【Abstract】 A two dimensional mathematical model was developed to predict the performance characteristics for direct current, linear channel MHD propulsion system in a closed loop environment. The results of analytical and experimental studies of the linear channel MHD propulsor are described. Compared with the data of experiment, the correctness of the computation program is validated.更多还原
