| Abstract: | Under the basis of the anslysis and statistics to a large number of data of trial run and flight telemetry from different models of Long March Rocket, this study has found a new mathematical model for starting process of pressurizing transmission system, and studied mathematical simulation by the use of modern computer simulation technique. The computing results is the same as ones of flight telemetry. The use of the models can greatly decrease the error of theoretical computation, increase the precision of pressurizing computation. |
