AERODYNAMIC AND THERMAL OPERATING CHARACTERISTICS OF A 45-DEG-SLANT, SEGMENTED WALL, MAGNETOHYDRODYNAMIC GENERATOR CHANNEL UNDER NO-POWER CONDITIONS

Abstract

A test program was conducted to determine the aerodynamic and thermal operating characteristics of a 45-deg-slant, segmented wall, magnetohydrodynamic generator channel under no-power conditions. The generator channel was 30.3 in. long with an inside diameter of 2.0 in. at the inlet that diverged to 4.9 in. at the channel exit. The plasma was provided by a liquid-oxygen/JP-4 combustor with a nozzle exit Mach number of 1.76. The propellants were seeded with potassium hydroxide (KOH) dissolved in ethyl alcohol to produce a high ion concentration in the exhaust stream. Combustor operating conditions were nominally: chamber pressure, 250 to 300 psia; oxidizer-to-fuel ratio, 1.9 to 2.8; and KOH concentration, from 0 to 1.7 percent of total propellant weight flow. Firing durations ranged from 2.6 to 10.9 sec. Tabulations of combustor performance data and of the generator channel thermal and pressure data are presented.
