EXPERIMENTAL PERFORMANCE OF A 60-DEG-SLANT, SEGMENTED WALL, MAGNETOHYDRODYNAMIC ELECTRIC POWER GENERATOR
Abstract
A test program was conducted on a 60-deg-slant, segmented wall, magnetohydrodynamic generator. The generator channel was 48-in. in length with an inside width of 2-in., and diverged from 4-in. in height at the channel inlet to 6-in. in height at the channel exit. The plasma was provided by a gaseous oxygen/RP-1 combustor with a Mach number 1.6 nozzle. The propellants were seeded with potassium hydroxide (KOH) dissolved in ethyl alcohol to produce a high ion concentration in the exhaust stream. The generated power was dissipated through a resistor load bank with a variety of parallel and series resistance configurations. Operating conditions were nominally as follows: combustor chamber pressure, 46 psia; KOH concentration, from 0 to 1.8 percent of total propellant weight flow; magnetic field, 20,000 gauss; and load bank resistance, from 0 to 61.5 ohms. Tabulations of combustor performance data and of the generator electrical data are presented.
