民用飞机引气泄漏过热探测系统是用于探测飞机高温引气管路泄漏,保护引气管路周围的结构或设备。探测器告警温度的选取直接决定了探测器能否及时并准确的探测引气管路泄漏。对共晶盐引气泄漏过热探测器告警温度的设置进行了研究,给出了共晶盐过热探测器告警温度计算分析方法。 Civil aircraft bleed air bleed overheating detection system is used to detect aircraft high temperature bleed air line leakage, the protection of the structure around the air bleeder or equipment. The selection of detector alarm temperature directly determines whether the detector can timely and accurately detect the bleed air line. The setting of the warning temperature of the eutectic salt leaking overheating detector was studied, and the calculating method of the alarm temperature of eutectic salt overheating detector was given.
