Abstract:

Results of a comprehensive investigation of Minuteman exhaust plume electrical properties are presented. Electron density and electron-neutral collision frequency profiles are given for the Stage 1 plume at 100 kft and the Stage 2 plume at 118,200 and 300 kft. This work is motivated by the need to determine plume electrical conductivities, input data to an evaluation of EMPexhaust plume interactions. The calculations are described in detail and include analyses of 1 two-phase nozzle flow via the method of characteristics, 2 nonequilibrium chemistry along nozzle and plume streamlines, 3 inviscid plume properties via the method of characteristics, 4 turbulent mixing nonequilibrium chemistry along curved plume boundaries, and 5 nonequilibrium chemistry behind the Mach disc. The results include gas and particle properties and chemical kinetic distributions of all neutral and charged species concentrations in the nozzle inviscid boundaries, shock structure, Mach number contours and electron densities in the plume.
