Investigation of Rocket Powered, Open Cycle, Magnetohydrodynamic Generators for High, Pulsed Power Needs in Space.
Abstract
This investigation examined the possibility of using a rocket powered magnetohydrodynamic generator for pulse power in space of 300 megawatts (MW). The result is a preliminary design of an MHD generator using an open cycle disk channel and a single superconducting solenoid coil. The disk channel acts as a thrust deflector, and internal vanes counteract induced vorticity. The use of a solid fuel wafer grain design rocket motor is proposed for increased electrical conductivity and pulse operation of the generator. Using conservative parameters, a generator design capable of being carried on one or two space shuttle launches is developed with estimated mass of 24,450kg and estimated power output of 1346MW. The nominal operation time before refurbishment is 115 seconds; the restriction operation time is deterioration of the channel throat. This design exceeds present nuclear and solar cell power systems in power output per unit mass. (Theses)
