| Abstract: | In the ground test of solid ducted rocket(SDR),influence of the simulated coming flow error on the test result is very significant,so the research of related influence evaluation has an important theory meaning and engineering value.Based on one-dimension aerodynamics theory and combined with some type of test solid ducted rocket,the influence of simulated coming flow error to ground test of the SDR was evaluated by means of the small deviation model to provide the sensitivity coefficients of motor performa... |
