建立了EE舱通风失效状态下温度计算模型,计算了热天巡航状态下通风失效后EE舱空气温度变化。针对通风失效后一段时间内EE舱空气超温的情况,提出了通风失效后可关断部分不影响飞行安全的电子设备以降低进入EE舱的热流、利用飞机内外压差产生的排气冷却备份、降低绝热层热阻等设计和操作措施的建议。
The temperature calculation model of EE cabin under ventilation failure was established, and the change of air temperature of cabin EE after ventilation failure was calculated. Aiming at the over-temperature of EE air in a period of time after the ventilation failure, the electronic equipment which can turn off the part of the air which does not affect the flight safety after ventilation failure is proposed to reduce the heat flow into the EE compartment. The exhaust cooling backup , Reduce the thermal insulation resistance and other design and operation of the proposal.
