EXPERIMENTAL PERFORMANCE OF A HALL MAGNETOHYDRODYNAMIC ELECTRIC POWER GENERATOR
Abstract
A test program was conducted on a Hall Magnetohydrodynamic generator. The internal dimensions of the generator channel diverged from 4 in. in height at the channel inlet to 6 in. in height at the channel exit, and the width was 2 in. along the 48-in. length of the channel. 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, 1.3 percent of total propellant weight flow, magnetic field, 20,000 gauss; and load bank resistance, from 0 to 24.9 ohms. Tabulations of combustor performance data and of the generator electrical data are presented.
