EXPERIMENTAL PERFORMANCE OF TWO SEGMENTED WALL MAGNETOHYDRODYNAMIC ELECTRIC POWER GENERATORS USING SOLID-FUELED COMBUSTORS
Abstract
A test program was conducted on a vertically segmented wall (Hall) and a diagonally segmented wall (45-deg-slant) magnetohydrodynamic generator. The internal width of the 48-in.-long generator channel was 2 in.; the height diverged from 4 in. at the inlet to 6 in. at the exit. The plasma was provided by a solid-fueled combustor with a nozzle designed for an exhaust gas exit Mach number of 3.75. Thirteen firings were made with the 45-deg-slant channel for power generation. Six firings were made with the Hall channel; three of these were for power generation, and three were made for exhaust gas conductivity measurement. Operating conditions for the power generation firings were: nominal combustor chamber pressure, 325 psia; magnetic field, 20,000 gauss; and load bank resistance from 0 to infinity ohms. For the exhaust gas conductivity measurements, voltage was supplied to the channel at levels of 360, 440, and 200 v dc. Tabulations of combustor performance and of the electrical data from the two generator configurations are presented.
