【摘要】 研究了载人飞船环控生保系统主要故障模型及飞控对策,根据系统工作原理建立了影响飞行安全的主要故障模型,如舱体泄漏、气源消耗过量和CO2净化失效等,应用该类模型对飞行数据进行实时处理,判断或预测故障,同时给出飞控对策。该方法已成功应用于首次载人飞行。更多还原

【Abstract】 In this paper malfunction models and aviation countermeasure for the Environmental Control &Life Support System(ECLSS) of manned-spacecraft were studied. The primary malfunction models which would affect flight safety, such as chamber leakage, gas storage excessively consumed, carbon-dioxide decontamination failure, etc, were conducted from system schematic diagram, and used to analyze flight data dynamically for failure judgement, from above the countermeasure could be derived. This method was applied in the first manned-space flight successfully.更多还原
