, 2.5 to 4.6 cesium concentration, 0.0 to 8 percent of total flow. Firing durations ranged from 4.6 to 7.6 sec. Tabulations of combustor operating conditions and a discussion of channel operating characteristics are presented.
