模拟来流参数误差对固体冲压发动机地面试验结果影响的评估
Evaluating of influence of simulating coming flow error on the SDR ground test
摘要
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-di-mension 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 performance parameters on simulation error and the applying range of small deviation model,and put forward a suit of fairly integrated performance calculating method of solid ducted rocket in consideration of coming flow regulating error and regulating precision of total pressure and total temperature during the direct-connection ground test of SDR.关键词
