Design of Dehumidification System for Civil Aircraft

以建模和计算分析为手段,完成民用飞机干燥系统的需求分析和方案设计。首先建立民用飞机客舱横截面的几何模型和传热模型;基于饱和含湿量和温度之间的关系分析客舱顶部干燥控制需求;比较干燥控制需求和民用飞机典型巡航工况下的相关参数确定干燥系统设计方案;最后将设计方案与实际应用进行比照,实际应用和设计方案吻合较好,说明了设计过程的合理性。

Based on modeling and analysis, this paper applies for achieving requirement analysis and proposal design for dehumidification system of civil aircraft. Firstly, geological and thermal transfer models are set up based on cabin vertical section. Secondly, relationship between saturated humidity and temperature is analyzed to capture dehumidification requirement. Thirdly, comparing requirement and relative parameters on typical aircraft cruise condition, dehumidification system design is proposed. Lastly, the quantities of components applied on real aircraft, analysis and design rationality is demonstrated.
